Safety Disc Capacitor for Air Conditioners in Pakistan: Waves Restarts AC Assembly With 5,000 Kits, and Venatech Supplies 367 Walsin X1/Y1 and X1/Y2 Discs

Waves Home Appliances has restarted air conditioner assembly in Pakistan with a first consignment of 5,000 kits, and every AC control board carries mains safety capacitors. For the safety disc capacitor, Venatech, Walsin’s authorised distributor in Hong Kong, supplies 367 Walsin parts: 181 rated X1/Y1 and 186 rated X1/Y2, from 10 pF to 10 nF.

Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for engineers and buyers at appliance makers and their board suppliers in Lahore, Gujranwala, Faisalabad and Karachi: air conditioners, refrigerators, deep freezers, washing machines and water dispensers. Walsin Technology (Walsin) is the line we are authorised for. The Walsin figures come from our disc capacitor export, Walsin_DiscCap_ALL.xlsx (929 part numbers), which we re-measured on 11 November 2026, and our ready stock list as at 23 September 2026. Every part number below is real.

What did Waves announce for air conditioners in Pakistan?

A restart after four years. Profit reported on 15 June 2026 that Waves Home Appliances told the Pakistan Stock Exchange it had resumed assembly and nationwide sale of air conditioners, starting with 5,000 completely knocked-down kits from China in T1 and T3 models, after import restrictions in 2022 had suspended the line.

The Profit report, read on 11 November 2026, says the company’s refrigerator and deep-freezer lines kept running, and that the AC restart could also revive its washing machine, microwave oven and water dispenser lines. A follow-up Profit report on 22 June 2026 confirmed shipments to the dealer network. These are the company’s statements as reported; the reports do not name a plant city, and we do not suggest any supplier relationship.

Where does a safety disc capacitor sit in an air conditioner?

On the mains side of every board that connects to the wall. In an AC’s indoor and outdoor control boards, X capacitors sit line to line and Y capacitors sit line to earth in the EMI filter, and a Y capacitor also bridges the primary and secondary of the auxiliary power supply, where it must fail open rather than short.

The class decides where a part may go. A Y2 part provides basic insulation; a Y1 part is rated for reinforced insulation, which is why Y1 is the safer choice across a primary-to-secondary barrier that a user could touch through the low-voltage side. Most X1/Y1 and X1/Y2 discs carry both ratings, so one part can also serve an X position. Inverter ACs add a further reason to care: fast switching in the compressor drive pushes more noise back to the mains, so the EMI filter works harder. Our post on X1/Y1 versus X1/Y2 safety capacitors explains the classes.

How many Walsin safety disc capacitors can Venatech supply?

367 distinct part numbers in three families. We counted 367 Walsin safety-certified disc capacitors in our export: 166 X1/Y1 parts in the AH series, 15 X1/Y1 parts in the AS series rated Y1 500 Vac, and 186 X1/Y2 parts in the AC series, 23 of them labelled for automotive use.

By rating, the export lists Y2 parts at 250 Vac (57), 300 Vac (80) and 500 Vac (49), and Y1 parts at 250 Vac (56), 400 Vac (56) and 500 Vac (69). Values run from 10 pF to 10 nF, with the common EMI values of 1 nF, 2.2 nF and 4.7 nF available in both classes.

What should a Pakistani appliance team check before switching?

Class, AC rating, dielectric and approvals. We checked our export for all 367 safety discs: it gives class, AC rating, value, tolerance and dielectric code, while the certificate numbers and approval marks your safety file needs come from Walsin’s datasheet and the certifying bodies for the exact part number.

Three engineering points follow. First, high-mains margin: where supply voltage swings high, a Y1 400 Vac or Y2 300 Vac part gives headroom over a 250 Vac part. Second, dielectric: the export codes these discs YP (Y5P), YU (Y5U) and YV (Y5V); Y5U and Y5V lose more capacitance at temperature extremes than Y5P, which matters in an outdoor unit in summer heat, so check the curve on Walsin’s datasheet. Third, leakage: total Y capacitance to earth sets touch current, and the limit comes from the appliance safety standard you certify to, so confirm it with your compliance team. Our post on disc capacitor temperature coefficient codes explains the dielectric letters.

How can Venatech help a Pakistani appliance maker?

How Venatech helps is to cross a whole mains-side BOM in one pass. VenaMatch at /cross-reference/ decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, returning every field marked match or mismatch, so a safety disc from another brand comes back with its Walsin class, AC rating and value side by side.

Upload a full BOM at /bom/, browse the disc capacitor range, check the dated ready stock list (a snapshot as at 23 September 2026, never live-synced) and request a quote through the site. We serve from Hong Kong in small lots with fast quotes, hold no office in Pakistan, give no legal, customs or conformity advice, and leave qualification with you.

Frequently asked questions

Has Waves restarted air conditioner production in Pakistan?

Per Profit on 15 June 2026, Waves Home Appliances resumed AC assembly and nationwide sales with a first consignment of 5,000 CKD kits in T1 and T3 models.

How many Walsin safety disc capacitors does Venatech supply?

We counted 367 in our export, re-measured on 11 November 2026: 181 X1/Y1 and 186 X1/Y2 parts. Venatech is Walsin’s authorised distributor in Hong Kong.

What is the difference between a Y1 and a Y2 capacitor?

A Y2 capacitor provides basic insulation; a Y1 capacitor is rated for reinforced insulation, so Y1 is the usual choice across a primary-to-secondary barrier.

Is there a Walsin 4700pF Y1 capacitor?

Yes. YU1AH472M130 is 4.7 nF, plus or minus 20 percent, rated X1 400 Vac and Y1 400 Vac in our export. Request a quote; we source it through our authorised Walsin channel.

Which Walsin Y2 capacitor suits 230V appliances?

The AC series at Y2 250 Vac, such as YU0AC102M060 (1 nF) or YU0AC472M120 (4.7 nF); for high-mains margin, the Y2 300 Vac parts such as YV1AC103M140.

Can Venatech guarantee stock of safety disc capacitors?

No. We give no price, lead-time or stock guarantee. Request a quote through the site for current availability.
