Overview
The MINISMDC260F/13.2-2 is a polymeric PTC resettable fuse from the Littelfuse miniSMD series, designed for surface-mount applications in the 1812 (4532 Metric) concave package. It features a maximum voltage rating of 13.2V and a hold current (Ih) of 2.6A. The device trips at 5A with a typical trip time of 5 seconds. Initial resistance (Ri) is minimum 15 mOhms, while post-trip resistance (R1) is maximum 50 mOhms. It supports a maximum fault current of 100A and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Polymeric construction enables self-resetting functionality after fault conditions clear.
- Surface-mount 1812 concave package facilitates automated assembly and compact PCB integration.
- Certified by CSA, TUV, and UL agencies for global compliance requirements.
Applications
- Overcurrent protection for portable electronic devices
- Circuit protection in automotive electronics
- Industrial control unit safeguarding
Procurement Notes
Verify the specific voltage suffix (13.2V vs 16V) against circuit design requirements, as variants like MINISMDC260F/16-2 share identical current ratings but differ in voltage limits. Confirm package orientation and soldering profile compatibility with the 1812 concave form factor. Ensure supply chain sources provide original Littelfuse documentation to validate authenticity and traceability.
Selection Notes
Select this component when a low-profile surface-mount solution is required for circuits operating up to 13.2V. The 2.6A hold current suits moderate power loads, while the 5A trip threshold provides immediate fault response. Consider the 15 mOhm initial resistance for minimal voltage drop impact. Evaluate thermal derating needs if ambient temperatures approach the 85°C upper limit.
Part Context
This part belongs to the PolySwitch miniSMD family, which offers compact circuit protection solutions. It complements other SMD fuses like the SMD260F-2, though that variant differs in voltage rating (6V) and package size (2-SMD). The miniSMD series emphasizes small footprint and high reliability for modern electronics manufacturing.
Replacement Considerations
MINISMDC260F/16-2 serves as a direct substitute if the application voltage exceeds 13.2V but remains within 16V, maintaining identical 2.6A hold and 5A trip characteristics.
