EMC CORE

We can offer EMC Core solution for replacing the ferrite. EMI core standard range is specially designed for Common mode filter chokes; i.e. maximum attenuation is achieved with a minimum of core material.
Electronic gadgets produce electromagnetic interferences, which can influence the best possible working of electronic gadgets and frameworks. As the need to guarantee EMC (electromagnetic compatibility) keeps on developing in significance, Catech has built up an extensive variety of items intended to ensure electrical and electronic hardware against EMI (electromagnetic obstruction).


Our Common mode choke core are based on nanocrystalline softmagnetic material nanocrystalline which provide a unique combination of high permeability and low losses at high frequencies. This is why they are suitable for many applications, such as

Common Mode Filter Chokes
Absorber Cores for suppression of Motor bearing currents
High precision Energy Meters
Current Sensors
HF Current transformers

Application

Solar inverters Switched-mode power supplies
Frequency Converter
EMC filters
Welding equipment
Wind generators
Automotive applications
Inductive cooking
Uninterrupted Power Supply(UPS)

Characteristics

High μ,high Bs, easy to design, reduce the core geometry effectively.
Excellent frequency character
Stable temperature character
Excellent impedance character.
Low magnetostriction coefficcident, low noise
