Product Introduction
Ferrite power transformers generally refer to high-frequency transformers composed of magnetic cores sintered from metal oxides such as manganese-zinc (Mn-Zn) or nickel-zinc (Ni-Zn), along with coils. They feature high resistivity, low eddy current loss, and high magnetic permeability, making them particularly suitable for high-frequency applications.
Common models include EE, EI, ER, EPC, ER, ETD, EFD, PQ, and RM types.
Product Features
• High electrical resistivity and low power loss
• Wide operating frequency range
• Compact size and light weight
• Low magnetic flux leakage

FAQ
Q1: What determines the power rating of a ferrite power transformer?
A: Core size and effective cross-sectional area (Aₑ): Larger Aₑ supports higher power output.
Operating frequency: Higher operating frequency allows greater power transmission.
Ferrite material: Conventional PC95 exhibits lower high-frequency loss than PC40, enabling higher power transfer at elevated frequencies.
Circuit topology: Optimized topologies maximize power output for the same core structure.
Q2: How to distinguish ferrite power transformers from silicon steel sheet power transformers?
A: Core structure: Ferrite power transformer cores are generally integrally die-cast, while silicon steel sheet power transformer cores are typically stacked with laminated silicon steel sheets.
Application scenario: Ferrite power transformers are exclusively used in high-frequency circuits, usually accompanied by integrated circuits such as PCBs, MOSFET switches and heat sinks. In contrast, silicon steel sheet power transformers are directly connected to 220V AC mains.
