Product Description

Littelfuse 1206L025YR resettable fuse is a compact surface mount device designed to provide reliable overcurrent protection for electronic circuits running on 16V DC with a hold current of 0.25A. This 1206L series fuse automatically trips within 0.08 seconds at a trip current of 0.5A to prevent damage from excess current.

The fuse features a small footprint with dimensions 3.5mm length, 1.8mm width, and 1mm height, making it perfect for high-density circuit board applications. Its tin plated copper terminals ensure excellent electrical conductivity and solderability on PCBs.

Designed for maintenance-free automatic reset, the fuse can endure thousands of trip cycles, returning to low resistance state once the fault clears and power is removed. This eliminates the need for fuse replacement, enhancing reliability and reducing downtime.

The device operates efficiently between -40°C and 85°C ambient temperatures, supporting a variety of environments. It dissipates up to 0.6W of power during operation and maintains resistance between 0.55Ω minimum and 2.3Ω maximum under rated conditions.

Certified RoHS compliant, the Littelfuse 1206L025YR fuse suits critical industrial and commercial applications including security systems, power supplies, transformers, automotive electronics, medical devices, instrumentation, control systems, computers, peripherals, audiovisual and telecommunications equipment.

Rapid response to overcurrent with a 0.08 second trip time. Maintenance-free operation with automatic reset capability. Compact 1206 package ideal for space-saving designs. Wide temperature tolerance ensuring environmental resilience.

RoHS compliant and environmentally safe. High current rating of 100A suitable for demanding circuits. Reliable tin plated copper terminal material for durability. Used broadly in industrial, automotive, and medical electronics.
