RLD30P600UF

Ptc Resettable Fuses Overview

The Littelfuse RLD30P600UF is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 6 A and a maximum voltage rating of 30 V DC. The component utilizes through-hole radial mounting with a lead spacing of 10.20 mm. It exhibits a trip time of 16 seconds under fault conditions and supports a maximum current of 40 A. The device operates within a temperature range of -40 °C to 85 °C and has a resistance of 0.01 to 0.05 ohms at 24 °C.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault clearance without manual replacement
• Offers bidirectional protection against overcurrent and thermal hazards
• Maintains low resistance during normal operation to minimize power loss

Ptc Resettable Fuses Applications

• Low voltage DC power supply circuit protection
• Portable electronic device battery protection
• Consumer electronics overcurrent safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix (e.g., UF) matches the required packaging and compliance specifications, as Littelfuse part numbers often denote distinct handling or regulatory attributes. Confirm that the radial leaded package aligns with the target PCB layout requirements. Ensure the 30 VDC rating is sufficient for the application's peak operating voltage to prevent premature tripping or failure. Cross-reference the hold current and trip characteristics against the system's operational profile to guarantee reliable performance under expected load conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable solution is preferred over traditional fuses to reduce maintenance costs and downtime. The 6 A hold current suits moderate load applications requiring robust surge tolerance. Consider the 10.20 mm lead spacing for compatibility with standard through-hole assembly processes. Evaluate the thermal environment to ensure the 85 °C maximum operating temperature meets the system's ambient requirements. This device is suitable for applications where space constraints preclude larger industrial fuses but require reliable protection.

Ptc Resettable Fuses Part Context

The RLD30 series represents Littelfuse’s line of radial leaded polymeric PTC resettable fuses. These components are engineered for general-purpose circuit protection in consumer and industrial electronics. The series offers a balance of high holding current capability and compact form factor. They serve as alternatives to conventional fusible links, providing reusable protection against accidental overcurrent events in low-voltage DC systems.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 30V 6A radial PTC fuses from manufacturers such as Bourns or EAO, provided the lead spacing and trip characteristics match. Verify that any replacement maintains the same voltage rating and hold current to ensure equivalent circuit protection levels.
