KEMET SPST Through Hole Reed Switch 100 mA 30 V dc OHD5R-125B

KEMET OHD5R-125B is a Single Pole Single Throw (SPST) Through Hole Reed Switch designed for reliable switching operations in a wide range of electronics and electrical applications. It supports a maximum switching current of 100 mA and a voltage of 30 V dc, with a maximum power rating of 1 W, making it suitable for low power signal switching and control circuits.

This reed switch features low contact resistance of 300 milliohms, improving conduction efficiency, and is constructed with a Nickel Iron Alloy contact material for enhanced durability and long operational life. It is designed for through-hole mounting with wire terminals, enabling secure and straightforward integration onto printed circuit boards.

The switch operates reliably over a broad temperature range from -20°C to 150°C, making it suitable for industrial, laboratory, and commercial use cases. Its compact size with dimensions of 5 mm width, 6.7 mm length, and 19.1 mm depth supports space-constrained applications.

KEMET’s OHD Thermal Guard series incorporates proprietary technology with a magnet and a temperature-sensitive soft ferromagnetic material, Thermorite®, which changes magnetic flux density with temperature changes, providing thermal protection functionality.

This reed switch is RoHS compliant and manufactured in Japan, assuring high reliability and environmental compliance. Typical applications include atmospheric temperature detection, overheating monitoring for power transistors and modules, room heaters, amplifiers, motors, hard drives, and various other electrical appliances.

The contact configuration is Single Pole Single Throw (SPST) for reliable switching. Maximum switching current is 100 mA with 30 V dc voltage rating. Maximum switching power rated at 1 W. Low contact resistance of 300 milliohms ensures efficient conduction.
