MINISMDC014F-2

Overview

The Littelfuse MINISMDC014F-2 is a PolySwitch resettable PPTC fuse in the miniSMD series. It features a 60 VDC maximum voltage rating and a 140 mA hold current. The trip current is specified at 280 mA, with a maximum resistance of 6 Ohms. It supports a maximum fault current of 10 A and dissipates up to 750 mW. Operating within a -40°C to +85°C range, it utilizes SMD/SMT termination on a 1812 (4532 metric) package.

Feature Summary

Provides automatic circuit protection through positive temperature coefficient polymer technology
Enables reusable safety by resetting automatically after fault conditions clear
Designed for surface mount integration using standard SMD/SMT assembly processes

Applications

Portable electronic device power line protection
Consumer electronics overcurrent safeguarding
Communication equipment circuit defense

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number MINISMDC014F-2 against official Littelfuse documentation. Confirm that the datasheet specifications match the required electrical parameters for your specific application design. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to soldering to maintain reliability.

Selection Notes

Select this component when a 60 VDC rating and 140 mA hold current are required for compact circuit protection. The 1812 package size suits space-constrained designs needing surface mount compatibility. Evaluate the 6 Ohm resistance and 750 mW power dissipation limits to ensure thermal management aligns with system constraints during normal operation.

Part Context

This device belongs to the miniSMD family of PolySwitch resettable fuses from Littelfuse. These components utilize conductive polymer technology to offer reliable overcurrent protection in a small form factor. The series is engineered for high-volume manufacturing environments requiring consistent performance across diverse consumer and industrial applications.
