The Littelfuse 0459001.UR is a 1A, 125V very fast-acting surface mount fuse from the 459 Series PICO® SMF family. It is designed for overcurrent protection in space-constrained applications demanding reliable circuit interruption.
This fuse offers a breaking capacity of 50A at 125VAC and 300A at 125VDC, with a nominal cold resistance of 0.1280 Ω and a melting I²t of 0.281 A²sec. It is rated for fast response, opening within 1 second at 200% of rated current and within 0.1 second at 300%.
The device is housed in a 2-SMD, J-Lead package measuring 7.24mm x 4.32mm x 3.05mm, suitable for automated surface mount assembly. It operates over a temperature range of -55°C to 125°C and is RoHS compliant with MSL 1 (unlimited).
Applications include wireless basestations, network equipment, and telecom equipment where fast-acting overcurrent protection is required. The fuse is approved by CSA and UL (file E10480 for 0.062-5A).
The current rating is 1 A.
The voltage rating is 125 V AC and DC.
The breaking capacity is 50 A at 125 VAC and 300 A at 125 VDC.
It is a very fast-acting (fast blow) fuse, opening within 1 second at 200% of rated current and within 0.1 second at 300%.
It comes in a 2-SMD, J-Lead surface mount package.
The operating temperature range is -55°C to 125°C.
Yes, it is RoHS3 compliant as verified by the datasheet.
