OHD Thermal Guard
Overview
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.
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.
Applications
Typical applications include atmospheric temperature detection and overheating monitoring of power
transistors, power modules, room heaters, hot gas heaters, PPCs, amplifiers, motors, HDDs, F...
