OHD3-50B

The OHD3-50B from KEMET is an OHD™ series thermal guard. The OHD™ series thermal guard is developed for thermal problem counter measures and safety standard conformity which are becoming increasingly important for electronic devices in recent years. Typical applications include atmospheric temperature detection and overheating monitoring of power transistors, power modules, room heaters, hot gas heaters, PPCs, amplifiers, motors, HDDs, FDDs and other general appliances.
