Import Ferroxcube Ferrite Pt Cores Transformer Cores — Buy in Bulk from Supplier in China

The PT core redesign removes material from one half of a classic P‑core, creating wide wire slots that accommodate stronger coil formers and integrated solder pins. This modification solves the narrow‑slot limitation of traditional P‑cores and enables more robust winding structures. The design remains compatible with most standard P‑core accessories, allowing existing tooling to be reused. The supplier highlights this geometry as a practical improvement for high‑current power applications.

Typical material for PT ferrite cores is MnZn ferrite with a permeability that usually falls between 1500 and 2000. Standard operating frequencies for such cores range from 0.5 to 5 MHz, matching most power‑conversion needs. Typical dimensions extend from 12 mm × 12 mm × 6 mm up to 120 mm × 120 mm × 60 mm, with a dimensional tolerance of ±0.2 mm. Standard bulk packaging is in cardboard boxes up to 25 kg, which protects the cores during handling.

These cores are commonly employed in power supplies, high‑frequency transformers and inverter modules where low loss and reliable winding space are critical. OEMs in the power electronics sector source them to improve efficiency and simplify assembly. While the listing does not state specific trade conditions, the supplier generally offers standard FOB or CIF options and flexible order quantities. Buyers should confirm payment terms such as T/T or LC directly with the seller.

Chen Pei Enterprise Co., Ltd. operates from No.105A, Chonghe Xiatang Village, Qingxi Town, Dongguan, Guangdong 523660, China. The company carries a harbor trust tier, indicating that its business credentials have been validated on the platform. Response metrics show a 0.00% response rate with no recorded response time, so prospective buyers should verify active communication channels before negotiating.

The firm focuses on magnetic components, especially ferrite transformer cores, and offers custom sizes to meet specific engineering requirements. Although the supplier mentions compliance with industry standards, the exact certification numbers are not listed and should be requested. Importers are advised to obtain sample units and test data to confirm performance before placing larger orders.
