MPTS2920L100

Ptc Resettable Fuses Overview

The MPTS2920L100 is a polymeric positive temperature coefficient (PTC) resettable fuse manufactured by Meritek Electronics Corporation. Designed in the 2920 surface-mount package, this component functions as a self-recovery overcurrent protector for electronic circuits. It features a maximum operating voltage of 33V and a hold current of 1.1A at 23°C in still air. The device automatically increases resistance to limit current flow during fault conditions, resetting once the fault is removed and the unit cools down.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC construction for reliable overcurrent protection
• Self-resetting capability after fault condition removal
• Surface-mount 2920 package design for automated assembly

Ptc Resettable Fuses Applications

• Portable electronics circuit protection
• Consumer appliance power lines
• Industrial control board overcurrent safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet revision when sourcing to ensure alignment with current manufacturing standards. Confirm that the 2920 package dimensions match your PCB footprint requirements. Check for any updated thermal derating curves if operation in environments exceeding standard ambient temperatures is planned. Ensure suppliers provide genuine Meritek components to guarantee electrical performance consistency.

Ptc Resettable Fuses Selection Notes

Select this component based on the 1.1A hold current requirement and 33V system voltage. Evaluate the trip time characteristics against the protected circuit's tolerance for transient currents. Consider the physical space constraints of the 2920 package within the final assembly. Verify that the thermal environment supports the necessary cooling for effective reset cycles after tripping events occur.

Ptc Resettable Fuses Part Context

This part belongs to Meritek’s line of polymeric PTC resettable fuses, which are passive circuit protection devices. These components serve as alternatives to traditional one-time fuses by offering reusable protection. The series is engineered for applications requiring compact footprints and reliable recovery from overcurrent faults without manual replacement.

Ptc Resettable Fuses Replacement Considerations

Consult official Meritek documentation for direct cross-reference equivalents. Verify that any substitute maintains identical voltage ratings, hold current specifications, and package dimensions to ensure compatibility.
