Overview
The Littelfuse MINISMDC010F-2 is a surface-mount polymer positive temperature coefficient (PPTC) resettable fuse from the miniSMDC series. It features a hold current of 100 mA and a trip current of 300 mA, with a maximum voltage rating of 60 VDC. The device has a typical resistance of 12.7 Ohms and a maximum fault current rating of 40 A. It operates within a temperature range of -40°C to +85°C and is housed in an 1812 package measuring 4.73 mm in length, 3.41 mm in width, and 0.89 mm in height.
Feature Summary
- Provides overcurrent protection through automatic circuit interruption upon excessive heat generation.
- Offers repeated protection capability by resetting automatically after the fault condition is removed and the device cools down.
- Designed for surface mount technology integration into compact electronic assemblies.
Applications
- Automotive electronics circuits requiring AEC-Q200 qualification
- Portable consumer electronic devices needing compact circuit protection
- Industrial control systems utilizing surface mount components
Procurement Notes
Verify component authenticity against official Littelfuse documentation before integration. Confirm that the specific part number matches project requirements for electrical ratings and physical dimensions. Ensure compliance with RoHS directives and moisture sensitivity levels as specified in the manufacturer datasheet. Validate supplier authorization to prevent counterfeit risks.
Selection Notes
Select this component when a 100 mA hold current and 60 VDC rating are required for space-constrained applications. The 1812 package size offers a balance between current handling capacity and board real estate. Consider the 12.7 Ohm resistance impact on circuit efficiency during normal operation. Evaluate thermal management needs given the 85°C maximum operating temperature limit.
Part Context
This device belongs to the miniSMDC family of PolySwitch resettable fuses designed for automotive and industrial markets. It complements other Littelfuse SMD protection solutions by offering higher voltage tolerance compared to lower-voltage series. The product line emphasizes reliability and compact form factors for modern PCB designs.
Replacement Considerations
MINIASMDC010F-2 serves as a direct replacement option within the same manufacturer portfolio, sharing similar electrical characteristics but differing in package dimensions. Cross-reference datasheets to ensure mechanical fit and thermal performance compatibility before substitution.
