MINISMDC150F-2

Overview

The Littelfuse MINISMDC150F-2 is a PolySwitch resettable PPTC fuse designed for surface mount applications. It features a 6V DC maximum voltage rating and a 1.5A hold current, with a trip current of 3A. The device supports a maximum fault current of 100A and operates within a temperature range of -40°C to +85°C. Housed in an 1812 (4532 metric) package measuring 4.73mm x 3.41mm x 0.48mm, it exhibits a maximum resistance of 110mΩ and a power dissipation of 0.8W.

Feature Summary

Provides automatic circuit protection through polymer positive temperature coefficient technology
Enables rapid response to overcurrent conditions without permanent damage
Supports reflow soldering processes for automated surface mount assembly

Applications

Overcurrent protection for portable electronic devices
Protection circuits in battery-powered equipment
Surge protection for telecommunications interfaces

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Littelfuse documentation. Confirm that the physical package dimensions match the specified 1812 footprint and that terminal materials are consistent with tin-plated specifications. Ensure operational parameters align with the required system voltage and current thresholds before integration.

Selection Notes

Select this component when space-constrained designs require a resettable protection mechanism for low-voltage circuits. The 1812 package offers a balance between current handling capacity and board real estate. Consider the 100A maximum interrupting rating to ensure safety during high-fault scenarios while maintaining compatibility with standard SMT manufacturing processes.

Part Context

This device belongs to the MINISMDC series, which provides compact resettable fuses for modern electronics. The series utilizes proprietary polymer technology to deliver reliable protection in small form factors. It serves as a robust alternative to traditional fusible links in applications requiring repeated overload recovery.
