Ptc Resettable Fuses datasheet and documents for RS30-090

RS30-090

Ptc Resettable Fuses Overview

The OptiFuse RS30-090 is a polymeric PTC resettable fuse designed for through-hole radial mounting. It features a maximum voltage rating of 30V and a hold current (Ih) of 900mA. The device operates within an operating current range of 900mA to 9A. Key electrical parameters include a minimum resistance of 70mΩ and a maximum resistance of 220mΩ. It has a maximum current rating of 100A and a switched current of 1.8A. The component dissipates up to 0.6W of power.

Ptc Resettable Fuses Feature Summary

Solid-state radial leaded construction for reliable circuit protection
Low resistance characteristics combined with high hold current capability
Polymer technology enabling automatic reset functionality after fault clearance

Ptc Resettable Fuses Applications

Electronic applications requiring overcurrent protection
Circuit protection in low-voltage systems
Automated assembly processes utilizing tape and reel packaging

Ptc Resettable Fuses Procurement Notes

Verify the specific package configuration, as the RS30 series is available in both loose components and tape-and-reel formats for automated assembly. Confirm that the 30VDC rating aligns with your system's maximum operating voltage. Ensure the 900mA hold current meets the continuous load requirements without nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, through-hole resettable fuse is required. The 900mA hold current suits circuits with steady-state loads near this value. Consider the 70mΩ to 220mΩ resistance range for impact on circuit efficiency. The radial lead style facilitates manual or wave soldering integration into PCB designs.

Ptc Resettable Fuses Part Context

The RS30-090 belongs to the OptiFuse RS30 series, which provides high hold currents up to 9A with low voltage ratings up to 30V. This series utilizes polymeric PTC technology to offer reusable overcurrent protection. The radial lead package allows for standard through-hole mounting techniques in various electronic assemblies.
