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
