The Littelfuse 0449002.MR is a 2A board mount fuse designed for overcurrent protection in surface mount applications. It is rated for 125VAC and 125VDC with a breaking capacity of 50A at rated voltage. The slow blow (time-delay) characteristic allows the fuse to tolerate temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive or inductive loads.
This fuse is housed in a compact 2-SMD square end block package measuring 6.10mm x 2.69mm x 2.69mm. It operates over a wide temperature range of -55°C to 125°C. The melting I²t value is 6.76, providing predictable performance under fault conditions.
Approvals include cULus and PSE, indicating compliance with North American and Japanese safety standards. The surface mount design enables automated assembly, reducing manufacturing costs.
The current rating is 2 A.
The voltage rating is 125 V for both AC and DC.
The breaking capacity is 50 A at rated voltage.
The response time is slow blow (time-delay).
It comes in a 2-SMD, square end block package.
The operating temperature range is -55°C to 125°C.
It is approved by cULus and PSE.
