MINISMDC150-2

Overview

The Littelfuse MINISMDC150-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the miniSMD series. It provides overcurrent protection with a maximum voltage rating of 6 VDC and a trip current of 3 A. The device maintains a holding current of 1.5 A and withstands a maximum fault current of 100 A. Its resistance ranges from a minimum of 40 mΩ to a maximum of 110 mΩ, with a power dissipation of 800 mW. The component operates within a temperature range of -40°C to +85°C and features tin-plated terminals in an 1812 package.

Feature Summary

Utilizes polymer PTC technology for automatic circuit recovery after fault conditions
Provides dual protection against overcurrent events and short circuits
Designed for direct surface mounting on printed circuit boards

Applications

Protection of portable electronic devices
Overcurrent safeguarding in battery-powered equipment
Circuit protection for LED arrays
Defense of AC-DC and DC-DC power adapters
Short circuit protection in networking equipment

Procurement Notes

Verify the specific suffix designation when sourcing components, as variations such as MINISMDC150F-2 may exist within the same family. Confirm that the procurement specification aligns with the required 6VDC rating and 1.5A holding current parameters. Ensure compliance with moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this component based on its 6VDC maximum voltage rating and 1.5A holding current capabilities. Evaluate the 1812 package dimensions to ensure compatibility with the target PCB footprint. Consider the 100A maximum current rating for short-circuit robustness and verify that the operating temperature range meets the environmental demands of the intended application design.

Part Context

This part belongs to the Littelfuse miniSMD series of resettable fuses. These devices are engineered specifically for surface-mount applications where space efficiency is critical. The series utilizes proprietary polymer technology to deliver reliable circuit protection in compact form factors suitable for modern electronics manufacturing processes.
