RUSBF160

Ptc Resettable Fuses Overview

The Littelfuse RUSBF160 is a radial-leaded PPTC resettable fuse designed for circuit protection. It features a polymeric construction with a hold current of 1.6A and a trip current of 3.2A. The device operates at a maximum voltage of 16V and can withstand a maximum fault current of 40A. It utilizes a disc package configuration suitable for through-hole mounting.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient (PPTC) technology for automatic reset functionality
• Radial leaded disc package for standard through-hole assembly
• High fault current capability to handle surge events without permanent damage

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Protection for USB peripheral connections
• Battery pack circuit safeguarding
• Consumer electronics power input lines

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet version corresponding to the RF3394-000 or RUSBF160 designation to ensure alignment with required electrical ratings. Confirm that the radial lead form factor matches the target PCB layout requirements. Cross-reference the manufacturer's official documentation for any updates regarding compliance standards or recommended soldering profiles to guarantee reliable long-term performance in the final assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a self-resetting overcurrent solution is preferred over traditional one-time fuses. Ensure the operating environment remains within the specified voltage and current limits to prevent unintended tripping. Consider the thermal management requirements, as the device resistance increases significantly during a fault state, potentially affecting nearby components if not properly spaced on the board.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse PolySwitch RUSBF series, which provides a comprehensive range of PPTC resettable fuses. The series is characterized by its radial-leaded design, offering a cost-effective and space-efficient alternative to surface-mount options for applications requiring robust circuit protection in consumer and industrial electronics.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1.6A hold current, 16V rating, and radial package. Verify that alternative PPTC devices from other manufacturers meet the same 40A maximum fault current specification and maintain compatible thermal characteristics for seamless integration.
