KEMET SPST Through Hole Reed Switch 300 mA 110 V AC/DC OHD3-75B

KEMET OHD3-75B SPST Through Hole Reed Switch is engineered for dependable switching with a maximum current of 300 mA and voltage rating of 110 V AC/DC. This switch is ideal for low power applications requiring precise contact control.

The Single Pole Single Throw (SPST) contact configuration allows straightforward switching operations including on/off control. Its nickel iron alloy contact material maintains low contact resistance of 150 milliohms, ensuring efficient conductivity and minimizing signal loss.

Designed for easy installation, the switch features tab leads and through hole mounting type. It is compact and lightweight with dimensions measuring 27 mm in length, 13.5 mm in width, and 12.5 mm in depth, suitable for space-constrained electronic assemblies.

This switch operates safely over a broad temperature range of negative 20 degrees Celsius to positive 150 degrees Celsius, providing stable performance in varying environmental conditions. The product complies with RoHS directives, ensuring it meets regulatory requirements for hazardous substances.

One of the defining features is the OHD Thermal Guard series technology incorporating Thermorite®, a proprietary temperature-sensitive soft ferromagnetic substance. This material enables the switch to adjust its magnetic flux density as temperature changes, making it suitable for thermal problem countermeasures and temperature detection in industrial applications.

Typical use cases encompass atmospheric temperature sensing and overheating monitoring of power transistors, power modules, room heaters, motors, amplifiers, hard disk drives, and other general electronics. The switch is dust, explosion, and corrosion-proof, with high reliability for on/off operations and long operational life, supporting both industrial and commercial applications.

The contact configuration is Single Pole Single Throw (SPST) for simple on/off control. Maximum switching power is rated at 6 watts for low power applications. Features nickel iron alloy contact material with 150 milliohm contact resistance.

Equipped with tab leads for easy through hole mounting. Operates reliably within a wide temperature range from -20°C to 150°C. Compact dimensions are 27 mm length, 13.5 mm width, and 12.5 mm depth. Complies with RoHS standards ensuring environmental safety.
