Saudi Arabia’s 500 MW, 2,000 MWh Al Khushaybi battery storage project has a contractor, and its converters need high voltage MLCC snubbers. In the Walsin Technology (Walsin) export, a 1 nF, 2 kV brief returns 32 part numbers, and 1206B102K202 sits on 5 rows in 4 heights.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a power conversion system, inverter or BESS integration supplier serving Saudi projects who is crossing a snubber or filter capacitor at 2 kV. On 11 November 2026 we re-read the Walsin MLCC export, 00_ALL_MLCC_parts_combined.xlsx (24,026 rows, 23,601 distinct part numbers), and our stock list as at 23 September 2026. Every part number is real. The project facts are Saudi Gulf Projects’, fetched today.
What was reported about Saudi Arabia’s Al Khushaybi battery storage project?
A contractor award on one of the Kingdom’s first large BESS projects. According to Saudi Gulf Projects on 13 October 2026, Shandong Electric Power Construction Corporation (SEPCO) secured the 500 MW, 2,000 MWh Al Khushaybi battery energy storage system, part of the Group 1-KSB independent BESS project, with the Saudi Power Procurement Company as offtaker.
The report named ENGIE and Haji Abdullah Alireza & Co. as the developer consortium and gave no construction or commissioning dates. Those are the publication’s facts, not ours, and the story is four weeks old as we write. We have no relationship with any party named and say nothing about what anyone buys. Our point is narrower: four-hour storage at this scale is built from many converter cabinets, and each cabinet’s switching stage carries high voltage ceramic capacitors.
Where does a high voltage MLCC sit in a storage converter?
Across the switching devices and in the filters around them. A snubber or Y-path capacitor in a 1,500 V DC-link converter often sits in the 1 nF range at 2 kV or more, and Walsin lists 854 non-safety MLCC part numbers rated 2 kV or more, of which 27 are on our shelf.
We leave the S2 safety series out of that count, because its Rated Voltage column holds a 5000 V impulse figure rather than a working voltage, a defect we have published before. For a snubber the dielectric matters as much as the voltage: NP0 holds its capacitance under DC bias and temperature, X7R does not, and our post on MLCC DC bias and voltage derating shows by how much. The datasheet for this range is 04_Middle_and_High_Voltage.pdf, which we hold; our post on middle and high voltage MLCC, 200 V to 4 kV covers the series.
How far does Walsin NP0 go at 2 kV in each case size?
Not far below 1808. We grouped the NP0 parts rated exactly 2000 V by case: 1206 stops at 390 pF, 1210 at 470 pF, 1808 reaches 2.2 nF, 1812 2.7 nF, 1825 and 2220 4.7 nF, and 2225 10 nF.
| Case | Highest NP0 capacitance at 2 kV | Can it give 1 nF NP0? |
|---|---|---|
| 1206 | 390 pF | No |
| 1210 | 470 pF | No |
| 1808 | 2.2 nF | Yes |
| 1812 | 2.7 nF | Yes |
| 1825 | 4.7 nF | Yes |
| 2220 | 4.7 nF | Yes |
| 2225 | 10 nF | Yes |
So a 1 nF NP0 snubber at 2 kV starts at 1808. A 1206 at 1 nF and 2 kV exists only in X7R. That is a real design choice for a Saudi converter running hot in summer ambient: accept X7R’s loss under bias in 1206, or take the board area for NP0 in 1808.
Which Walsin parts answer a 1 nF, 2 kV brief, and what differs?
Thirty-two part numbers, 8 NP0 and 24 X7R, on 47 rows. We filtered the export for 1 nF at 2000 V and found 47 rows holding 32 distinct part numbers in the Middle to High Voltage, Big Sizes, SH and SG series; the only one on our shelf is the X7R 1206B102K202.

A match in the table is a match on export fields, no more. Confirm against both datasheets and qualify in your own circuit.
Why does one Walsin part number appear on five rows?
Because the export lists each thickness variant as its own row under one code. We read the five rows for 1206B102K202: they give 1.25, 1.60, 0.95 and 0.80 mm thickness and one blank, with thickness symbols D, G, C, B and C, and three carry a customised-product remark spelled three different ways.
Across all 1,019 part numbers rated 2 kV or more, we found 59 that appear on more than one row, 52 of them outside the S2 series. We have not seen this counted anywhere. For a Saudi buyer it means the part number on a purchase order does not fix the height, and three of the five 1206B102K202 variants are marked as customised, which usually means a separate conversation with the maker. State the thickness and ask which variant a lot carries; we can tell you which one is on our shelf before you commit.
What does the Hong Kong shelf hold at 2 kV and above?
Twenty-seven lines, one in this brief. Our stock list as at 23 September 2026 holds 1,125 part numbers; we counted 68 of the 1,874 MLCC part numbers rated 1 kV or more on it, 27 of the 854 non-safety parts rated 2 kV or more, and 1 of the 32 in the 1 nF, 2 kV brief.
The ready stock list is a dated snapshot, never live-synced, and it counts part numbers, not pieces. For an NP0 line in 1808, ask for a to-order enquiry by exact part number and thickness; we make no lead-time or stock promise. We hold no office, entity or stock in Saudi Arabia; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no customs, localisation or legal advice; confirm with your compliance team. The MLCC range lists every family.
How can Venatech help a Saudi storage-converter 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; paste up to 500 part numbers or drop an Excel or CSV file and every field comes back marked match or mismatch. Load a whole BOM for a check, and see the ready-stock list, a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 1 nF, 2 kV brief returned 32 part numbers on 47 rows, 1 exact NP0 match in 1808, and 1 X7R part on the shelf with four heights behind one code. 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. Qualification stays with you.
The short version
SEPCO won the 500 MW, 2,000 MWh Al Khushaybi BESS, Saudi Gulf Projects reported on 13 October 2026. For the high voltage MLCC in its converters, 1 nF NP0 at 2 kV starts at 1808 in the Walsin export, and the one 1206 X7R part we stock sits on 5 rows in 4 heights, so name the thickness on every order.
Send us one snubber or filter capacitor line with the voltage, dielectric and height you need, and we will return the Walsin parts with every difference stated. Does your purchase order say which thickness of a high voltage MLCC you expect?

Frequently asked questions
Who won Saudi Arabia’s Al Khushaybi battery storage contract?
Saudi Gulf Projects reported on 13 October 2026 that SEPCO secured the 500 MW, 2,000 MWh Al Khushaybi BESS, part of the Group 1-KSB project, with SPPC as offtaker and ENGIE and Haji Abdullah Alireza & Co. as developers. These are the publication’s facts.
What is the smallest Walsin case for a 1 nF NP0 capacitor at 2 kV? In the export, NP0 at 2000 V stops at 390 pF in 1206 and 470 pF in 1210, while 1808 reaches 2.2 nF; 1808N102J202 matches a 1 nF, plus or minus 5 percent brief. Confirm against the datasheet. Why does 1206B102K202 appear five times in the Walsin export?
Each row is a thickness variant under one part number: 1.25, 1.60, 0.95 and 0.80 mm plus one blank, with three rows marked as customised products. State the thickness on the order and ask which variant a lot carries.
How many Walsin high voltage MLCC are rated 2 kV or more?
We counted 1,019 part numbers rated 2 kV or more, or 854 if the S2 safety series is excluded, because its 5000 V reading is an impulse rating. Fifty-nine of the 1,019 appear on more than one row.
Does Venatech stock 2 kV MLCC in Hong Kong?
Yes, some. The snapshot dated 23 September 2026 holds 27 of the 854 non-safety part numbers rated 2 kV or more, including 1206B102K202. It is a dated snapshot, not live stock; ask through the site for current availability.
Do you have an office or stock in Saudi Arabia?
No. We hold no office, entity or stock in Saudi Arabia; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen. We hold no ISO 9001 or IATF 16949 certificate and give no customs or legal advice. Confirm with your compliance team.
