RS60SB-110

Ptc Resettable Fuses Overview

The OptiFuse RS60SB-110 is a polymeric PTC resettable fuse designed for circuit protection. It features radial leads and operates at a maximum voltage of 60V with a trip current of 1.1A. The device has a maximum interrupting current (Imax) of 40A. Electrical resistance ranges from a minimum of 170mΩ to a maximum of 470mΩ. It dissipates 2.2W of power and functions within an operating temperature range of -40°C to 85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic resettable overcurrent protection using polymeric technology
• Radial leaded construction facilitates through-hole mounting
• Capable of handling high fault currents up to 40A

Ptc Resettable Fuses Applications

• Electronic applications requiring frequent overcurrent conditions
• Circuits demanding constant uptime without manual fuse replacement
• General circuit protection in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix matches the required hold current, as variations exist within the RS60SB series. Confirm RoHS compliance status if restricted substances are a concern. Check packaging options such as bulk or reel/tape formats against assembly requirements. Ensure the 60V rating aligns with the system voltage. Validate that the 1.1A trip current suits the protected circuit's normal operating limits.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable solution is preferred over traditional fuses to maintain system availability. The 60V rating limits suitability to low-voltage DC circuits. Consider the 1.1A trip point relative to the load's peak current to prevent nuisance tripping. The radial lead style requires PCB layouts compatible with through-hole technology. Evaluate thermal derating requirements if ambient temperatures approach the upper limit.

Ptc Resettable Fuses Part Context

This part belongs to the OptiFuse RS60SB series of resettable fuses. The series includes variants with different hold currents, such as the RS60SB-050, RS60SB-065, and RS60SB-135. All share similar voltage ratings and package styles but differ in trip characteristics. The RS60SB-110 specifically targets applications needing 1.1A protection.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other RS60SB series parts like RS60SB-090 or RS60SB-135 if current ratings can be adjusted. Cross-brand replacements require matching 60V, radial lead, and PTC polymer specifications. Verify that alternative components meet the same Imax and resistance criteria.
