0251003.NRT1L Description

Short technical summary and product information.

The Littelfuse 0251003.NRT1L is a board mount fuse from the PICO II 251 series, designed for very fast-acting overcurrent protection in space-constrained applications. It is rated for a current of 3 A and a voltage of 125 V (AC/DC), with a breaking capacity of 50 A AC and 300 A DC. Its fast blow response time ensures rapid disconnection during overcurrent events, making it suitable for protecting sensitive circuits. The fuse is housed in an axial through-hole package with dimensions of 0.110" diameter by 0.280" length (2.80mm x 7.11mm) and is designed for soldered mounting on printed circuit boards. It is RoHS3 compliant and has agency approvals including CCC, CSA, cURus, PSE, and TUV. This component is commonly used in power supplies, LCD displays, and other electronic equipment requiring secondary protection in a compact form factor.
