OHD5R Datasheet | KEMET

Thermal Sensors OHD Thermal Guard Overview The OHD Thermal Guard is developed for thermal problem countermeasures and safety standard conformity, which are being 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, FDDs and other general appliances. Benefits - High reliability for on/off operations - High-speed response - Long operational life - Excellent environmental durability - patibility with extremely low (0.1 m W or lower) signals to high power (6 W) levels - Extremely simple circuit design - pact, 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 - Ro HS/REACH pliant OHD1 OHD3 © KEMET Electronics Corporation - KEMET Tower - One East Broward Boulevard Fort Lauderdale, FL 33301 USA - 954-766-2800 - .kemet.
