2016L050MR Description

Short technical summary and product information.

The Littelfuse 2016L050MR is a PolySwitch PTC resettable fuse from the 2016L series, designed for overcurrent protection in low voltage applications up to 60 V. It features a hold current of 550 mA and a trip current of 1.10 A at 20°C still air. The device can withstand a maximum fault current of 20 A and dissipates 1.40 W typical power in the tripped state.

 

This resettable fuse offers a maximum time to trip of 5 seconds at 2.5 A. Initial resistance is 0.200 Ω minimum, and post-trip resistance is 1.000 Ω maximum. It operates over a temperature range of -40°C to 85°C.

 

The component is housed in a 2016 (5041 Metric) concave surface mount package with dimensions 5.08 mm x 4.07 mm and a maximum thickness of 2.00 mm. It is RoHS3 compliant and halogen-free, suitable for automated assembly processes.
