Ptc Resettable Fuses Procurement Notes

Verify the specific suffix (e.g., -R) indicates tape and reel packaging if required for automated assembly. Confirm the datasheet version matches the production batch for accurate electrical characteristics. Ensure the supplier provides genuine OptiFuse products to guarantee performance reliability and compliance with specified ratings.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable solution is preferred over disposable fuses for maintenance efficiency. Consider the 60V maximum voltage limit and 100A interrupting capacity for system compatibility. Evaluate the thermal environment to ensure the hold current remains effective under operating temperatures. Compare initial resistance values against other series options for signal integrity requirements.

Ptc Resettable Fuses Part Context

This part belongs to the R1206 Series of PTC resettable fuses from OptiFuse. The series offers various current ratings ranging from 50mA to 2A within the same 1206 footprint. This specific model represents the lower current end of the spectrum, suitable for sensitive low-power circuits. The series is designed for high-volume manufacturing and reliable long-term performance.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 1206 PTC fuses with matching 60V and 100mA ratings. Verify that alternative brands maintain similar trip times and resistance profiles. Ensure the replacement component supports the same PCB footprint and reflow soldering requirements. Check for any differences in maximum fault current handling capabilities.
