Overview
The Littelfuse MICROSMD005F-2 is a PolySwitch resettable PPTC device in the microSMD series. It features a 30 VDC maximum voltage rating and a 50 mA hold current. The trip current is specified at 150 mA, with a maximum interrupt rating of 10 A. The component utilizes a 1210 (3225 metric) surface mount package. It operates within a temperature range of -40°C to +85°C and holds AEC-Q200 qualification for automotive applications.
Feature Summary
- Provides automatic circuit protection through polymer positive temperature coefficient technology
- Designed for surface mount integration into compact electronic assemblies
- Certified to AEC-Q200 standards for automotive reliability requirements
Applications
- Automotive electronics circuits requiring AEC-Q200 compliance
- Overcurrent protection for low-voltage DC power lines
- Portable consumer device battery protection
Procurement Notes
Verify the specific datasheet revision and manufacturer documentation before finalizing design-in decisions. Confirm that the 1210 package dimensions align with the target PCB footprint. Ensure the application environment remains within the specified -40°C to +85°C operating range to maintain rated performance characteristics.
Selection Notes
Select this component when a 50 mA hold current and 30 VDC rating are required for space-constrained designs. The 1210 package offers a balance between current handling capability and board area efficiency compared to smaller form factors. Consider the AEC-Q200 qualification if the end product targets automotive market segments.
Part Context
This part belongs to the microSMD series of resettable fuses from Littelfuse. The series focuses on providing reliable overcurrent protection in small surface-mount packages suitable for modern high-density PCB layouts. The microSMD line is engineered to replace traditional fusible resistors in various commercial and industrial applications.
Replacement Considerations
Cross-reference with other Littelfuse microSMD variants such as MICROSMD010F-2 or MICROSMD020F-2 if different current ratings are needed while maintaining the same package and voltage specifications.
