SMD100F-2 Description

Short technical summary and product information.

The SMD100F-2 is a polymeric PTC resettable fuse from Littelfuse's PolySwitch family, designed for overcurrent protection in a compact surface mount package. It provides a hold current of 1.1A at a maximum voltage of 30V, with a low initial resistance of 480mΩ to minimize power loss during normal operation. The device trips within 500ms under fault conditions, offering fast protection.

 

This component is housed in a 2-SMD package with dimensions of 7.36mm length, 5.12mm width, and 3.00mm thickness, making it suitable for space-constrained designs. It operates over a temperature range of -40°C to 85°C and is RoHS compliant and halogen free. Typical applications include overcurrent protection in computer, portable electronics, multimedia, and automotive circuits.
