2920L400/15MR Description

Short technical summary and product information.

The Littelfuse 2920L400/15MR is a PolySwitch resettable PTC overcurrent protection device designed for surface mount applications. It offers a hold current of 4.00 A at 20°C still air and a trip current of 8.00 A, with a maximum voltage rating of 15 V and a maximum fault current of 40 A. The device trips within 4.00 seconds at 20 A.

 

This polymeric PTC fuse features a low initial resistance of 0.010 Ω and a maximum post-trip resistance of 0.040 Ω, minimizing power loss during normal operation. Typical power dissipation in the tripped state is 1.50 W. It operates over a temperature range of -40°C to 85°C.

 

The component is housed in a 2920 (7351 Metric) concave surface mount package measuring 7.36 mm x 5.12 mm with a maximum thickness of 1.60 mm. It is suitable for automated assembly and reflow soldering processes.
