The Littelfuse MICROSMD250LR-A-2 is a polymeric PTC (Positive Temperature Coefficient) resettable fuse designed for overcurrent protection in electronic circuits. It has a hold current rating of 2.5 A and a maximum voltage rating of 6 V DC. The device features a low on-resistance of 5 mΩ, minimizing power loss during normal operation, and a typical time-to-trip of 5 seconds at fault conditions.
This resettable fuse is housed in a compact 1210 (3225 Metric) concave surface mount package, measuring 3.22 mm in length, 2.58 mm in width, and 1.00 mm in maximum thickness. The surface mount design enables automated assembly and is suitable for space-constrained PCB layouts.
Polymeric PTC fuses are commonly used in applications requiring resettable overcurrent protection, such as USB ports, battery packs, and peripheral interfaces. The MICROSMD250LR-A-2 provides a reliable, self-resetting alternative to traditional one-time fuses.
