Canada announced on 29 October 2026 an equity investment of up to 1.6 billion dollars in Cohere, which committed at least 1.7 billion dollars to Canadian computing infrastructure by 2030. Hot accelerator boards often move from X5R to an X6S capacitor. Walsin lists 127 X6S parts in 23,601, and 3 are on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a hardware or sourcing engineer at a Canadian server, accelerator-card, networking or power-module maker, from Ottawa and Waterloo to Montreal and Vancouver. Walsin Technology (Walsin) is the only line we are authorised for. The Walsin side is our own MLCC export, 24,026 rows and 23,601 distinct part numbers, re-measured on 11 November 2026. Every part number below is real and appears in that export.
What did Canada announce about Cohere and AI compute on 29 October 2026?
A commercial stake tied to domestic compute. The Prime Minister’s Office stated on 29 October 2026 that Canada will make an equity investment of up to 1.6 billion dollars in Cohere, disbursed in stages, and that Cohere has committed at least 1.7 billion dollars to additional computing infrastructure in Canada by 2030.
The release, which we read on 11 November 2026, names NVIDIA, Bell and Schwarz Group as private investors in the round and commits Cohere to at least 1,000 new technical jobs by 2030. It gives no data centre site or megawatt figure. A commentary in The Hub on 3 November 2026 adds that Calgary, Rocky View County, Mississauga and Oakville have proposed or enacted moratoriums on data centre development. These are the sources’ statements, not ours, and we say nothing about what any named company buys.
Why do accelerator and server boards reach for an X6S capacitor instead of X5R?
Temperature. Under the EIA Class II codes, X5R is specified from minus 55 to plus 85 degrees Celsius with a 15 percent capacitance change, while X6S extends the upper limit to plus 105 degrees Celsius with a 22 percent change; boards near a hot processor or regulator can exceed 85 degrees locally.
That trade is the whole decision: X6S buys 20 degrees of headroom and gives back some stability. X7R and X7S reach plus 125 degrees Celsius, but at 0402 and 0603 they reach far lower values. Our post on NP0, X7R and X5R dielectrics explains the code letters. Where you place a part, and whether 85 degrees is enough, is your thermal analysis, not ours.
How many X6S and X7S parts does Walsin list, and in which sizes?
127 X6S and 21 X7S. We counted 127 distinct X6S part numbers and 21 X7S part numbers among 23,601 Walsin MLCC, all in the General Purpose series; X6S runs from 0201 to 1210 and reaches 1 µF in 0201, 10 µF in 0402, 22 µF in 0603 and 100 µF in 0805, 1206 and 1210.
At the small sizes that matter for decoupling under a processor, the dielectric you choose sets the ceiling. We measured the part numbers at 1 µF or more in 0402 and 0603 by dielectric:
| Case size and dielectric | Part numbers at 1 µF or more | Largest value | Example | Match / mismatch against a 10 µF, 0402, 105 °C brief | Your incumbent |
|---|---|---|---|---|---|
| 0402 X5R | 32 | 22 µF | 0402X106M6R3 |
Mismatch on temperature (85 °C) | |
| 0402 X6S | 20 | 10 µF | 0402S106K6R3 |
Match on value, size and 105 °C class | |
| 0402 X7S | 4 | 2.2 µF | Mismatch on value | ||
| 0402 X7R | 3 | 1 µF | Mismatch on value | ||
| 0603 X6S | 23 | 22 µF | 0603S226M6R3 |
Mismatch on size; match on class | |
| 0603 X5R | 69 | 47 µF | 0603X226M6R3 |
Mismatch on size and temperature |
The X6S 10 µF in 0402, 0402S106K6R3, is listed at plus or minus 10 percent and 6.3 V, while its X5R neighbour 0402X106M6R3 is listed at plus or minus 20 percent. Both are 0.50 mm nominal thick in the export.
What does DC bias do to a 6.3 V X6S capacitor on a 0.8 V or 1.8 V rail?
It removes part of the value, and the export cannot tell you how much. Class II capacitors lose effective capacitance as DC bias rises, and small, high-value parts lose the most; our export lists the rated voltage and nominal value only, with no bias curve for any of the 127 X6S parts.
A low core rail sits far below a 6.3 V rating, which helps, but a 4 V rated 0805 at 100 µF, such as 0805S107K4R0, will not hold 100 µF at a 3.3 V rail. Read the bias data before you count placements. Our post on MLCC DC bias and voltage derating shows the method.
What does the Hong Kong shelf hold in X6S and X7S?
Three X6S lines and no X7S. We read the stock list as at 23 September 2026: of its 1,125 part numbers, 3 are X6S, 0201S224K6R3 (220 nF, 0201), 0402S224K6R3 (220 nF, 0402) and 0402S105K6R3 (1 µF, 0402), all at 6.3 V, and 0 are X7S.
So a 10 µF X6S in 0402 is a request, not a shelf pick, while the X5R 22 µF in 0603, 0603X226M6R3, was on the shelf in that snapshot. The ready stock list is a dated snapshot, never live-synced, and we make no lead-time or availability promise.
