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.
Benefits
• 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
