WCM305 Series High Temperature Choke Power Inductor
WCM305 series power inductors are designed to handle high levels of current and are designed for 200°C operation. Using high temperature materials, these power inductors can withstand the full rated RMS current on a continuous basis. All materials are 200°C rated and suitable for high temperature use. The toroidal design places this component in a very cost competitive position and features low EMI as well.
