MLCC Pack Quantity by Case Size: 16 of 501 Hong Kong Stock Lines Pack at 1,000 Pieces or Fewer, Read for the United Kingdom

MLCC pack quantity on our Hong Kong shelf is decided by case size, not by the part. We measured all 501 lines carrying one, as at 23 September 2026: every 0201 packs at 15,000, every 0402 at 10,000, every 0603 at 4,000. Only 16 of 501 pack at 1,000 or fewer, and every one of those is 1210 or larger.

Venatech Limited, an authorised Walsin distributor in Hong Kong, publishes a dated stock position rather than a live feed. This post is written from two sources: our Hong Kong ready-stock snapshot as at 23 September 2026, and all 203 Walsin Technology (Walsin) parametric export files, which we used to attach a case size to every stock line. Every part number is real. Pack quantity is a packaging specification and is stated as such; no quantity of stock on hand appears anywhere here, because that is a dated figure and you should ask us for the current position.

What is the MLCC pack quantity at each case size on the Hong Kong shelf?

It falls monotonically as the part gets bigger, from 15,000 pieces at 0201 to 500 at 2220. We joined all 501 stock lines carrying a pack figure against 00_ALL_MLCC_parts_combined.xlsx and the 64 non-empty chip resistor export files to recover the case size for each, then grouped them. The ladder has eight steps — 500, 1,000, 2,000, 3,000, 4,000, 5,000, 10,000 and 15,000 — and no ninth value appears anywhere. We have published the eight steps before. What nobody has published is what they look like against case size, which is the only axis a design engineer can act on.

Case size	MLCC lines	MLCC pack quantity	Chip resistor lines	Chip resistor pack quantity	Match / mismatch between the two families
0201	9	15,000	4	15,000	Match — identical step
0402	72	10,000	81	10,000	Match — identical step
0603	72	4,000	100	5,000	Mismatch — the capacitor packs smaller
0805	49	3,000 or 4,000	30	5,000	Mismatch — capacitor smaller, and not single-valued
1206	24	2,000, 3,000 or 4,000	33	5,000	Mismatch — capacitor smaller, three steps in one cell
1210	5	1,000 or 3,000	none held	—	Mismatch — no resistor line at this size
1808	3	1,000	none held	—	Mismatch — no resistor line at this size
1812	4	1,000	none held	—	Mismatch — no resistor line at this size
2211	2	500 or 1,000	none held	—	Mismatch — no resistor line at this size
2220	1	500	none held	—	Mismatch — no resistor line at this size
2512	none held	—	2	4,000	Mismatch — no capacitor line at this size

The two ladders agree exactly at 0201 and 0402 and then separate. From 0603 upward the capacitor always packs smaller than the resistor at the same footprint, and by 1206 the gap is 2,000 against 5,000 — a factor of 2.5 on parts that occupy the same land pattern.

How many part numbers can a UK buyer get at or below each pack step?

Very few below 3,000. We counted the part numbers, not the pieces, at every step of the ladder. Two of 501 lines pack at 500. Sixteen pack at 1,000 or fewer. Twenty-five pack at 2,000 or fewer — 5.0% of the shelf. Two thirds of the shelf sits at 5,000 or fewer, and 97.4% at 10,000 or fewer.

Pack step	Part numbers at or below it	Share of 501	What a UK prototype buyer can choose from
500	2	0.4%	two specialty capacitor lines
1,000	16	3.2%	1210 and larger only
2,000	25	5.0%	1206 and larger only
3,000	62	12.4%	adds 0805 capacitors and two inductors
4,000	168	33.5%	adds every 0603 capacitor
5,000	335	66.9%	adds 163 chip resistors
10,000	488	97.4%	adds every 0402 part
15,000	501	100%	adds every 0201 part

A 1,000-piece requirement is a single pack on 16 of 501 lines and a multiple of the pack on the other 485. At the four smallest case sizes the floor is 3,000 pieces: nothing at 0201, 0402, 0603 or 0805 packs below 3,000, and nothing at 1206 or smaller packs at or below 1,000. If your UK prototype needs 500 of an 0402 capacitor, the pack as at 23 September 2026 is 10,000 and the conversation is about breaking a pack, not finding a smaller one.

Does the case size decide the pack quantity, or does the part?

The case size, on 413 of the 493 lines we could resolve. This is the measurement we had not seen made anywhere. We resolved 493 of the 501 pack-bearing lines to a row in Walsin’s published catalogue, grouped them by family and case size, and asked a single question of each group: does every part number in it carry the same pack figure? 413 of 493 lines, 83.8%, sit in a group where the answer is yes. Only four groups disagree internally, and all four are MLCC: 0805, 1206, 1210 and 2211.

Group	Lines	Distinct pack quantities	Match / mismatch vs “case size decides the pack”
Chip resistor, all six case sizes held	250	1 per case size	Match — 250 of 250 lines predictable from case size alone
MLCC 0201, 0402, 0603	153	1 per case size	Match — 15,000, 10,000 and 4,000, no exceptions
MLCC 1808, 1812, 2220	8	1 per case size	Match — 1,000, 1,000 and 500
Inductor 2520	2	1	Match — both at 3,000
MLCC 0805	49	2	Mismatch — 24 at 3,000, 25 at 4,000
MLCC 1206	24	3	Mismatch — 9 at 2,000, 8 at 3,000, 7 at 4,000
MLCC 1210	5	2	Mismatch — 4 at 1,000, 1 at 3,000
MLCC 2211	2	2	Mismatch — 1 at 500, 1 at 1,000

Every one of Walsin’s six chip resistor case sizes on our shelf carries exactly one pack quantity — 250 of 250 lines. Pack quantity on the resistor half of the shelf is a lookup on case size and nothing else. We have not seen this counted anywhere.

The exceptions are not random either. We read the series behind the four disagreeing groups in 00_ALL_MLCC_parts_combined.xlsx: at 1206 the three soft-termination SH lines all pack at 2,000 while General Purpose and Middle-to-High-Voltage lines at the same footprint spread across 2,000, 3,000 and 4,000. The disagreement sits with the series, not the footprint — which is why a cross result that changes series can change your pack increment without changing your land pattern.

Why does the chip resistor ladder flatten at 5,000 while the MLCC ladder keeps falling?

Because the resistor ladder stops stepping after 0603. We measured both: the MLCC ladder falls through seven distinct values from 0201 to 2220, while the chip resistor ladder uses only four — 15,000 at 0201, 10,000 at 0402, then 5,000 across three consecutive case sizes (0603, 0805 and 1206) and 4,000 at 2512.

That plateau covers 163 of the 250 resistor lines on the shelf. WR06W2R70FTL at 0603, WF08H8203BTL at 0805 and MF12E1R00FTL at 1206 are three real examples, three different case sizes, three different series, one pack figure. For a UK buyer the useful consequence is that moving a resistor up a case size for power headroom costs nothing in pack increment anywhere between 0603 and 1206 — whereas doing the same thing with a capacitor changes the increment at every step.

Part number	Family	Case size	Series in Walsin’s export	Pack quantity	Match / mismatch vs the next size up
WR02X1002FAL	Chip resistor	0201	Thick Film General Purpose	15,000	Mismatch — 0402 drops to 10,000
WF04H1202DTL	Chip resistor	0402	High Precision Thick Film TC100	10,000	Mismatch — 0603 drops to 5,000
WR06W2R70FTL	Chip resistor	0603	Thick Film General Purpose	5,000	Match — 0805 is also 5,000
WF08H8203BTL	Chip resistor	0805	High Precision Thick Film TC100	5,000	Match — 1206 is also 5,000
MF12E1R00FTL	Chip resistor	1206	Thick Film Triple Power Surge (Automotive)	5,000	Mismatch — 2512 drops to 4,000
0603B101J500	MLCC	0603	General Purpose Caps	4,000	Mismatch — 0805 drops to 3,000 or 4,000
1206B102K202	MLCC	1206	Middle to High Voltage Caps	3,000	Mismatch — 1210 drops to 1,000

Which part numbers pack at 500 pieces, and what are they?

Two lines of 501, and both are among the physically largest capacitors we hold. SH55B684K631 is a 2220 soft-termination part and S252B222K502 is a 2211 safety-certificated part. Those are the only two pack quantities below 1,000 anywhere in the snapshot, 0.4% of the shelf. The 14 lines at 1,000 are four 1210 General Purpose capacitors, three 1808 and four 1812 Middle-to-High-Voltage capacitors, one 2211 safety part and two lines with no row in Walsin’s published catalogue.

Two internal links are worth following here. For why there is no published minimum order quantity to look up in the first place, see SPQ and MOQ for prototype buyers, which measures the empty columns in detail. For why “0603” names two physically different parts across these two families, see passive component case sizes, imperial and metric. The resistor line is on the Walsin chip resistor page.

What should a UK prototype buyer ask for instead of an MOQ?

The pack increment on the specific part, as at a stated date. There is no published MOQ anywhere in Walsin’s 203 export files to ask for, and a reel-format string is not a quantity. A question that has a documentary answer is: what is the pack increment on this part number, and what did your snapshot hold as at 23 September 2026? We can answer both, and we will tell you when the answer comes from our own record rather than a datasheet.

1. Give us the case size tolerance in your design, not just the value. If an 0603 capacitor will accept a 1206, the pack increment falls from 4,000 to as little as 2,000. If it will accept 1210, it can fall to 1,000.
2. Cross the whole bill of materials in one pass. Paste up to 500 part numbers or drop your Excel or CSV into the free cross-reference tool — matched against Walsin’s published catalogue, with every difference stated — then ask us for pack increments on the candidates you would actually accept.
3. Check the current position before you commit a build slot. Our ready stock page is live and public, and what it shows is a dated snapshot, not a feed. Ask us what is there today.

The short version

We measured pack quantity against case size on all 501 lines of our Hong Kong snapshot that carry one, as at 23 September 2026. The ladder has eight steps and no ninth. Case size alone predicts the pack figure on 413 of the 493 resolvable lines, including 250 of 250 chip resistors; only MLCC 0805, 1206, 1210 and 2211 disagree internally. Every 0201 packs at 15,000, every 0402 at 10,000, every 0603 capacitor at 4,000 and every 0603 resistor at 5,000. Sixteen lines pack at 1,000 or fewer and all are 1210 or larger; two pack at 500. Nothing at 0805 or smaller packs below 3,000. Every figure comes from our own record, because Walsin’s SPQ and MOQ columns are blank in all 24 files that declare them. Qualification stays with you.

Send us the UK prototype quantity you actually need and the case sizes your layout will accept, and we will tell you which part numbers can be served as a single pack, which need a pack broken, and where we are reading our own record rather than a published specification. Then tell us this: when a distributor quotes you an “MOQ”, have they ever shown you the document it comes from?
