RLD60P010XF

Ptc Resettable Fuses Overview

The Littelfuse RLD60P010XF is a PolySwitch resettable PTC fuse designed for overcurrent protection. It features a radial leaded through-hole package with a disk form factor. The device has a hold current of 0.1 A and a trip current of 0.2 A, operating at a maximum voltage of 60 VDC. Initial resistance is typically 0.47 ohms, rising significantly upon fault conditions. It supports a maximum fault current rating of 40 A and dissipates up to 0.5 W of power. The component operates within a temperature range of -40°C to +85°C and meets RoHS standards.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by increasing resistance as it heats during fault conditions
• Offers automatic circuit restoration without manual replacement after the fault clears
• Designed for general-purpose applications in automotive, telecom, and power supply circuits

Ptc Resettable Fuses Applications

• Protection of actuators, screens, and small motors in commercial and passenger vehicles
• Overcurrent protection for circuits, wiring harnesses, and PCB components
• General-purpose resettable fuses in consumer electronics and industrial equipment

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'XF' against the official Littelfuse datasheet to confirm lead configuration and packaging details. Ensure the selected variant matches the required hold and trip currents for the target application. Confirm RoHS compliance status if environmental regulations are strict. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Ptc Resettable Fuses Selection Notes

Select this component when a low-current, high-resistance resettable fuse is required for 60V DC systems. The radial leaded format is suitable for through-hole PCB mounting where space allows. Consider the thermal environment, as the trip time depends on ambient temperature. Compare initial resistance values against other series if voltage drop is critical. Ensure the fault current rating exceeds the system's prospective short-circuit current.

Ptc Resettable Fuses Part Context

This part belongs to the RLD60 series of PolySwitch resettable fuses from Littelfuse. The series is characterized by its 60V maximum voltage rating and radial leaded construction. These devices are solid-state alternatives to traditional fuses, offering repeated use after tripping. The RLD60 family is widely used in automotive and industrial applications requiring robust overcurrent protection.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes may include other RLD60 series variants with different current ratings, such as RLD60P020XF or RLD60P050XF, provided the electrical parameters match the circuit requirements. Cross-brand replacements require careful verification of hold current, trip current, and maximum voltage ratings to ensure equivalent protection levels.
