Thermal Sensors OHD Thermal Guard Overview Applications The OHD Thermal Guard is developed for thermal problem countermeasures 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. Its unique proprietary design features a magnet and a temperature-sensing soft ferromagnetic substance called Thermorite(R). The material's magnetic flux density decreases as the temperature increases turning it into a paramagnetic substance at the Curie temperature.

Please contact a KEMET representative if an oscillation is added. * OHD1 and OHD5R are designed for printed circuit board insertion. OHD3 is reed wire soldered type. Export Control For customers in Japan For products which are controlled items subject to the "Foreign Exchange and Foreign Trade Law" of Japan, the export license specified by the law is required for export. For customers outside Japan Thermal Sensors should not be used or sold for use in the development, production, stockpiling or utilization of any conventional weapons or mass-destructive weapons (nuclear weapons, chemical or biological weapons, or missiles), or any other weapons.
