MINISMDC010-02

Overview

The Littelfuse MINISMDC010-02 is a PolySwitch resettable PPTC fuse in the miniSMDC series, housed in an 1812 surface-mount package. It features a 60 VDC maximum voltage rating and a 40 A maximum fault current capacity. The device maintains a hold current of 100 mA and trips at 300 mA. Initial resistance is typically 12.7 Ohms, with a power dissipation of 750 mW. Operating temperatures range from -40°C to +85°C.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after a trip event
Designed for surface mounting on printed circuit boards using standard SMD/SMT processes
Constructed with a polymer positive temperature coefficient material for reliable circuit interruption

Applications

Portable electronic devices requiring compact circuit protection
Battery-powered equipment needing overcurrent safeguarding
Data line protection in communication interfaces

Procurement Notes

Verify the specific suffix designation during procurement, as variations such as MINISMDC010F-2 may indicate different packaging or certification statuses. Confirm that the selected part number matches the required electrical parameters and physical dimensions for your design. Ensure compatibility with your manufacturing process regarding moisture sensitivity levels and reflow soldering profiles before finalizing orders.

Selection Notes

Select this component when space constraints require an 1812 footprint for resettable protection. Evaluate the 12.7 Ohm initial resistance to ensure it does not adversely affect signal integrity or power delivery in low-voltage applications. Consider the 750 mW power dissipation rating relative to ambient thermal conditions to prevent premature tripping during normal operation.

Part Context

This part belongs to Littelfuse's miniSMDC family of resettable fuses, which are engineered for high-reliability circuit protection in small form factors. The series utilizes proprietary polymer technology to provide robust overcurrent defense without permanent damage to the component after fault clearance.
