Data Center Passive Components for the United States: 23 of 219 Walsin MLCC Rows at 1 uF or More in 0201, 0402 and 0603 Are on the Hong Kong Shelf, 12 of Them at 6.3 V

Data center passive components for the United States are a shelf question as much as a specification question. We joined the 24,026-row Walsin MLCC export to our 23 September 2026 stock list: of 219 rows at 1 uF or more in 0201, 0402 and 0603, 23 are held in Hong Kong, and 12 of those 23 are rated 6.3 V.

Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) parametric exports and a dated stock list of 1,125 part numbers. This post is for a United States power or board engineer on a server, accelerator or power-shelf design who wants to see what small, high-capacitance MLCC a Hong Kong shelf actually carries. Every part number below is real. Every count is ours. The market projection is cited to its publisher, and we claim no part is on any named system’s bill of materials.

What does the EPRI projection say about United States data center power?

EPRI projects United States data centers could consume 9% to 17% of the country’s electricity by 2030, against 4% to 5% today. That range is 60% higher than EPRI’s earlier scenarios, which is why power-delivery passives are now a planning topic for board teams and not only for utilities.

We read the Electric Power Research Institute product page “Powering Intelligence 2026: Updated Scenarios of U.S. Data Center Electricity Use and Power Strategies” on 21 October 2026. The page carries no publication date; its footer reads 2001-2026. It describes Low, Medium and High scenarios for capacity growth through 2030 and gives no terawatt-hour figures. We have not read the full report, and we draw no conclusion about demand for any one maker’s parts. Our view, labelled as ours: more rack power means more converter stages, and every converter stage has input, output and point-of-load capacitors that someone must source.

Point from the EPRI page	What it says	What it means for a component buyer	Match / mismatch
Share of US electricity by 2030	9% to 17%	A planning range, not a forecast of any part	Match for the demand-direction question
Share today	4% to 5%	The baseline the range is measured against	Match for context only
Change from prior scenarios	60% higher	Earlier plans may be under-sized	Mismatch with any assumption that last year’s volumes hold
Component-level content	None on the page	No passive-component demand figure is given	Mismatch: the page cannot tell you what to buy

How many small Walsin MLCC at 1 uF or more are on the Hong Kong shelf?

Twenty-three of 219. We counted every export row (we parsed all 24,026) in X5R, X6S, X7R and X7S at 0201, 0402 and 0603 with a capacitance of 1 uF or more: 219 rows (209 distinct part numbers), and 23 of them match a line in our 23 September 2026 stock list. We have not seen this counted anywhere.

We broke the 23 down by dielectric as 17 X5R, 5 X7R and 1 X6S, and by size as 1 at 0201, 10 at 0402 and 12 at 0603. We tallied the export at 115 X5R rows, 49 X6S, 46 X7R and 9 X7S. The shelf holds none of the 9 X7S rows and 1 of the 49 X6S rows. Our earlier post on power-delivery MLCC at 10 uF and above found that all 29 export parts at 10 uF or more in 0402 and 0603 sit in one series; the shelf view adds that 6 of those 29 are held.

Band	Export rows	Held on 23 September 2026	Match / mismatch against a shelf-first plan
1 uF or more, 0201, 0402, 0603, X5R/X6S/X7R/X7S	219	23	Match for 10.5% of rows
Of which 10 uF or more	29	6	Match for 21%; mismatch for the other 23 parts
Of which rated 25 V or more	46	2	Mismatch for 44 rows
Of which rated 35 V or 50 V	16	0	Mismatch: factory order only

What does the 22 uF, 0603 ladder look like row by row?

Six rows, one on the shelf. The export lists six 0603 parts at 22 uF, all in the General Purpose series, and only 0603X226M6R3 (X5R, plus or minus 20%, 6.3 V, 0.80 plus or minus 0.20 mm thick) is held. The other five differ from it in exactly one or two fields, which is the cleanest way to see what a swap costs you.

Part	Dielectric	Tolerance	Rated voltage	Held 23 Sept 2026	Match / mismatch against a 0603, 22 uF, X5R, plus or minus 20%, 6.3 V incumbent
0603X226M6R3	X5R	plus or minus 20%	6.3 Vdc	Yes	Match on every export field
0603X226M4R0	X5R	plus or minus 20%	4 Vdc	No	Mismatch on voltage: lower
0603S226M6R3	X6S	plus or minus 20%	6.3 Vdc	No	Mismatch on dielectric: X6S, not X5R
0603X226M100	X5R	plus or minus 20%	10 Vdc	No	Mismatch on voltage: higher; check height and DC bias
0603X226K100	X5R	plus or minus 10%	10 Vdc	No	Mismatch on voltage and tolerance

A 22 uF X5R part loses a large share of its capacitance under DC bias, and the export carries no bias curve. Our post on MLCC DC bias and voltage derating explains why a 6.3 V part on a 5 V rail needs the datasheet curve, not the nominal value. We state no derated figure for any part here.

Which voltages and dielectrics does the shelf cover, and which does it not?

Low-voltage X5R, and very little else. Of the 23 held lines, 12 are rated 6.3 V, 6 are 10 V, 3 are 16 V and 2 are 25 V; none is rated above 25 V, while the export has 16 rows at 35 V and 50 V in the same band.

The 4 V band is missing from the shelf too: the export has 16 rows at 4 V in these sizes and none is held. For a rail near the top of a rating, the shelf offers little headroom, so a buyer working to a derating rule of their own should check the 10 V and 16 V lines first. The nearest neighbours in our size and dielectric notes explain why X7R trades capacitance for stability.

The shelf is a dated snapshot and moves. Walsin’s datasheets give the test conditions for the General Purpose series; we hold the General Purpose sheet and send it on request. Whether any of these parts suits a given accelerator rail is a design decision. Qualification stays with you.

What can Venatech support for a United States data center build, and what can it not?

We can cross a line and show a shelf, and we claim nothing beyond that. We hold no system vendor’s approved vendor list, no hyperscaler approval and no qualification report for any of the 23 lines, and the export carries no column for ESR, ripple current or DC bias. Walsin is our authorised line; confirm that with Walsin.

We state no price, lead time or delivery commitment. We hold no office, entity or stock in the United States; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. Duties, export rules and customs are for your compliance team to confirm. Our tariff post reads the United States Section 301 position at source: Section 301 tariff on electronic components.

How Venatech helps

• Cross-reference. Paste an incumbent capacitor into the free cross-reference tool. It decodes 18 manufacturers’ part numbers across 800,000+ crossable parts and lists Walsin candidates with match and mismatch fields.
• BOM check. Load a whole board into /bom/, up to 500 part numbers or an Excel or CSV file, and read each line against the same engine.
• Ready stock. The Hong Kong ready-stock list is a dated snapshot as at 23 September 2026, not live-synced.
• Authorised line. Walsin is the only line we are authorised for. Stackpole and Viking are lines we supply.
• Service. Hong Kong-based, small lots, cross-referencing help, and a quote on request through the site. See the MLCC range.

A worked example from our own export: paste 0603X226M4R0 and the tool shows the 6.3 V and 10 V neighbours at the same size and capacitance, which is the ladder above.

The short version

EPRI’s projection says data center load could be 9% to 17% of United States electricity by 2030. Our contribution is smaller and checkable: 23 of 219 export rows at 1 uF or more in 0201, 0402 and 0603 are on our shelf, 12 at 6.3 V, none above 25 V, and 1 of 6 at 22 uF in 0603. The rest are factory orders.

Send us one decoupling or bulk-capacitor line from your power-stage BOM and we will return the Walsin parts with the differences stated. If the shelf holds the voltage you can use and nothing above it, is your derating rule written around the parts or around the rail?
