Ptc Resettable Fuses Procurement Notes

Verify RoHS compliance status prior to integration, as this specific part number is explicitly listed as non-compliant. Confirm that the 50V voltage rating and 80mA hold current align with the target circuit requirements. Ensure the radial through-hole package fits the PCB layout constraints. Check for active production status or obsolescence warnings before finalizing procurement plans.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse with a 50V maximum rating and 80mA hold current is required. The 100 Ohm resistance at 25°C suits low-power signal lines. Consider the physical size of 10.20 mm diameter for available board space. Verify compatibility with the operating temperature range defined in the official datasheet.

Ptc Resettable Fuses Part Context

This part is part of the PTF series from Amphenol Advanced Sensors (Thermometrics), specializing in polymer PTC devices. These components serve as reusable alternatives to traditional fuses, offering protection against overcurrent conditions without requiring manual replacement after tripping events.
