DMT Series

Toroidal Output Power Chokes

Coilcraft DMT Series of toroidal power chokes offer high inductance and high current ratings. The toroidal core shape minimizes external magnetic fields, providing EMI shielding from other components. These legacy output power chokes were designed for applications requiring high DC bias current and meet our UL1446 Class B (130°C) insulation system (UL FIle E83628) requirements. The plastic materials meet UL94V-0.

Designed for any application requiring a high DC current bias
