One world. One KEMET

Benets

• Extremely simple circuit design

• High reliability for on/off operations

• Compatibility with extremely low (0.1 mW or lower) signals

to high power (6 W) levels

• Compact, light and easy to handle

• Dust, explosion and corrosion-proof

• High-speed response

• Wide range of operating temperatures available in 5°C

increments from +30°C to +120°C

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.

Applications

Typical applications include atmospheric temperature

detection and overheating monitoring of power transistors,

power modules, room heaters, hot gas heaters, PPCs,

ampliers, motors, HDDs, FDDs and other general

appliances.
