For power applications, MnZn-based SMD chokes provide high current handling, strong impedance across low to mid frequencies, and isolation ratings up to 1500–2000 Vrms.

Power-line CMCs use MnZn material for higher inductance and stronger low-frequency suppression, while signal-line CMCs use NiZn cores for GHz-range noise filtering. Coilmaster provides a complete SMD portfolio—ranging from low-DCR power chokes to miniature MM-series signal chokes—allowing designers to select the correct device based on current rating, data rate, EMC environment, and target impedance.
Perfect replacement to TDK / Würth / Bourns
Coilmaster’s SMM power-line SMD common-mode choke series offers pin-to-pin, drop-in replacements for leading brands with superior availability and competitive pricing: SMM4720 → TDK ACM4520; SMM7060 → TDK ACM7060; SMM9070 → TDK ACM9070; SMM1211 → TDK ACM1211; SMM0905 → Wurth 74422 series. These chokes support high current, low RDC, wide impedance ranges, and operation from –40°C to +125°C, including self-temperature rise.
