Low-profile capacitors for Costa Rica are a narrow shelf. Of 3,979 Walsin Technology (Walsin) 0402 capacitors in the export, only 4 state a maximum height of 0.33 mm or less, all in the TT series, all X5R; a 1 µF 6.3 V brief at that height has two Walsin candidates and neither is on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this from the Walsin MLCC export (24,026 rows, 23,601 distinct part numbers) and our stock list as at 23 September 2026. It is for a design or sourcing engineer at a Costa Rican maker of medical, wearable or semiconductor-assembly electronics who is crossing a thin 0402 capacitor. Every part number is real and every count is ours. The trade figures name their source and the day we fetched it, 2 November 2026.
What did Costa Rica’s exports look like in early 2026, and why does it matter to a component buyer?
They grew, with Asia and Europe leading. According to Observador, citing Procomer data, Costa Rica’s exports in January to April 2026 were 7,463 million US dollars, up 7 percent or 493 million, with exports to Asia up 50 percent and to Europe up 15 percent.
Those are the reported figures, not ours. We draw one conclusion, and it is ours: a country that ships medical devices and assembles semiconductors to Asia and Europe builds small, thin products, and a thin product is decided by millimetres of component height. We have no relationship with any Costa Rican maker and say nothing about what any of them buys.
How many Walsin 0402 capacitors state a height of 0.33 mm or less?
Four of 3,979. We parsed the thickness column of the Walsin MLCC export and added each tolerance to its nominal: of 3,979 distinct 0402 part numbers, 4 state 0.30 plus or minus 0.03 mm, a maximum of 0.33 mm, and all 4 are TT-series X5R. A further 42 have no parseable thickness.
We have not seen this counted anywhere. The TT series holds 56 parts in all, mostly 0805 and 1206 at 0.85 mm, and none of the 56 is on our shelf. The four 0402 parts are TT15X105K6R3, TT15X105M6R3, TT15X224K250 and TT15X474K250. Our post on how to read a Walsin MLCC part number explains the TT prefix, and passive component case sizes explains why 0402 names a tiny case.
Which Walsin parts cross a 0402 X5R 1 µF 6.3 V brief at 0.33 mm, and what differs?
Two match the height and four others do not. We filtered the export for 0402, X5R, 1 µF and 6.3 V and found 6 part numbers in three series; only the two TT parts state 0.30 mm, and the stocked part 0402X105K6R3 states 0.50 plus or minus 0.05 mm. The reader’s incumbent goes in the last column.
| Walsin part | Fields from the export | On shelf 23 Sep 2026 | Match / mismatch with a 0402 X5R 1 µF 6.3 V plus or minus 10% brief at 0.33 mm maximum | Your incumbent |

TT15X105M6R3 |
0402, X5R, 1000nF, plus or minus 20%, 6.3Vdc, T 0.30±0.03 | No | Mismatch: tolerance plus or minus 20 percent; height matches | |
0402X105K6R3 |
0402, X5R, 1000nF, plus or minus 10%, 6.3Vdc, T 0.50±0.05 | Yes | Mismatch: height 0.50 plus or minus 0.05 mm, up to 0.55 mm; the one 1 µF 6.3 V part on the shelf | |
0402X105J6R3 |
0402, X5R, 1000nF, plus or minus 5%, 6.3Vdc, T 0.50±0.05 | No | Mismatch: plus or minus 5 percent and up to 0.55 mm | |
SH15X105K6R3 |
0402, X5R, 1uF, plus or minus 10%, 6.3Vdc, T 0.50±0.20 | No | Mismatch: soft-termination SH series and up to 0.70 mm |
A match in the table is a match on the export fields, no more. Confirm against both datasheets and qualify in your own circuit.
What does the Hong Kong shelf hold in thin capacitors?
No part at 0.33 mm, and one near it. As at 23 September 2026 our stock list holds none of the 56 TT-series parts; the nearest 1 µF 6.3 V 0402 line is 0402X105K6R3, which states up to 0.55 mm.
A design that truly needs 0.33 mm is therefore a quote request, not a shelf pick, and we say so before you build the schedule around it. The ready stock list is a dated snapshot, never live-synced. The MLCC range lists the families.
What will we not tell you about medical and semiconductor-assembly electronics?
Nothing beyond catalogue coverage: of the 28 Walsin datasheets we hold, 26 cover MLCC series and 2 cover chip resistors, and none names a medical application, so every count here says what Walsin lists, not what suits your product. We hold no ISO 9001 or IATF 16949 certificate.
We say nothing about your medical or semiconductor-assembly design or your conformity route, and we make no claim that any part suits a medical product. We give no legal, customs or conformity advice; confirm with your compliance team. Qualification stays with you. We hold no ISO 13485 certificate.
Why do buyers in Costa Rica choose Venatech?
Because the Hong Kong shelf is a list you can read before you ask. Our ready-stock list holds 1,125 part numbers as at 23 September 2026, including 764 of the Walsin MLCC part numbers in the export, and we tell you in the same breath which of your parts are not on it.
We are an authorised Walsin distributor in Hong Kong, we serve small lots, and we show the mismatch as plainly as the match. The list is a snapshot, not live. Confirm our authorisation with Walsin; it takes one email.
How can Venatech help a Costa Rican maker of medical or semiconductor-assembly electronics?
How Venatech helps starts with a free paste box. The cross-reference tool decodes 18 manufacturers’ part numbers across 800,000+ crossable parts and shows the Walsin candidates with each field marked match or mismatch. Load a whole BOM, up to 500 part numbers or an Excel or CSV file. The ready-stock list is a Hong Kong snapshot dated 23 September 2026, not live.
Worked example from our own export: the 0402 X5R 1 µF 6.3 V brief returned 6 part numbers in three series, 2 at 0.33 mm, none of those on the shelf. 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. We hold 28 Walsin datasheets, 451 pages, and send them on request. We hold no office, entity or stock in Costa Rica; 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.
The short version
For a Costa Rican maker of thin electronics, height is the scarce field. Only 4 of 3,979 Walsin 0402 capacitors state 0.33 mm or less, and none of the 56 TT-series parts is on our shelf. A 1 µF 6.3 V brief at that height has two Walsin candidates.
Send us one 0402 or 0201 capacitor line from your BOM with the maximum height your board allows, and we will return the Walsin parts with every difference stated. If your incumbent is 0.33 mm, do you know the tolerance behind it?
