TDK Product Features
Ceramic PTC thermistors protect e.g. the inputs of power supplies from excessive inrush and surge currents caused by charging of capacitors. Applications are inverters of air-conditioners, industrial drives, welding machines, on board chargers, charging and discharging of DC link capacitors in hybrid and electrical vehicles.The components are characterized by their high reliability and the fact that they require only minimal additional design-in effort. The portfolio covers leaded disk versions and PTCs in housing for DC link voltages of up to 800 V.
