RS60RB-075

Ptc Resettable Fuses Overview

The OptiFuse RS60RB-075 is a polymeric resettable fuse (PTC) designed for overcurrent protection in circuits operating at maximum voltages of 60 VDC. It features a radial leaded, through-hole construction with a round body and tin-plated copper leads. Key electrical parameters include a hold current of 750 mA, a trip current of 1.5 A, and a maximum interrupting rating of 40 A. The device exhibits an initial resistance of approximately 600 mOhms and operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection through automatic circuit interruption upon excessive heat generation.
• Features a self-resetting mechanism that restores conductivity after the fault condition is removed and the device cools down.
• Utilizes a radial leaded package design suitable for standard printed circuit board mounting applications.

Ptc Resettable Fuses Applications

• Protection of portable electronic devices and battery packs from overcurrent conditions
• Overcurrent safeguarding in telecommunications equipment and data line interfaces
• Circuit protection for automotive electronics and accessories

Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number RS60RB-075 with official Littelfuse or OptiFuse documentation. Confirm RoHS compliance status and specific packaging configurations such as bulk or tape-and-reel quantities prior to acquisition. Ensure the supplier provides valid traceability records to guarantee product integrity and adherence to specified electrical standards.

Ptc Resettable Fuses Selection Notes

Select this component when circuit requirements specify a 750 mA holding current and a 60 VDC maximum voltage rating. Consider the 1.5 A trip current threshold for defining fault response sensitivity. Evaluate the physical dimensions and radial lead spacing to ensure compatibility with existing PCB layouts and assembly processes without requiring mechanical modifications.

Ptc Resettable Fuses Part Context

This model belongs to the RS60RB series of resettable fuses, which are characterized by their low profile and radial lead configuration. The series offers various current ratings to accommodate different circuit protection needs while maintaining a consistent form factor and voltage rating across the family.

Ptc Resettable Fuses Replacement Considerations

Equivalent components may include the Littelfuse 60R075XPR, which shares identical electrical specifications including 60V voltage rating, 750mA hold current, and radial lead packaging. Verify dimensional compatibility and lead material specifications before substitution.
