0460003.UR Description

Short technical summary and product information.

The Littelfuse 0460003.UR is part of the 460 Series PICO Slo-Blo surface mount fuse family. It is rated at 3 amperes and 125 volts AC/DC, with a breaking capacity of 50 amperes. The fuse features a slow blow response time, making it suitable for applications with high inrush currents. The nominal cold resistance is 0.0380 ohm, and the nominal melting I²t is 18.15 A²sec.

 

The fuse body is constructed of molded thermoplastic with 100% tin-plated copper terminations. It is housed in a 2-SMD J-Lead package measuring 7.24 mm by 4.32 mm by 3.05 mm. The operating temperature range is -55°C to 125°C. It is RoHS compliant, halogen free, and carries agency approvals from CSA, PSE, and UL.

 

This surface mount fuse is designed for board-level overcurrent protection in equipment such as wireless basestations, network equipment, and telecom infrastructure. Its high inrush current withstand capability makes it a good fit for circuits with capacitive or inductive loads. The fuse meets MIL-STD-202 environmental test requirements for solderability, shock, vibration, and thermal shock.
