Ptc Resettable Fuses Procurement Notes

Verify that the required hold current of 4A and voltage rating of 16V DC align with the target circuit design. Confirm that the radial lead configuration matches the PCB footprint requirements. Ensure the operating temperature range of -40°C to 60°C meets the environmental specifications of the application. Check for compliance with relevant safety standards if applicable to the end product.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse with a 16V DC rating and 4A hold current is required. Consider the 6.8A trip current threshold to ensure proper sensitivity for the protected circuit. Evaluate the 100A maximum fault current capability against potential short-circuit scenarios. Compare the physical dimensions and radial lead style against available board space and assembly methods.

Ptc Resettable Fuses Part Context

The RS16-400 belongs to the OptiFuse RS16 series of polymeric PTC resettable fuses. This series is characterized by low voltage ratings up to 16V and high hold currents, making it suitable for specific low-voltage applications. The part utilizes a radial lead package format, which facilitates insertion into printed circuit boards for both manual and automated manufacturing processes.

Ptc Resettable Fuses Replacement Considerations

The Raychem-Tyco RGEF400 is identified as a cross-reference part for the RS16-400. Verify compatibility before substitution, as differences in trip characteristics or physical dimensions may exist between manufacturers.
