As an MLCC supplier for Malaysia’s data-centre and semiconductor builds, Venatech Limited, an authorised Walsin distributor in Hong Kong, lists 34 Walsin X5R MLCC part numbers from 1 µF to 100 µF as ready stock as at 9 November 2026, including 22 µF in 0402, 0603 and 0805 and 47 µF in 0805 and 1206.
This post is for the hardware engineer, buyer or EMS planner in Malaysia whose boards go into Johor data halls or come out of the semiconductor corridor from Kulim to Penang: servers, storage, network switches, power shelves and test equipment. These boards use high-value X5R MLCC by the thousand. Venatech is the authorised distributor in Hong Kong for Walsin Technology (Walsin). We counted the X5R lines on our Hong Kong ready-stock list as at 9 November 2026 and matched each to Walsin’s parametric data in our catalogue files (Venatech_MLCC_Upload_01.xlsx to Venatech_MLCC_Upload_08.xlsx). We fetched both reports below on 13 November 2026.
How fast are Johor data centres and Kulim semiconductor plants growing?
Fast, on both fronts. The Star reported on 1 September 2026, citing Cushman and Wakefield, that Johor had 1,110 MW of operational data-centre IT capacity in the first half of 2026, with 602 MW under construction and colocation vacancy at 0.7 percent.
In the north, Malay Mail reported on 16 June 2026 that Austrian maker AT&S will invest up to 2 billion euros, about 9.4 billion ringgit, more in Kulim, Kedah, to fit out its Plant 2 structure and build a new facility for integrated-circuit substrate cores and advanced printed-circuit boards, following agreements with AMD and another technology company. Both sets of figures are the publishers’; we say nothing about any operator’s or maker’s suppliers. Together they describe one demand: more boards carrying processors, memory and power stages, each ringed with decoupling capacitors.
Why do data-centre and semiconductor boards in Malaysia use so many high-value X5R MLCC?
Because processors and power stages need low-impedance charge close to the pins. A server board’s point-of-load regulators and processor rails use banks of 10 µF to 100 µF ceramic capacitors at low voltage, and X5R is the dielectric that reaches those values in 0402 to 1210 at 6.3 V to 25 V.
X5R is rated from minus 55 to plus 85 degrees Celsius in Walsin’s data, which fits most board-level positions inside a cooled data hall or an equipment cabinet. Hotter positions need X7R or X6S and a size step up. The 12 V input rails of server power and the 48 V shelves use higher-voltage parts; for those, see our note on building a BOM that survives a shortage, which covers second-sourcing bulk capacitors.
How many Walsin X5R MLCC at 1 µF and above are on the Hong Kong list?
34 of the 57 listed X5R lines. We counted 57 Walsin X5R MLCC part numbers on our ready-stock list as at 9 November 2026; 34 of them are 1 µF or more: 2 in 0201, 7 in 0402, 10 in 0603, 9 in 0805, 4 in 1206 and 2 in 1210, topping out at 100 µF.
Twenty-three of the 34 are on our own Hong Kong shelf; the rest is Walsin stock we can access through our Hong Kong supplier network, and each quote says which. All 34 are in Walsin’s General Purpose series.
| Case size | Walsin X5R lines at 1 µF and above on the list | Highest listed value |
|---|---|---|
| 0201 | 2 | 2.2 µF |
| 0402 | 7 | 22 µF |
| 0603 | 10 | 22 µF |
| 0805 | 9 | 47 µF |
| 1206 | 4 | 47 µF |
| 1210 | 2 | 100 µF |
Which listed Walsin X5R parts match common server and board-level decoupling briefs?
Nine of ten briefs match on every field. We checked ten decoupling and bulk briefs typical of server, storage and test-equipment boards against the list as at 9 November 2026; nine matched a listed Walsin X5R part on size, value, tolerance and voltage, and one matched on value but not voltage, with a larger listed option.

A match is a match on Walsin’s published fields as we read them from our export. Confirm height against your keep-out under heat sinks and DIMM sockets, and qualify any new part in your application before production.
What should a Malaysian engineer check on a high-value X5R MLCC?
DC bias first, then temperature and height. A 22 µF X5R MLCC at 6.3 V can deliver well under its nominal value at its working voltage, so compare Walsin’s datasheet DC bias curve at your rail voltage and count the effective capacitance, not the label, when you size a decoupling bank.
Check, in order: effective capacitance at the rail voltage and temperature; the 85 degree Celsius ceiling against the hottest position; thickness against mechanical clearance; and ripple current where the part sits on a regulator output. For a cross from Murata, Samsung or TDK, paste the incumbent into VenaMatch, which marks each field match or mismatch, and compare the DC bias curves of both makers before you approve. Our article on crossing Samsung MLCC families to Walsin shows the field-by-field method.

The short version
The Star reported on 1 September 2026 that Johor had 1,110 MW of operational data-centre IT capacity in the first half of 2026, and Malay Mail reported on 16 June 2026 that AT&S will invest up to 2 billion euros more in Kulim. For the boards behind both, our Hong Kong list as at 9 November 2026 holds 34 Walsin X5R MLCC lines from 1 µF to 100 µF, and nine of ten typical decoupling briefs matched.
Send us your decoupling and bulk capacitor lines, and we will return the listed Walsin parts with every field difference marked.
