MICROSMD010F-02

Overview

The Littelfuse MICROSMD010F-02 is a PolySwitch resettable fuse from the microSMD series, designed for surface-mount applications. It features a 30 VDC maximum voltage rating and a 0.1 A hold current. The device trips at 0.25 A and withstands a maximum fault current of 10 A. Its initial resistance is 50 Ohms, with a power dissipation of 800 mW. The component operates within a temperature range of -40°C to +85°C and is housed in a 1210 (3225 metric) package.

Feature Summary

Provides automatic circuit protection through self-resetting PPTC technology
Designed for compact surface-mount PCB integration
Complies with automotive reliability standards

Applications

Automotive electronics circuits
Portable electronic device protection
Consumer appliance overcurrent safeguarding

Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm exact electrical characteristics and packaging configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet prior to procurement.

Selection Notes

Select this component when low current protection is required for space-constrained designs. Evaluate the high initial resistance value against signal integrity requirements. Confirm that the 30 VDC rating aligns with the system's operating voltage and transient conditions.

Part Context

This part belongs to the microSMD family of resettable fuses, offering a balance between current handling capacity and physical footprint. It utilizes PolySwitch technology to provide reusable overcurrent protection without requiring manual replacement after a fault event.
