OHD5R-30B

OHD5R-30B is a OHD5R thermal guard. It is developed for thermal problem countermeasures and safety standard conformity, which are becoming increasingly important for electronic devices in recent years. Its unique proprietary design features a magnet and a temperature-sensing soft ferromagnetic substance called Thermorite®. The material’s magnetic flux density decreases as the temperature increases turning it into a paramagnetic substance at the Curie temperature. 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.
