250S130-RADR

Ptc Resettable Fuses Overview

The Littelfuse Inc. 250S130-RADR is a resettable fuse, specifically a PolySwitch PPTC device, designed for overcurrent protection in electronic circuits. It features a hold current of 13.0 A and a trip current of 26.0 A at 25°C ambient temperature. The device has a maximum voltage rating of 30 V DC and a maximum fault current capability of 100 A. It operates within a temperature range of -40°C to +85°C and utilizes a radial leaded package configuration suitable for through-hole mounting applications.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault conditions clear without manual replacement
• Offers dual-element protection combining fast response with high surge tolerance
• Maintains low resistance state during normal operation to minimize power loss

Ptc Resettable Fuses Applications

• Portable computer peripheral protection
• Battery pack overcurrent safeguarding
• Consumer electronics circuit protection

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix RADR corresponds to the required tape and reel packaging format rather than bulk or axial variants. Confirm that the thermal environment of the target application does not exceed the derating curves provided in the official datasheet to ensure reliable tripping behavior under sustained load conditions.

Ptc Resettable Fuses Selection Notes

Select this component based on the system's nominal operating current being below the 13.0 A hold current threshold while ensuring transient surges remain within the 100 A fault current limit. Evaluate the PCB layout for adequate spacing to accommodate the radial leads and consider thermal dissipation requirements given the 30 V maximum voltage rating.

Ptc Resettable Fuses Part Context

This part belongs to Littelfuse's 250 Series of Radial Lead Resettable Fuses, which are engineered for high-current applications requiring robust overcurrent protection. The series is characterized by its ability to withstand repeated cycling and its compact form factor suitable for dense board layouts.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 13.0 A hold current, 30 V rating, and radial leaded package type. Verify equivalent I²t values and trip times from competing manufacturers' datasheets to ensure comparable performance characteristics.
