 ER Core

Based on innumerous times of experiments, we successfully find over 10 types of raw materials that are suitable for making Ferrite Core and develop more than 900 types of ferrite core that have different shapes and specifications.

Application
Drive transformers, high-frequency transformers, power inductors, high-frequency choke coils
One outstanding advantage of the electroFerrite Core lies in the utilization of high-temperature low-consumption material and high magnetic permeability material, which ensure an ultra-low power loss at a high temperature.
To better service our most-valued customers, we can also customize smaller-size ferrite cores. Please feel free to let us know about your requirements.

Packaging
Before leaving the factory, all magnetic products must be well packed to avoid any possible breakage or damage. Additionally, the packaging manner can also be decided by customers.
