MINISMDC260F/12-2

Overview

The Littelfuse MINISMDC260F/12-2 is a PolySwitch resettable PPTC device designed for surface-mount applications. It features a 1.25 A hold current and an 8 VDC maximum voltage rating, with a trip current of 2.5 A. The component offers a maximum interrupting rating of 100 A and exhibits a typical resistance of 140 mOhms. Housed in a compact 1812 (4532 metric) package, it operates within a temperature range of -40°C to +85°C. This device provides reliable overcurrent protection for sensitive electronic circuits while maintaining low profile dimensions suitable for modern PCB layouts.

Feature Summary

Provides automatic circuit recovery after fault conditions without manual replacement
Utilizes polymer positive temperature coefficient technology for rapid response to overcurrent events
Designed for surface-mount integration on printed circuit boards

Applications

Portable consumer electronics protection
Battery pack circuit safeguarding
Data line surge and overcurrent protection

Procurement Notes

Verify the specific voltage and current ratings against the target circuit requirements before procurement. Confirm that the 1812 package dimensions align with the designated footprint on the printed circuit board. Ensure compliance with RoHS directives and moisture sensitivity level classifications relevant to the assembly process. Cross-reference the manufacturer datasheet for precise thermal derating curves and time-current characteristics to validate performance under expected operating loads.

Selection Notes

Select this component when a low-profile, surface-mount resettable fuse is required for circuits operating at voltages up to 8 VDC. The 1.25 A hold current makes it suitable for protecting low-power data lines or battery cells. Consider the 100 A interrupting rating to ensure safety during short-circuit scenarios. Evaluate the thermal environment to ensure the device can dissipate heat effectively within the specified operating temperature range without nuisance tripping.

Part Context

This part belongs to the miniSMD series of PolySwitch resettable fuses from Littelfuse. The series is characterized by its small form factor and reliability in consumer and industrial applications. It serves as a reusable alternative to traditional one-time fuses, offering cost savings and design flexibility. The miniSMD line is widely recognized for its consistent performance in protecting sensitive semiconductor components from damage due to overcurrent conditions.
