20mH 0.5A Compact Ferrite Common Mode Choke | THT Mounting | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics

Mn-Zn ferrite common mode chokes are widely used for EMI suppression in precision electronics and cost-sensitive designs. Our 20mH / 0.5A through-hole choke, offered in a compact 15x7.5x18mm THT package, is specifically suited for instrumentation, metering devices, and small industrial control circuits. With its high inductance value, it delivers strong attenuation in the 100kHz–1MHz range, reducing switching noise and enabling stable EMC compliance for sensitive applications.

To guarantee consistency, the Mn-Zn cores are sourced from qualified suppliers with stable magnetic parameters, avoiding variations that could compromise filter performance. Each unit is 100% tested with Hipot and full electrical inspection, ensuring insulation safety and predictable behavior. For durability, we utilize automated winding processes for coil consistency, and copper wire from world-leading manufacturers to secure insulation integrity under prolonged high-temperature operation.

For projects that require reliable EMI suppression in precision circuits operating at 0.5A or below, this Mn-Zn ferrite common mode choke offers a cost-effective yet dependable solution.
