Import Dc-Link,Pfc Applications Metallized Polypropylen — Buy in Bulk from Supplier in China

The DC‑Link,PFC applications metallized polypropylene capacitor is offered by Dongguan Kwoktran Electronics Technology Co., Ltd, based in the Huangkeng Industrial Zone of Dongguan, China. It is engineered for DC‑Link and power‑factor‑correction circuits where high voltage and low loss are critical. The capacitor features a metallised film construction that provides high voltage capability, low equivalent series resistance and stable performance across a wide temperature range. According to the supplier, the design delivers a long service life, reducing the need for frequent replacement.

Metallised polypropylene is a standard dielectric for high‑frequency power conversion, offering typical voltage ratings between 2 kV and 6 kV and capacitance values from 1 µF up to 100 µF. Typical ESR values for this class of component are below 0.1 Ω, which helps improve overall efficiency of power supplies. The material maintains its characteristics from - 40 °C to +125 °C, matching the thermal demands of renewable‑energy inverters and electric‑vehicle chargers. Industry practice also calls for compliance with ISO 9001 and CE marking, which the supplier references.

Typical buyers include OEMs of power supplies, solar‑panel inverters and electric‑vehicle charging stations that require reliable DC‑link filtering. The supplier mentions flexible minimum order quantities and indicates that shipments can be arranged under common Incoterms such as FOB or CIF, but exact terms should be confirmed directly. Prospective purchasers should request the supplier’s test reports to verify voltage rating, ESR and lifetime performance. Confirm any certification numbers and packaging details before finalising the contract.

Dongguan Kwoktran Electronics Technology Co., Ltd operates from Huangkeng Industrial Zone, Shilongkeng Liaobu, Dongguan, Guangdong, China (postal code 52300). The company is listed as an imported tier supplier with a harbour‑level trust rating on the platform, indicating that its trade credentials have been verified. Current platform data shows a response rate of 0 % and no recorded average response time, so buyers should anticipate the need for proactive communication.

The supplier’s catalogue includes metallised polypropylene capacitors designed for DC‑Link and PFC applications, as described in the product listing. While the listing notes flexible MOQ options and compliance with ISO and CE standards, exact order quantities and lead times are not disclosed and must be agreed with the supplier. No additional information about production capacity or previous client references is provided.
