4mH 1.5A Through-Hole Ferrite Common Mode Choke | 15x7.5x18mm | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics

Mn-Zn ferrite common mode chokes are widely used as EMI suppression components in cost-sensitive and high-volume applications. This compact 15x7.5x18mm through-hole package is well suited for home appliances, routers, consumer electronics, and small communication devices. With stable attenuation in the 100kHz–1MHz frequency range, it effectively reduces switching noise and helps products meet global EMC compliance standards without adding unnecessary cost or size.

This model delivers 4mH inductance and 1.5A rated current, making it ideal for small to medium power supplies. The Mn-Zn ferrite core is sourced from qualified suppliers to ensure stable magnetic characteristics, avoiding parameter drift that can compromise EMI filtering in low-cost alternatives. Every unit undergoes 100% Hipot testing and full electrical inspection to guarantee insulation safety and consistent electrical performance. For long-term reliability, we use automated winding technology to ensure consistency, while copper wire is supplied by world-leading manufacturers, providing excellent insulation integrity and reducing the risk of short circuits during prolonged high-temperature operation.

For routers, household devices, adapters, or compact control units that require reliable EMI suppression at up to 1.5A, this Mn-Zn ferrite common mode choke offers a cost-effective yet dependable solution.
