1210L300SLWR Description

Short technical summary and product information.

The Littelfuse 1210L300SLWR is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in electronic circuits. It is rated for a maximum voltage of 6V and a hold current of 3A, making it suitable for low-voltage applications.

 

With a low initial resistance of 20 mΩ, the device minimizes power loss and heat generation during normal operation. The trip time is 2 seconds, providing rapid response to overcurrent conditions. The fuse is surface mountable with a 1210 (3225 Metric) concave package, measuring 3.22mm by 2.58mm with a maximum thickness of 0.70mm.

 

This component can operate over a temperature range of -40°C to 85°C, accommodating a wide variety of environments. The polymeric construction ensures automatic reset after the fault is cleared, reducing maintenance and replacement costs. Typical applications include overcurrent protection in consumer electronics, battery circuits, and portable devices.
