7.5mH 2.5A Mn-Zn Common Mode Choke | High Inductance Through-Hole Filter | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics

Designing power supplies and industrial controllers often requires components that can handle higher current while still delivering strong low-frequency EMI suppression. Our 7.5mH / 2.5A Mn-Zn common mode choke in a 17.5×13×22mm through-hole package provides engineers with a reliable solution for industrial electronics, home appliance inverters, LED lighting, and UPS systems, ensuring stable compliance with global EMC standards.

With its 7.5mH inductance and 2.5A rated current, this choke combines higher inductance for enhanced low-frequency attenuation with increased current handling capacity. The Mn-Zn ferrite core is carefully sourced from qualified suppliers to maintain stable parameters, minimizing performance drift across production lots. Every unit is subject to 100% Hipot and full electrical testing, guaranteeing insulation integrity and consistent inductance values for long-term system stability.

To further improve durability, the product is manufactured using automated winding equipment for uniform coil geometry, while high-grade copper wire from global suppliers provides reliable insulation, reducing the risk of breakdown under continuous high-temperature operation. For project-specific needs, we also support customization of inductance, current capacity, and impedance peak tuning, enabling faster adaptation to different power system designs.
