Ptc Resettable Fuses Procurement Notes

Verify the specific suffix HTE against official Vishay documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the ordering part number matches the exact resistance value and voltage rating required for the target application circuit design.

Ptc Resettable Fuses Selection Notes

Select this component when a 12-ohm holding current characteristic is required for thermal resettable fusing applications. Confirm that the operating environment stays within the specified 0°C to +70°C range and that the PCB layout accommodates the 15.5 mm axial length for proper clearance and heat dissipation.

Ptc Resettable Fuses Part Context

This part is classified under Vishay's radial PTC thermistor portfolio, distinct from surface-mount or high-voltage series variants. It serves as a reusable alternative to traditional fusible links, offering resettable protection capabilities for low-to-medium current circuits where space constraints favor through-hole radial packages.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other Vishay PTCCL series parts sharing identical 12-ohm resistance and radial form factor. Verify that substitute components match the specific voltage rating and maximum operating temperature limits defined in the official datasheet.
