150uH 20A Wideband common mode choke delivering strong EMI suppression up to 100 MHz | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics
This 150uH 20A common mode choke is designed for high-current environments such as battery management units (BMU), motor-drive control boards, and EV auxiliary power modules, where compact but reliable EMI filtering is required. Its Mn-Zn ferrite core and gapped structure support stable magnetic performance at elevated currents, while the 27.5 × 25 × 11.3 mm package allows easy placement in power-dense automotive and industrial platforms.
Optimized for mid-band noise suppression, this choke offers approximately 22 dB attenuation at 2 MHz and around 18 dB at 100 MHz, providing a balanced filtering profile for switching stages and high-frequency interference. The reduced inductance value—necessary to support its 20A Irms rating—results in a lower overall impedance, but the air-gapped Mn-Zn design ensures stable inductance behavior, improved thermal stability, and predictable EMI control under demanding load conditions.
With its robust high-current capability and controlled leakage inductance, this 150uH common mode choke is well-suited for industrial automation power rails, communication base-station power units, and on-board charger (OBC) auxiliary circuits. The through-hole construction enhances mechanical stability, while the optimized ferrite geometry helps reduce conducted noise in densely packed electronic systems that require reliable operation across varying load and switching frequencies. Coilmaster Electronics is a high-current 150uH 20A Wideband common mode choke delivering strong EMI suppression up to 100 MHz, 150uH 20A High-frequency Mn-Zn common mode choke with extended impedance in the 1–100 MHz band manufacturer from Taiwan since 1995. Coilmaster offers AEC-Q200 certified, high-efficiency power inductors, chokes, and transformers. Specializing in low-loss, high-current components for Automotive, 5G, and Industrial applications.
