The Littelfuse 0251004.NRT1L is a very fast-acting fuse from the PICO II series (251 Series). It is designed for secondary overcurrent protection in space-constrained electronic applications. With a subminiature axial lead package, this fuse provides reliable circuit protection in a small footprint.
This fuse is rated for 4A of current at 125V AC/DC. Its fast blow response time ensures rapid opening under overcurrent conditions. Electrical specifications include a breaking capacity of 50A AC and 300A DC at rated voltage, a melting I²t of 2.45 A²s, a cold resistance of 0.0204 ohms, and a low voltage drop of 0.114V. The operating temperature range spans -55°C to 125°C.
The 0251004.NRT1L fuse mounts through a through-hole axial lead configuration, with package dimensions of 0.110 inches diameter by 0.280 inches length (2.80mm x 7.11mm). It is suitable for automated insertion or manual assembly.
This component carries safety approvals from CCC, CSA, cURus, PSE, and TUV, ensuring compliance with international standards. It is commonly used in power supplies, flat-panel displays, lighting systems, and medical equipment.
