BIDRAGON Nanocrystalline Common Mode Choke Core

Date: Jul 31st, 2022
Common mode choke coils are often used in computer switching power supplies to filter common mode electromagnetic interference signals. The common mode inductor is essentially a two-way filter. In the design of the circuit board, the common mode inductor also plays the role of EMI filtering, which is used to suppress the electromagnetic waves radiated by the high-speed signal lines.
BIDRAGON company's Nanocrystalline common mode choke core can not only filter out common mode electromagnetic interference on the signal line, but also suppress its own emission of electromagnetic interference, and will not affect the normal working electromagnetic environment of other electronic equipment in the same area.
Common Mode Choke Core
We will provide nanocrystalline CMC iron cores suitable for customers according to the frequency band and impedance frequency curve required by customers. When the coil flows through a large instantaneous current, the magnetic core will not be saturated, and it is ensured that no breakdown and short circuit will occur between the coil turns under the action of instantaneous overvoltage. At the same time, we reduce the parasitic capacitance of the coil and improve the ability of the coil to withstand transient overvoltage.
