Overview
The MINISMDC260F-2 is a polymer PTC self-resetting fuse from the miniSMD series by Littelfuse Inc. It features a maximum holding current of 2.6 A and a trip current of 5 A, with a maximum voltage rating of 16 V. The device has a maximum fault current capacity of 100 A and an initial resistance minimum of 15 mOhms. Post-trip resistance is capped at 50 mOhms. It operates within a temperature range of -40°C to 85°C in a compact 1812 (4532 metric) surface-mount package.
Feature Summary
- Utilizes polymer technology for automatic circuit protection that resets after fault clearance.
- Provides overcurrent protection through rapid tripping action upon exceeding specified current thresholds.
- Designed for surface-mount assembly in space-constrained electronic applications.
Applications
- Portable electronics power line protection
- Automotive interior circuit safeguarding
- Industrial control unit input/output protection
Procurement Notes
Verify component authenticity against official Littelfuse documentation. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 2A) requirements prior to soldering. Ensure storage conditions maintain integrity before reflow processes. Cross-reference datasheet parameters with specific application electrical constraints to guarantee reliable operation under expected load conditions.
Selection Notes
Select this component when a 16 V system requires 2.6 A continuous current handling with a 5 A trip threshold. Consider the 1812 footprint for PCB layout compatibility. Evaluate thermal dissipation needs as the device dissipates up to 800 mW. Verify that the 100 A maximum fault current rating exceeds potential surge currents in the target circuit design.
Part Context
This part belongs to the PolySwitch miniSMD family, designed for high-density surface-mount applications. It serves as a resettable alternative to traditional fuses in low-voltage circuits. The series offers various current ratings within standardized package dimensions to simplify supply chain management across different product lines.
Replacement Considerations
MINISMDC260F/16-2 is a confirmed substitute part number within the same manufacturer portfolio offering identical electrical characteristics and form factor.
