MINISMDC075-2

Overview

The Littelfuse MINISMDC075-2 is a PolySwitch resettable PPTC fuse in the miniSMD series, housed in an SMD/SMT 1812 (4532 metric) package. It features a hold current of 750 mA and a trip current of 1.5 A with a maximum voltage rating of 13.2 VDC. The device has a maximum resistance of 450 mOhms and a rated power dissipation of 1 W. It operates within a temperature range of -40°C to +85°C and supports a maximum fault current of 100 A.

Feature Summary

Provides automatic circuit protection by increasing resistance during overcurrent or overheating events
Offers manual reset capability after the fault condition is removed and the device cools down
Designed for surface mount integration into compact electronic assemblies

Applications

Portable electronics and mobile devices
Laptop computers and peripheral equipment
Automotive electronics systems

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical ratings. Ensure the selected variant matches the required voltage and current specifications for the target application. Confirm compliance with RoHS standards and moisture sensitivity levels before procurement.

Selection Notes

Select this component based on the 1812 footprint constraint and the 750 mA hold current requirement. Evaluate the 13.2 VDC maximum voltage rating against the circuit's operating conditions. Consider the thermal environment to ensure operation remains within the specified -40°C to +85°C range.

Part Context

This part belongs to the Littelfuse PolySwitch miniSMD family of resettable fuses. These components are engineered for high-reliability applications requiring compact overcurrent protection solutions that do not require replacement after tripping.
