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.

Benefits

• High reliability for on/off operations

• High-speed response

• Long operational life

• Excellent environmental durability

• Compatibility with extremely low (0.1 mW or lower)

signals to high power (6 W) levels

• Extremely simple circuit design

• Compact, light and easy to handle

• Dust, explosion and corrosion-proof

• Wide range of operating temperatures available in 5°C

increments from +30°C to +130°C

• UL, CSA and TÜV approved

• RoHS/REACH compliant

Applications

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.
