For solar inverter electronics in Turkey, 126 of the 367 safety disc capacitors in the Walsin Technology (Walsin) export print 1500 Vdc in their rating, and all 126 have a 5 or 7 as the third character of the part number; none of the other 241 does. The export does not say what the 1500 Vdc means. None is on the shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a Turkish solar inverter maker, in Istanbul or elsewhere, who is choosing an X1/Y2 capacitor for a grid-side EMI filter. It comes from the Walsin disc capacitor export (929 rows, 929 distinct part numbers, 367 of them safety parts) and our stock list as at 23 September 2026. Every part number is real. Market facts name their source and the day we fetched it, 10 November 2026.
What did Turkish sources report on solar capacity and inverter production in 2026?
Capacity kept climbing and a large inverter maker said it would build more locally. According to Hurriyet Daily News on 22 March 2026, citing the Energy Ministry, Turkey’s installed solar capacity reached 25,827 MW at the end of January 2026, 20.9 percent of all installed electricity capacity, from 40.2 MW in 2014.
On 27 April 2026 Daily Sabah, citing Anadolu Agency, reported that Huawei plans to expand solar inverter production in Turkey through a local partnership, adding capacity and new models; the article gave no megawatt figure, partner name or date. Those are the publishers’ reports, not ours. We have no relationship with Huawei or any Turkish maker and say nothing about what any of them buys.
Which Walsin 100 pF X1/Y2 disc capacitors cross a 1500 Vdc brief, and what differs?
Seven sit in the family, and three match the brief. We filtered the 367 safety parts to 100 pF, Y5P, plus or minus 10 percent in the X1/Y2 AC family and found 7 part numbers; exactly 3 print 1500 Vdc and X1/Y2 together, so exactly 3 match an X1/Y2, 100 pF, 1500 Vdc brief on every export field.
Put your incumbent in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
YP7AC101K060 |
Safety disc, AC series Auto, Y5P, 100 pF, plus or minus 10 percent, X1-440 Vac / Y2-300 Vac, 1500 Vdc | No | Match on class, value, dielectric, tolerance and the 1500 Vdc text | |
YP5AC101K060 |
Safety disc, AC series 500 V, Y5P, 100 pF, plus or minus 10 percent, X1-500 Vac / Y2-500 Vac, 1500 Vdc | No | Match on the electrical fields; mismatch: X1 and Y2 ratings are 500 Vac, higher | |
YP5AC101K050 |
Safety disc, AC series 500 V small size, Y5P, 100 pF, plus or minus 10 percent, X1-500 Vac / Y2-500 Vac, 1500 Vdc | No | Match on the electrical fields; mismatch: small-size variant, 500 Vac ratings | |
YP1AC101K060 |
Safety disc, AC series, Y5P, 100 pF, plus or minus 10 percent, X1-440 Vac / Y2-300 Vac | No | Mismatch: no 1500 Vdc text | |
YP0AC101K060 |
Safety disc, AC series, Y5P, 100 pF, plus or minus 10 percent, X1-440 Vac / Y2-250 Vac | No | Mismatch: no 1500 Vdc text and Y2 rating is 250 Vac | |
YP5AH101K060 |
Safety disc, AH series 500 V, Y5P, 100 pF, plus or minus 10 percent, X1-500 Vac / Y1-500 Vac, 1500 Vdc | No | Mismatch: Y1 class, not Y2 |
A match in the table is a match on the export fields, no more. Confirm against both datasheets and qualify in your own circuit. Our guide to X1/Y1 versus X1/Y2 safety capacitors explains the classes.
How does the part number show which capacitors print 1500 Vdc?
Through the third character. We read the third character of all 367 safety part numbers against the rating text: the digit 5 appears on 103 parts and the digit 7 on 23, and all 126 print 1500 Vdc; the digits 0 and 1 appear on the other 241 parts, and none prints it.
By series, the 126 split into 37 Y1 and 17 small-size Y1 parts in the AH 500 V lists, 13 and 36 Y2 parts in the AC 500 V lists, and 23 in the AC Auto list, which is the only 1500 Vdc list built on the 440 Vac X1 and 300 Vac Y2 pair. Capacitance runs from 10 pF to 4,700 pF in the 500 V lists and from 100 pF to 10,000 pF in the Auto list. Dielectric across the 126 is 42 SL, 33 Y5P, 30 Y5U and 21 Y5V. We have not seen this character-to-rating link counted anywhere.
What does the 1500 Vdc text not tell you?
It does not say what it is. We read the Rated Voltage cell on all 126 parts, and in each case 1500 Vdc is appended to the AC pair with no label, so the export cannot tell us whether it is a working limit, a test voltage or a rating for a particular placement.
A designer with a high DC bus will notice the number; that is the reason to ask for the datasheet, not to assume. The export also lists Y2 at 500 Vac on 49 parts, where the other Y2 parts stop at 300 Vac, and it gives no lead spacing, packing or temperature characteristic on any of the 367 rows.
What does the Hong Kong shelf hold in safety disc capacitors?
None. Of the 1,125 distinct part numbers on our stock list as at 23 September 2026, 0 are among the 367 safety disc parts; the 3 safety capacitors we hold are a different family, and the list holds 732 MLCC, 132 specialty MLCC and 254 chip resistors.
So every disc part in this post is a to-order enquiry. The ready-stock list is a dated snapshot, never live-synced, and the disc capacitor range lists the families. We give no lead time and no stock promise.
What will we not tell you about Turkish solar inverters?
Anything about your topology, your grid code or your safety approval. Of the 367 safety disc parts, none has a datasheet in our files, so every count here is catalogue coverage, not suitability for a grid-connected inverter or any placement.
We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Turkey; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or conformity advice; confirm with your compliance team. Qualification stays with you.
Why do buyers in Turkey choose Venatech?
Because we show what the export cannot say. Venatech Limited is an authorised Walsin distributor in Hong Kong, and the Walsin safety disc range alone is 367 part numbers, 126 of them printing 1500 Vdc, with the rating readable from the third character of the part number.
A Turkish buyer gets a Hong Kong team that welcomes small lots, answers cross-reference questions field by field, and says plainly when a rating text needs the datasheet. Our VenaMatch tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and every candidate comes back with each field marked match or mismatch.
How can Venatech help a Turkish inverter maker?
How Venatech helps starts with a free paste box. The cross-reference tool accepts up to 500 part numbers or an Excel or CSV file and shows Walsin candidates with each field marked 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 X1/Y2, 100 pF, Y5P, 1500 Vdc brief returned 3 matching parts among 7 candidates, none stocked. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, we help cross-reference, and you request a quote through the site.
The short version
For a Turkish inverter maker, a Y capacitor is a rating-text question: 126 of 367 Walsin safety disc parts print 1500 Vdc, a 5 or 7 in the part number marks them, and the shelf holds none. Name the class, the Vac pair and the Vdc text.
Send us one safety capacitor line from your BOM, with the X and Y class, voltage pair and approvals you need, and we will return the Walsin parts with every difference stated. If your drawing says 1500 Vdc, do you know whether your incumbent means a working voltage or a test voltage?
