Data centre power electronics for Thailand need bulk capacitors rated above the rail, and the Walsin Technology (Walsin) X5R 10 microfarad line at 16 V or more has 8 part numbers at 0805, 3 on our shelf, and only 3 at 0603, none stocked. Thailand’s BOI approved 7 data centre projects worth over 96 billion baht on 15 January 2026.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a Thai maker or assembler of server power boards, rack power shelves or point-of-load modules. The market statement names its source and the day we fetched it, 10 November 2026. The counts come from the Walsin MLCC export (24,026 rows, 23,601 distinct part numbers) and our stock list as at 23 September 2026, which holds 1,125 part numbers, 764 of them in the MLCC export. We do not know your rail voltage or ripple current. Every part number is real.
What did Thailand’s BOI approve for data centres in January 2026?
It approved seven projects in one board meeting. According to The Nation Thailand on 15 January 2026, the Board of Investment approved seven data centre projects worth over 96 billion baht, including a True Internet Data Centre project at 223 MW of IT load, a GSA project at a combined 120 MW and a Stellar DC project at 25 MW.
Those are the newspaper’s figures, not ours, and an approval is not a build. The point for a component buyer is narrower: server boards, rack power shelves and point-of-load converters sit under every megawatt of IT load, and each carries bulk ceramic capacitors whose voltage rating and case size decide whether a second source exists. We have no relationship with the investors named, and we say nothing about what any of them buys.
Which Walsin X5R 10 microfarad parts clear a 16 V rating at 0805, and what differs?
Eight part numbers clear it, and they differ in tolerance, voltage, height and series. We filtered the Walsin MLCC export for X5R, 0805, 10 microfarad, 16 V or more and found 8 distinct part numbers in 3 series: 6 General Purpose, 1 Low Profile (TT) and 1 Soft Termination (SH).
If your rail is 12 V, a 16 V part leaves little margin and the 25 V and 50 V steps matter. Capacitance falls under DC bias, and we hold no bias curve in the export; our post on MLCC DC bias and voltage derating explains why. The last column is for your incumbent.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with a 10 uF, 16 V, 0805 brief | Your incumbent |
|---|---|---|---|---|
0805X106K160 |
General Purpose, X5R, 0805, 10 uF, plus or minus 10 percent, 16 V, 1.25 plus or minus 0.20 mm | Yes | Match on size, dielectric, value, tolerance and voltage | |
0805X106M160 |
General Purpose, X5R, 0805, 10 uF, plus or minus 20 percent, 16 V | No | Match on value and voltage; mismatch: tolerance is plus or minus 20 percent, wider | |
0805X106K250 |
General Purpose, X5R, 0805, 10 uF, plus or minus 10 percent, 25 V | Yes | Match on the electrical fields; mismatch: voltage is 25 V | |
0805X106K500 |
General Purpose, X5R, 0805, 10 uF, plus or minus 10 percent, 50 V | Yes | Match on the electrical fields; mismatch: voltage is 50 V | |
TT21X106K160 |
Low Profile (TT), X5R, 0805, 10 uF, plus or minus 10 percent, 16 V, 0.85 plus or minus 0.10 mm | No | Match on the electrical fields; mismatch: height is 0.85 mm, lower | |
SH21X106K250 |
Soft Termination (SH), X5R, 0805, 10 uF, plus or minus 10 percent, 25 V | No | Match on the electrical fields; mismatch: termination and voltage; height not stated in the export |
A match in the table is a match on export fields, no more. Confirm against both datasheets and qualify in your own circuit. See how to cross-reference an MLCC for the field-by-field method.
Does a 10 microfarad 0603 option exist at 16 V or more?
Yes, but only three part numbers, and none is stocked. We counted 8 distinct Walsin X5R 10 microfarad part numbers at 0603 across all voltages; 5 are rated 10 V or less, and only 3 reach 16 V or more: 0603X106K160, 0603X106M160 and 0603X106M250.
The four on our shelf at 0603 are 0603X106K100, 0603X106M100, 0603X106K6R3 and 0603X106M6R3, rated 10 V and 6.3 V. A board shrunk from 0805 to 0603 for density therefore loses voltage headroom on the shelf side. We have not seen this ladder counted elsewhere. We also found no 0603 X7R at 10 microfarad in the export at all, so the dielectric swap has no 0603 answer.
What does the Hong Kong shelf hold in this line?
Eight of 25. We found 25 distinct Walsin X5R 10 microfarad part numbers at 0603 and 0805 across all voltages, and our stock list as at 23 September 2026 holds 8: 0805X106K160, 0805X106K250 and 0805X106K500 plus one more low-voltage part at 0805, and the four low-voltage parts at 0603.
Only the three named 0805 parts meet 16 V or more. The ready stock list is a dated snapshot, never live-synced, and it counts part numbers, not pieces; the MLCC range lists the families. If your value, voltage and tolerance are not stocked, ask for a to-order enquiry through the site.
What will we not tell you about Thai data centre power design?
Anything about your topology, your ripple current or your reliability target. We hold 28 Walsin datasheets, 26 of them MLCC, and none names a data centre or server product, so every count here is catalogue coverage, not suitability.
We make no claim that any part suits a server rail, and we hold no AEC-Q200 or other qualification claim of our own. We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Thailand; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or investment advice; confirm with your compliance team. Qualification stays with you.
How can Venatech help a Thai power-board buyer?
How Venatech helps starts with a free paste box. The cross-reference tool, VenaMatch, decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts; it accepts up to 500 part numbers or an Excel or CSV file and marks every field 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 X5R, 0805, 10 microfarad, 16 V brief returned 6 General Purpose part numbers plus 2 specials, 3 of them on the shelf. Venatech Limited is authorised for Walsin only; Stackpole and Viking are lines we supply. We serve from Hong Kong, welcome small lots, and you request a quote through the site.
The short version
Thailand’s BOI approved 7 data centre projects worth over 96 billion baht on 15 January 2026. For the power board, the Walsin X5R 10 microfarad line at 16 V or more has 8 part numbers at 0805 with 3 on our shelf, and 3 at 0603 with none stocked. Name the voltage and height, not just the value.
Send us one 10 microfarad line from your power-board BOM, with the voltage, tolerance and height you accept, and we will return the Walsin parts with every difference stated. If your board moved from 0805 to 0603, did the voltage rating move with it?

Frequently asked questions
What did Thailand’s BOI approve for data centres in January 2026?
The Nation Thailand reported on 15 January 2026 that the BOI approved seven data centre projects worth over 96 billion baht, including True Internet Data Centre at 223 MW of IT load. These are the newspaper’s figures; check the BOI release before quoting.
How many Walsin X5R 10 microfarad 0805 parts are rated 16 V or more?
Eight distinct part numbers in three series: six General Purpose, one Low Profile (TT) and one Soft Termination (SH). They differ in tolerance, voltage and height. Three of the eight, all General Purpose plus or minus 10 percent, are on our shelf.
Is there a 10 microfarad X5R at 0603 rated 16 V or more?
Three part numbers: 0603X106K160, 0603X106M160 and 0603X106M250. None is on our shelf. The four stocked 0603 parts are rated 10 V or 6.3 V. Check the rating against your rail and derating before shrinking the footprint.
Is a 25 V part a drop-in for a 16 V part?
Electrically the 25 V part has the same value and tolerance fields, but it is a different part number and you must confirm bias behaviour and height in your own circuit. Higher voltage is not automatically better; qualification stays with you.
Which of these parts are on the Hong Kong shelf?
As at 23 September 2026: 0805X106K160, 0805X106K250 and 0805X106K500 at 0805, plus four low-voltage 0603 parts. The snapshot is dated, not live, so ask us through the site for current availability.
