1mH 2A Mn-Zn Common Mode Choke | Compact THT EMI Filter CMT1205B-102N-LF | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics

Mn-Zn ferrite common mode chokes are among the most widely adopted EMI suppression components for cost-sensitive and high-volume applications. This compact 15x7.5x18mm THT package model is well suited for consumer electronics, power adapters, chargers, home appliances, and communication devices. It provides stable attenuation in the 100kHz–1MHz range, effectively reducing switching noise and helping products meet EMC compliance without adding unnecessary cost or bulk.

This choke delivers 1mH inductance with 2A rated current, optimized for small and medium power supplies. The Mn-Zn core is carefully sourced from qualified magnetic material suppliers to ensure consistent parameters, avoiding the performance drift often seen in lower-grade alternatives. Every unit undergoes 100% Hipot testing and full electrical characteristic inspection, ensuring insulation safety and reliable performance. To guarantee long-term stability, we adopt automated coil winding technology for production consistency, and use copper wire from world-leading manufacturers with proven insulation reliability, reducing the risk of breakdown or short circuits during prolonged high-temperature operation.

For compact adapters, household devices, or small-scale industrial control units requiring reliable EMI suppression up to 2A, this Mn-Zn ferrite common mode choke provides a cost-effective yet dependable solution.
