Littelfuse POLY-FUSE Resettable PTCs - 1812L Series

The Littelfuse 1812L series PTC provides surface mount overcurrent protection for applications where space is at a premium and resettable protection is desired.

Surface Mount Technology

Resettable fuses are designed for the protection of electrical and electronic circuits against excessive currents. They switch rapidly from a low resistance to very high resistance state under electrical overload or short circuit conditions, and feature automatic reset and return to low resistance state when fault condition ceases and power is removed.

Maintenance free automatic reset for thousands of cycles

Small size and no fuseholder required

Main applications

Security systems

Power supplies and transformers

Power switching devices

Automotive and medical equipment

Instrumentation and control

Computers and peripherals

Audio visual and telecommunications
