MICROASMDCH110F-2

Overview

The MICROASMDCH110F-2 is a PolySwitch resettable fuse from the microASMDCH series, manufactured by Littelfuse. It is designed for surface-mount technology (SMD/SMT) applications with a 1210 (3225 metric) package footprint. The device features a holding current of 1.1 A and a trip current of 2.2 A. It supports a maximum voltage of 16 VDC and has a maximum rated current of 40 A. The initial resistance is 1 Ohm, with a power dissipation of 1 W. Operating temperatures range from -40 C to +125 C.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon fault clearance.
Engineered for high-temperature automotive environments with robust thermal stability.
Utilizes polymer positive temperature coefficient (PPTC) technology for reliable circuit safeguarding.

Applications

Automotive electronics requiring AEC-Q200 compliance
High-temperature surface-mount circuit protection
Consumer electronics with compact form factor requirements

Procurement Notes

Verify component authenticity using official Littelfuse documentation and part number identifiers. Confirm that the received items match the specified 1210 package dimensions and electrical ratings. Check for moisture sensitivity labeling as indicated in technical specifications. Ensure storage conditions comply with humidity requirements to maintain device integrity prior to assembly.

Selection Notes

Select this component when a 1.1 A holding current and 16 VDC rating are required for space-constrained designs. The 1210 package offers a balance between current capacity and board area efficiency. Consider the 125 C maximum operating temperature for applications involving significant self-heating or elevated ambient conditions. Verify compatibility with reflow soldering profiles suitable for PPTC devices.

Part Context

This part belongs to the microASMDCH series, which represents high-temperature polymeric resettable fuses. It shares design characteristics with other Littelfuse SMD fuses but is distinguished by its specific current and voltage ratings. The series is tailored for automotive and industrial applications where reliability under thermal stress is critical.

Replacement Considerations

Official substitutes include RF5034-000 and MICROASMDCH075F-2. Cross-reference electrical parameters such as holding current, trip current, and voltage ratings before substitution. Verify package compatibility and thermal performance to ensure equivalent circuit protection capabilities.
