The Littelfuse 37200400001 is a 40mA, 250V time-lag (slow blow) fuse designed for board mount applications. It features a through hole mounting type with a radial can vertical package measuring 8.50mm diameter by 8.00mm height. The fuse has a breaking capacity of 35A at rated voltage and a cold resistance of 10.165 ohms. Its maximum voltage drop at 1.0×IN is 900mV, and maximum power dissipation at 1.5×IN is 90mW. The operating temperature range is -40°C to 85°C.
This fuse is part of the Littelfuse 372 Series TR5 family, designed in accordance with IEC 60127-3. It is halogen free, lead-free, and RoHS compliant. The slow blow characteristic allows it to withstand temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive or inductive loads. The fuse is approved by cURus and VDE agencies.
