37012000000 Description

Short technical summary and product information.

The Littelfuse 37012000000 is a board mount fuse from the 370 Series, part of the TR5 family. It is a fast-acting (fast blow) fuse rated for 2A at 250VAC. This through-hole radial can vertical fuse provides a 50A breaking capacity at the rated voltage, meeting requirements for a variety of circuit protection applications.

 

Electrical characteristics include a nominal cold resistance of 0.0325 ohms, a maximum voltage drop of 85 mV at 1.0×IN, and a maximum power dissipation of 500 mW at 1.5×IN. The melting integral at 10×IN is 0.98 A²s. The fuse operates over a temperature range of -40°C to 85°C.

 

The radial lead package measures 0.335" diameter by 0.315" height (8.50mm x 8.00mm), designed for compact PCB layouts. It is approved by CCC, cURus, PSE, SEMKO, and VDE. The datasheet indicates the fuse is lead-free, halogen free, and RoHS compliant.

 

Typical applications include battery chargers, consumer electronics, power supplies, and industrial controllers. The 370 Series offers low internal resistance, a shock-safe casing, and vibration resistance.
