230uH 16A Mn-Zn ferrite common mode choke with center-post air gap design for adjustable inductance | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics
This 230uH 16A common mode choke is designed for power systems that prioritize high current capability and thermal stability. Built with a gapped Mn-Zn ferrite core, it supports applications where noise suppression must remain consistent even under heavy load conditions. The 27.5 × 25 × 10.4 mm form factor makes it suitable for compact control units, high-power driver circuits, and industrial platforms that require dependable common-mode filtering without sacrificing available current headroom.
To support higher operating current, this version uses a reduced inductance value, resulting in a lower overall impedance profile compared with higher-uH variants. Even with the lower Z characteristics, it still provides meaningful wideband attenuation—about 26 dB at 2 MHz and around 21 dB at 100 MHz—making it effective for suppressing common-mode interference across mid- to high-frequency bands. The optimized air-gap design ensures stable magnetic performance under high load and minimizes inductance drift during heavy current operation.
With its 16A current rating and balanced Mn-Zn ferrite structure, this common mode choke is well-suited for power supplies that demand stronger thermal headroom and stable EMI control. It helps manage conducted noise in switching stages, LED lighting systems, and compact industrial controllers where higher current throughput is required. The controlled leakage inductance also enhances differential-mode filtering, providing a dependable solution for designs that need a practical mix of high-current capability and mid-band EMI suppression. Coilmaster Electronics is a high-current 230uH 16A Mn-Zn ferrite common mode choke with center-post air gap design for adjustable inductance, 230uH 16A Air-gapped Mn-Zn common mode inductor optimized for adjustable inductance and high-current EMI filtering manufacturer from Taiwan since 1995. Coilmaster offers AEC-Q200 certified, high-efficiency power inductors, chokes, and transformers. Specializing in low-loss, high-current components for Automotive, 5G, and Industrial applications.
