Littelfuse 0.14 A 60V DC Resettable Fuse Surface Mount PTC 1812L Series 1812L014DR

The Littelfuse 1812L014DR is a surface mount, resettable PTC fuse specifically designed for protecting electrical and electronic circuits against overcurrent conditions. The product features a hold current of 0.14 A and a maximum operating voltage of 60V DC, making it suitable for compact and sensitive circuit applications. The 1812L series fuse switches rapidly from a low resistance state to a very high resistance state under overload or short circuit conditions and automatically resets when the fault is removed.

Its compact 1812 package size with dimensions 4.73 mm (length) x 3.41 mm (width) x 1.95 mm (height) allows integration in dense circuit board designs. The fuse supports a trip current of 340 mA with a fast trip time of 0.15 seconds, ensuring quick protection. Terminal material is tin plated copper for excellent electrical connectivity and corrosion resistance.

The fuse operates reliably from -40°C to 85°C, supporting diverse industrial and commercial applications. Rated for power dissipation of 0.8W, the fuse maintains performance while minimizing heat generation. Certified RoHS compliant, it meets environmental safety standards.

This resettable fuse is maintenance free and designed for thousands of automatic reset cycles, reducing service costs and downtime. It is widely used in security systems, power supplies, automotive circuits, medical devices, instrumentation, telecommunications, and audio-visual equipment.
