2920L200DR Description

Short technical summary and product information.

The Littelfuse 2920L200DR is a polymeric PTC resettable fuse from the 2920L Series, designed for overcurrent protection in medium voltage applications up to 15V. It features a hold current of 2 A at 20°C still air and a minimum trip current of 4 A. The device can withstand a maximum fault current of 40 A and has a typical power dissipation of 1.5 W when tripped.

 

This resettable fuse offers a maximum time to trip of 5 seconds at 8 A, with an initial minimum resistance of 0.05 Ω and a maximum resistance of 0.125 Ω one hour after tripping or reflow soldering. It is suitable for applications requiring resettable overcurrent protection in compact designs.

 

The component is housed in a 2920 (7351 Metric) concave surface mount package with dimensions of 7.35 mm length, 5.12 mm width, and a maximum thickness of 1.25 mm. It operates over a temperature range of -40°C to 85°C.
