37201000001 Description

Short technical summary and product information.

The Littelfuse 37201000001 is a 372 Series TR5 time lag (slow blow) fuse designed for board mount applications. It is rated at 100mA and 250VAC with a breaking capacity of 35A. This fuse provides reliable overcurrent protection with a characteristic slow response to inrush currents.

 

Electrical characteristics include a nominal cold resistance of 1.703 ohms, a voltage drop of 300 mV maximum at rated current, and power dissipation of 110 mW maximum at 1.5x rated current. The melting I²t value is 0.08 A²s. Opening times are specified for multiple overcurrent levels: 1 hour minimum at 150%, 2 minutes maximum at 210%, 400 ms to 10 s at 275%, 150 ms to 3 s at 400%, and 20 ms to 150 ms at 1000%.

 

The fuse is packaged in a radial can vertical through-hole format with dimensions 8.50mm x 8.00mm and operates over -40°C to 85°C. Safety approvals include CCC, cURus, SEMKO, and VDE. Typical applications include battery chargers, consumer electronics, power supplies, and industrial controllers.
