RUE110

Ptc Resettable Fuses Overview

The Littelfuse RUE110 is a polymeric PTC resettable fuse from the PolySwitch series, designed for through-hole radial mounting. It features a hold current of 1.1 A and a maximum voltage rating of 30 VDC. The device has a trip current of 2.2 A and a maximum interrupt rating (Imax) of 40 A. Its initial resistance is typically 0.06 ohms, with a maximum of 0.2 ohms. The component operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions by increasing resistance upon heating.
• Utilizes polymeric technology for reliable resettable performance after fault clearance.
• Designed for through-hole PCB mounting with radial leads for secure mechanical attachment.

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified supply chain partners. Confirm that the received part matches the RUE110 designation and exhibits no physical damage. Ensure storage conditions comply with manufacturer guidelines to maintain material integrity prior to assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a 1.1 A hold current and 30 VDC rating align with circuit requirements. Consider the radial package for through-hole assembly processes. Evaluate thermal environment constraints to ensure operation remains within the specified -40°C to +85°C range during normal and fault conditions.

Ptc Resettable Fuses Part Context

The RUE110 belongs to the PolySwitch family of self-recovery fuses, offering a reusable alternative to traditional one-time fusible links. This series is engineered for applications requiring repeated overload protection without manual replacement, supporting robust system reliability in consumer and industrial electronics.

Ptc Resettable Fuses Replacement Considerations

The RUE110-2 is a documented variant within the same product line. Verify compatibility regarding lead spacing and packaging format before substitution. Cross-reference datasheet parameters to ensure electrical ratings meet specific application needs.
