0242.250UR – LITTELFUSE

The 0242.250UR from Littelfuse is a surface-mount fuse designed for overcurrent protection in both AC and DC circuits. This cartridge-style fuse has a current rating of 250mA and a voltage rating of 250VAC and 250VDC. The fuse is constructed to interrupt fault currents up to its interrupting rating, protecting downstream components from damage. Its surface-mount configuration facilitates automated assembly processes, reducing manufacturing costs and improving board density. The 0242.250UR is commonly utilized in applications requiring a compact, reliable overcurrent protection solution, such as power supplies, battery chargers, and various electronic modules. The fuse’s performance characteristics, including its I2t value and time-current curves, are detailed in the manufacturer’s datasheet and are critical for proper circuit design and coordination.
