Ptc Resettable Fuses Procurement Notes

Verify the specific hold current rating of 2.5A and voltage rating of 60V against system requirements. Confirm the radial lead package type matches the PCB footprint. Ensure the operating temperature range of -40°C aligns with the intended environment. Cross-reference the part number RS60SB-250 with official OptiFuse documentation to confirm authenticity and specifications before procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable overcurrent protection solution is required for 60V DC circuits. The 2.5A hold current rating determines the continuous operational limit. Consider the through-hole mounting style if surface-mount alternatives are unsuitable. Evaluate the resistance range (40mΩ to 140mΩ) for impact on circuit efficiency. Ensure the thermal characteristics support the application's duty cycle.

Ptc Resettable Fuses Part Context

The RS60SB series comprises various polymeric PTC resettable fuses with different current ratings. The RS60SB-250 specifically denotes the 2.5A variant within this family. Other models in the series include ratings such as 0.5A, 1.35A, and 3.0A, all sharing similar voltage and package characteristics. This series is manufactured by OptiFuse for general electronic circuit protection needs.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 60V rating, 2.5A hold current, and radial lead package. Verify that alternative PTC fuses from other manufacturers meet the same resistance and thermal specifications. Ensure the replacement component maintains the same form factor for PCB compatibility.
