Ptc Resettable Fuses Procurement Notes

Verify that the specific part number suffix matches the required reel or cut tape packaging configuration for your assembly line. Confirm that the thermal environment of the application remains within the specified -40°C to +85°C operational limits to ensure reliable tripping characteristics. Ensure that the PCB footprint aligns with the 1812 package dimensions to prevent mechanical stress during soldering.

Ptc Resettable Fuses Selection Notes

Select this component when the circuit requires a 30 VDC rating and a holding current near 350 mA. Consider the 1812 package size if space constraints allow for larger components compared to smaller SMD footprints. Evaluate the 1 Ohm typical resistance impact on signal integrity or power loss in low-voltage applications before finalizing the design choice.
