1mH 3A Mn-Zn Common Mode Choke | 17.5×13×22mm THT Ferrite Filter | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics

Designing medium-power supplies and industrial controllers often requires robust EMI solutions, and Mn-Zn ferrite common mode chokes offer a practical answer. Our 17.5×13×22mm model with 1mH inductance and 3A rated current is optimized for home appliances, LED lighting systems, and automation equipment, delivering reliable EMI suppression while maintaining cost efficiency.

This 1mH / 3A through-hole Mn-Zn choke provides stronger current capability compared with smaller variants, making it ideal for applications where low DCR and thermal stability are essential. The Mn-Zn ferrite core is carefully sourced from qualified suppliers to ensure tight parameter consistency, minimizing variation that could affect EMI compliance in high-volume production. Each choke undergoes 100% Hipot and complete electrical performance testing, guaranteeing insulation safety and consistent inductance values.

For durability, the choke is produced using automated coil winding technology to ensure uniform geometry and stable performance. In addition, high-grade copper wire from global suppliers provides reliable insulation and reduces the risk of breakdown during extended high-temperature operation. For customers with special requirements, we also offer customization options, including adjusted inductance, current ratings, or impedance peak tuning to match specific converter or inverter designs.

For home appliances, industrial controllers, or medium-power supplies requiring higher current EMI suppression with a cost-effective ferrite solution, our 1mH / 3A Mn-Zn common mode choke (17.5×13×22mm) delivers an excellent balance of size, performance, and reliability.
