R2920-100-60-R

Ptc Resettable Fuses Overview

The OptiFuse R2920-100-60-R is a surface-mount polymeric resettable fuse (PTC) from the R2920-R series. It features a maximum voltage rating of 60V and a hold current (Ih) of 1.1A. The device has a maximum trip current of 2.2A and a maximum interrupting current (Imax) of 100A. Its minimum resistance is 90mΩ, with a power rating of 1.5W. The component utilizes a 2920 package footprint, measuring approximately 5.1mm by 7.4mm, designed for automated SMD assembly.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC technology provides automatic reset capability after fault clearance
• Surface-mount design compatible with standard reflow soldering processes
• High interrupting capacity ensures safety during severe overcurrent events

Ptc Resettable Fuses Applications

• Portable electronic devices requiring circuit protection
• Consumer electronics power input lines
• Data interface circuits susceptible to transient overcurrent

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm that the 60V rating aligns with the system's maximum operating voltage under all conditions. Ensure the 1.1A hold current meets the continuous load requirements without nuisance tripping. Check compatibility with the manufacturing facility's peak reflow temperature profiles.

Ptc Resettable Fuses Selection Notes

Select this component when a 60V maximum voltage and 1.1A continuous current are required in a compact SMD form factor. The 2920 case size offers a balance between current handling and board space. Consider the 90mΩ minimum resistance impact on low-voltage drop applications. Evaluate the 100A Imax rating against potential short-circuit scenarios in the target circuit design.

Ptc Resettable Fuses Part Context

This part belongs to the OptiFuse R2920-R series of resettable fuses. The series provides various hold current options within the same 2920 physical footprint. These components serve as reusable alternatives to traditional one-time fuses in modern electronics manufacturing.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other R2920-R series variants with different hold currents, such as R2920-075-60-R for lower current needs. Cross-brand replacements require matching the 2920 package dimensions, 60V rating, and 1.1A hold current specifications.
