The Littelfuse 0459.750UR is a 459 series PICO SMF very fast-acting surface mount fuse designed for overcurrent protection in compact electronic assemblies. It is rated for 750mA at 125VAC and 125VDC, with a breaking capacity of 50A AC and 300A DC. The fuse exhibits a fast blow response time, opening within 1 second at 200% of rated current and within 0.1 second at 300%.
This fuse is housed in a 2-SMD, J-Lead package measuring 7.24mm x 4.32mm x 3.05mm, making it suitable for high-density board layouts. The body is molded thermoplastic with tin-plated copper terminations, and it meets MIL-STD-202 solderability requirements. The nominal cold resistance is 0.1750 ohms, and the melting I²t is 0.155 A²sec.
Intended applications include wireless basestations, network equipment, and telecom equipment where reliable overcurrent protection is needed. The fuse operates over a temperature range of -55°C to 125°C and is rated MSL 1 (unlimited) per J-STD-020. It is RoHS compliant and carries CSA and UL agency approvals.
The current rating is 750 mA.
The voltage rating is 125 VAC and 125 VDC.
The breaking capacity is 50 A AC and 300 A DC at rated voltage.
It is a very fast-acting (fast blow) fuse. Opening time: 1 second max at 200% rated current, 0.1 second max at 300%.
It comes in a 2-SMD, J-Lead surface mount package measuring 7.24mm x 4.32mm x 3.05mm.
The operating temperature range is -55°C to 125°C.
Yes, it is RoHS3 compliant as verified from the datasheet.
