RS90-035

Ptc Resettable Fuses Overview

The OptiFuse RS90-035 is a polymeric PTC resettable fuse designed for circuit protection. It features a hold current (Ih) of 350 mA and a trip current (It) of 750 mA. The device operates with a maximum voltage rating of 72 VDC, with an internal rating of 90 VDC. It has an interrupt rating of 40 A at 90 V DC. The component utilizes a radial lead through-hole mounting style in a disc package.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC technology provides automatic reset functionality after fault clearance.
• Radial lead disc package enables standard through-hole mounting.
• Rated for 40 A interrupt capacity to handle high fault currents safely.

Ptc Resettable Fuses Applications

• Electronic applications requiring overcurrent protection
• Circuit protection for low-voltage DC systems

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet version for the RS90-035 to confirm exact resistance values and thermal characteristics. Ensure the application voltage does not exceed the 72 VDC rating. Confirm that the radial lead pitch matches the target PCB layout requirements before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a 350 mA hold current is required for DC circuits up to 72 V. Consider the 750 mA trip threshold for fault detection sensitivity. The radial disc form factor is suitable for manual assembly or wave soldering processes where surface-mount alternatives are not feasible.

Ptc Resettable Fuses Part Context

This part belongs to the OptiFuse RS90 series of resettable fuses. The series offers various current ratings ranging from 100 mA to 3.75 A. The RS90-035 specifically addresses mid-range current protection needs within this family, sharing common packaging and interrupt rating specifications with other variants.

Ptc Resettable Fuses Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 350 mA hold current, 72 VDC voltage rating, and radial lead package dimensions precisely.
