MICROSMDCH010F-02

Overview

The Littelfuse MICROSMDCH010F-02 is a surface-mount polymeric PTC resettable fuse from the microSMD series. It features a hold current of 100 mA and a trip current of 300 mA, rated for a maximum voltage of 30 VDC. The device offers a high fault current rating of 10 A and maintains a typical resistance of 7 Ohms. Housed in a compact 1210 (3225 Metric) package with dimensions of 3.2 mm x 2.5 mm x 0.89 mm, it operates within a temperature range of -40°C to +125°C and dissipates up to 900 mW.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after fault clearance.
Designed for surface mount assembly using standard SMD/SMT placement processes.
Constructed as a polymer positive temperature coefficient device for reliable circuit interruption.

Applications

Portable electronic device circuit protection
Automotive electronics safeguarding
Industrial control system input/output lines

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm moisture sensitivity handling requirements are met during storage and reflow soldering. Ensure the specific suffix matches the required electrical characteristics for the target application design.

Selection Notes

Select this component when space-constrained designs require a 1210 footprint for resettable fusing. Consider the 30VDC rating and 100mA hold current for low-voltage signal or power line protection. Evaluate thermal management needs given the 900mW power dissipation capability in enclosed environments.

Part Context

This part belongs to the microSMD family of PolySwitch resettable fuses, which are engineered for high-reliability applications requiring compact protection solutions. The series supports various hold currents and voltage ratings across different package sizes to accommodate diverse circuit protection needs in modern electronics manufacturing.

Replacement Considerations

Direct substitutes include MICROSMD010F-2 and MICROSMDCH010F-2, provided they meet identical voltage, current, and package constraints. Verify that alternative parts maintain the same 1210 footprint and thermal performance characteristics.
