Common Mode Core

Short Description:

Common Mode Core reduce the common mode noise that is problematic in differential transmission. We can offer EMC Nanocrystalline Core solution for replacing the ferrite. Our EMC Core are very much advantageous in EMC filters for applications with a high amount of asymmetric interference current compared to the established Ferrite materials. Common mode chokes are utilized as a part of request to channel basic mode electromagnetic impedance (EMI) streams without de-rating under high ebbs and flows and without causing signal corruption.

Characteristics

● High initial permeability has bigger insertion loss compared to ferrite and the inhibiting effect is far larger to weak interference than ferrite;
● higher inductance can be obtained with smaller size magnetic core and less coils;
● High saturation magnetic induction intensity (Bs = 1.2 T), strong anti-saturation W;
● Fine frequency and resistance value are higher than with ferrite;
● High Curie temperature, good temperature stability;
● Outstanding unbalanced current resistance;
● Low eddy-current loss, low temperature rise.
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
