Littelfuse 0.25 A Resettable Fuse, 240 V AC/DC PolySwitch LVR Series LVR025K-2

The Littelfuse LVR025K-2 is a resettable fuse designed to protect electrical and electronic circuits from excessive currents and overheating. Rated at 0.25 A hold current with a trip current of 560mA, it operates on AC and DC voltages up to 240 V, making it suitable for a wide range of line-voltage applications.

The device offers fast response times with an 18.5-second trip time, ensuring effective circuit protection to prevent damage from surges or faults. Its compact physical dimensions (9.6mm length, 18.8mm height, 3.8mm width) allow easy integration into densely packed electronic assemblies.

Power dissipation of 1.5W and radial lead orientation facilitate efficient thermal management and PCB mounting respectively. The fuse complies with major international safety and quality standards including TUV, CSA, RoHS, and UL, guaranteeing reliability in critical applications.

Constructed with PolySwitch™ PPTC technology, the LVR series enables automatic reset thousands of times without replacement, offering maintenance-free circuit protection. Typical use cases cover medical devices, motor controls, fans and blowers, fire alarm and security systems, test and measurement equipment, transformers, USB hubs, and computer peripherals.

This device provides a robust safety solution that quickly transitions from low resistance to high resistance upon overcurrent conditions and automatically resets when normal operation resumes, minimizing downtime.

The fuse automatically resets itself multiple times, eliminating replacement costs. Small form factor saves PCB space and removes need for fuse holders. Low resistance maintains circuit efficiency under normal conditions.

Ideal for protecting sensitive electronic instrumentation and control equipment. Compatible with various industrial, medical, commercial, and consumer electronics applications.

The Littelfuse LVR025K-2 is a dependable, cost-effective choice within the electrical protection category, highly suitable for industrial, laboratory, HVAC, manufacturing, and agricultural environments.
