Supplied in sealed 9x2.5x2.4 mm packages, these normally open SPST reed switches operate with any Littelfuse actuator magnet. Applications include access control, metering, and limit sensing.

Engineered to perform high-speed, high-volume switching with little power loss, these metal-oxide–semiconductor field effect transistors can serve as solar inverters and high-voltage dc–dc converters.

In addition to excellent power absorption capabilities, AEC-Q101–qualified SZ1SMCxxA TVS diodes handle voltage surges up to 16 kV. Applications include vehicles, medical equipment, and power supplies.

Space-saving AF0025 relays provide ideal solutions for protecting combiner boxes and panels against damaging arc flashes. The relays work in ac or dc systems and feature internal failsafe mechanisms.

With a 250kA interrupt rating and 300% minimum breaking capacity, the ESR range (125-630A at 1.5kV Dc) provides ideal overcurrent protection for battery racks, inverters, and dc power applications.

Find the device you need to reliably perform a specific function such as changing lamp intensity, varying the speed of a motor, or managing the temperature of a heater.

Look to Littelfuse when your application demands a compact, long-lived contactor controlled by a thermostats, relay, or push button.
