The 1812L125/16DR is a PolySwitch polymeric PTC resettable fuse from Littelfuse, designed for surface mount overcurrent protection. It offers a hold current of 1.25A and a trip current of 2.5A, with a maximum voltage rating of 16V DC. The device features a fast trip time of 400 ms and low resistance values: initial resistance of 0.05Ω and trip resistance of 0.14Ω.
This fuse is packaged in a compact 1812 (4532 Metric) concave surface mount package, measuring 4.55mm x 3.24mm x 1.25mm. It operates over a temperature range of -40°C to 85°C and is compatible with high temperature soldering processes. The part is RoHS compliant, lead-free, and halogen-free as per the datasheet.
Typical applications include plug and play protection for motherboards and peripherals, USB peripherals, PCI cards, and game console port protection. The 1812L125/16DR is also suitable for general overcurrent protection in low-voltage DC circuits where resettable protection is required.
