Product Description
Nanocrystalline Toroidal Cores for Common Mode Chokes
Nanocrystalline Toroidal Cores for Common Mode Chokes feature High permeability,High indutance,easy help you treat EMI problems.
Fe-based nanocrystalline core features very high permeability, high saturation flux density, low loss makes common mode choke has large inductance with only a few turns, low copper loss and small size.
We are professional producer of amorphous core and nanocrystalline core.
Introduce:
It is well known that the higher CT core permeability, the lower measurement error & higher measurement accuracy. The silicon steel CT core can't get enough measurement accuracy under the situation of low Ampere-tums or small turn ratios. And the Fe-Ni Perm-alloy core's application is limited because of their low magnetization and high cost. Nano-crystalline cores are getting wider usage for the 0.2,0.2s, 0.1 accuracy grade precious current transformers because of its high permeability, high magnetization and lower cost in Iow Hc field of power supply systems, power energy measurement and controlling systems, dynamical system, relay protection, etc.
Features:
*High Saturation magnetic induction - reduce transformer volume
* High magnetic permeability low coercive force- improve transformer efficiency, mutual inductor sensitivity, reduce coil distribution parameters
*Low loss- reduce transformer temperature rise
*Good temperature stability - under 130ºC for long-term work
*Lower price - has the best cost performance of all the metal soft magnetic material
