For consumer electronics in Brazil, the Walsin Technology (Walsin) ultra-small 01R5 series, the 0.4 by 0.2 mm 01005 class, reaches 100 nF in only 5 of its 317 parts, all X5R at 4 V to 10 V, and the 10 V one is among four rows with no dimensions in the export. None of the 317 is on the shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a Brazilian maker of phones, wearables or other compact devices, Manaus included, who is crossing a decoupling capacitor in the smallest MLCC case. It comes from the Walsin MLCC export (24,026 rows, 23,601 distinct part numbers; the 01R5 series is 317 of them) and our stock list as at 23 September 2026. Every part number is real. The market facts name their source and the day we fetched it, 10 November 2026.
What did Brazil’s Manaus industrial hub report for January to August 2026?
Revenue and phone output both rose. According to Agencia Gov (EBC) on 14 October 2026, the Manaus Industrial Pole billed 165.12 billion reais, about 31.98 billion US dollars, from January to August 2026, up 10.47 percent, and made 7,988,490 mobile phones, up 9.22 percent.
The same report put electronics at 15.22 percent of revenue and IT goods at 21.82 percent, and counted 3,694,753 microwave ovens, up 16.79 percent, and 8,706 desktop computers, up 57.52 percent. Those are the agency’s figures, not ours. The conclusion we draw is ours: a hub of that scale builds boards where the smallest capacitor case matters, and we say nothing about what any Manaus maker buys or designs.
Which Walsin 01005-class capacitors cross a 100 nF, X5R, 6.3 V brief, and what differs?
Five exist at 100 nF, and one is a clean match. We parsed the 317 Walsin 01R5 series parts and found 5 at 100 nF, all X5R, at 4 V, 6.3 V and 10 V; exactly 1, 01R5X104K6R3, matches a 100 nF, X5R, plus or minus 10 percent, 6.3 V brief on every export field.
Put your incumbent in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
01R5X104K6R3 |
Ultra-small 01R5, X5R, 100 nF, plus or minus 10 percent, 6.3 V, 0.40 by 0.20 by 0.20 mm | No | Match on dielectric, value, tolerance, voltage and size | |
01R5X104M6R3 |
Ultra-small 01R5, X5R, 100 nF, plus or minus 20 percent, 6.3 V | No | Mismatch: tolerance is plus or minus 20 percent, wider | |
01R5X104K4R0 |
Ultra-small 01R5, X5R, 100 nF, plus or minus 10 percent, 4 V | No | Mismatch: voltage is 4 V, lower | |
01R5X104M4R0 |
Ultra-small 01R5, X5R, 100 nF, plus or minus 20 percent, 4 V | No | Mismatch: 4 V and plus or minus 20 percent | |
01R5X104K100 |
Ultra-small 01R5, X5R, 100 nF, plus or minus 10 percent, 10 V, no dimensions in the export | No | Match on dielectric, value and tolerance; mismatch: 10 V, and size cannot be confirmed from the export |
A match in the table is a match on the export fields, no more. Confirm against both datasheets and qualify in your own circuit. Our guides to how to read a Walsin MLCC part number and to MLCC DC bias and voltage derating explain why a 100 nF value at 6.3 V is a smaller capacitance in service.
How far up does each dielectric go in the 01R5 series?
NP0 dominates and X7R stops early. We counted the 317 rows by dielectric: 276 are NP0 up to 220 pF, 32 are X5R from 100 pF to 100 nF, and 9 are X7R from 100 pF to 1,000 pF, so X7R never exceeds 1 nF at this size.
Voltages follow the dielectric. The NP0 rows are 16, 25 and 50 V on 271 parts, with 5 at lower voltages; the X5R rows are 10 V (16 parts), 6.3 V (14) and 4 V (2); the 9 X7R rows are 10 V (7) and 25 V (2). Above 10 nF every X5R part is 6.3 V or lower, apart from the single 10 V, 100 nF row discussed below. A board that wants 100 nF at 10 V or more in this case has no clean row in the export. We have not seen the dielectric ceiling counted anywhere.
Why is one 100 nF row different from the other four?
Because its dimensions are missing. We read the L, W and T columns on all 317 rows: 313 carry 0.40, 0.20 and 0.20 mm with tolerances, and 4 are blank, 01R5X104K100 among them, with the other three being 01R5N150G160, 01R5N120G500 and 01R5N3R3A250.
The four blank rows sit together near the end of the series and are the only ones without dimensions, so the footprint of the 10 V, 100 nF part cannot be read from the export. We assume it is the same body as its neighbours, but that is an assumption, not a field. The Tolerance column also reads “+-0.05” with no unit on 3 rows, where the other 29 at that tolerance read “+-0.05pF”.
What does the Hong Kong shelf hold in ultra-small MLCC?
None. Of the 1,125 distinct part numbers on our stock list as at 23 September 2026, 0 are among the 317 parts of the 01R5 series, although the list holds 732 MLCC and 132 specialty MLCC in other series.
So every part in this post is a to-order enquiry. The ready-stock list is a dated snapshot, never live-synced, and the MLCC range lists the families. We give no lead time and no stock promise.
What will we not tell you about Brazilian consumer electronics?
Anything about your handset, your platform or your supply plan. Of the 24,026 MLCC rows we hold, the 317 in the 01R5 series have no datasheet in our files, so every count here is catalogue coverage, not suitability for a phone, a wearable or any rail.
We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Brazil; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or conformity advice; confirm with your compliance team. Qualification stays with you.
Why do buyers in Brazil choose Venatech?
Because we show the gaps in the smallest case. Venatech Limited is an authorised Walsin distributor in Hong Kong, and the Walsin 01R5 series is 317 part numbers, 5 at 100 nF, 9 in X7R and 4 with no dimensions, so a Brazilian buyer sees the edges before a layout is frozen.
A Brazilian buyer gets a Hong Kong team that welcomes small lots, answers cross-reference questions field by field, and says plainly when a row cannot be confirmed from the export. Our VenaMatch tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and every candidate comes back with each field marked match or mismatch.
How can Venatech help a Manaus electronics maker?
How Venatech helps starts with a free paste box. The cross-reference tool accepts up to 500 part numbers or an Excel or CSV file and shows Walsin candidates with each field marked match or mismatch. Load a whole BOM for a check. The ready-stock list is a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 100 nF, X5R, plus or minus 10 percent, 6.3 V brief returned 1 exact part among 5 candidates at the value, none stocked. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, we help cross-reference, and you request a quote through the site.
The short version
For a Brazilian phone or wearable maker, 100 nF in the smallest case is a voltage and tolerance question: 5 of 317 Walsin 01R5 parts reach it, X7R stops at 1 nF, and the shelf holds none. Name the dielectric, the voltage and the tolerance.
Send us one 01005-class capacitor line from your BOM, with the dielectric, voltage and tolerance you can accept, and we will return the Walsin parts with every difference stated. If your incumbent is 100 nF at 10 V in the smallest case, do you know that only one Walsin row claims it, and it has no dimensions?

Frequently asked questions
What did Agencia Gov report about the Manaus Industrial Pole in 2026?
On 14 October 2026 it reported revenue of 165.12 billion reais, about 31.98 billion US dollars, for January to August 2026, up 10.47 percent, with 7,988,490 mobile phones made, up 9.22 percent. These are the agency’s figures, not ours.
How many Walsin 01005-class capacitors reach 100 nF?
5 of the 317 parts in the 01R5 series, all X5R: two at 4 V, two at 6.3 V and one at 10 V. X7R in the same series stops at 1 nF, and NP0 stops at 220 pF.
Which Walsin capacitor matches a 100 nF, X5R, 6.3 V, plus or minus 10 percent brief?
01R5X104K6R3 matches on dielectric, value, tolerance, voltage and the 0.40 by 0.20 mm body in the export. Its neighbours differ in tolerance or voltage. Confirm against the datasheet and qualify in your own circuit, including capacitance under DC bias.
Why does 01R5X104K100 have no dimensions?
Its L, W and T cells are blank in the Walsin export, as are those of three other 01R5 rows. The body size cannot be confirmed from the export, so take it from the datasheet for the exact part number before a footprint is drawn.
Are Walsin 01R5 capacitors on the Hong Kong shelf?
Not as at 23 September 2026: 0 of the 317 parts in the series are among our 1,125 stocked part numbers. The snapshot is dated, not live, so ask us through the site for a to-order enquiry.
Do you hold stock or an office in Brazil?
