2mH 2A Mn-Zn Common Mode Choke | Compact Through-Hole Ferrite Filter | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics

EMI filtering in small and medium-power systems requires components that combine stability with cost efficiency, and Mn-Zn ferrite common mode chokes provide a reliable solution. Our 2mH / 2A model in a compact through-hole 15×7.5×18mm package is well-suited for adapters, home appliances, LED drivers, and small industrial controllers, delivering effective EMI suppression across the 100kHz–1MHz range.

This 2mH / 2A Mn-Zn choke offers higher inductance compared with 1mH variants, making it particularly suitable for designs requiring stronger attenuation under moderate current loads. To ensure consistency, the Mn-Zn ferrite core is sourced from qualified suppliers, maintaining stable magnetic parameters and avoiding variations that could affect EMC compliance. Each unit undergoes 100% Hipot and full electrical testing, guaranteeing insulation safety and dependable long-term operation.

For reliability and manufacturing consistency, the product is produced using automated coil winding equipment, ensuring uniform geometry and repeatable performance. In addition, we use high-grade copper wire from global suppliers with proven insulation durability, reducing the risk of breakdown during extended high-temperature usage. For specialized requirements, we also offer customization of inductance, rated current, or impedance peak tuning, with prototype samples available in short lead times.

For adapters, household devices, or compact industrial power systems requiring 2mH inductance and 2A current handling, our Mn-Zn ferrite common mode choke provides an optimal balance of size, performance, and cost efficiency.
