Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix and package variant against the official manufacturer datasheet before procurement. Confirm that the AEC-Q100 qualification status meets your project's automotive or industrial requirements. Ensure the radial disc package dimensions are compatible with your PCB layout constraints. Check for any recent lifecycle updates or obsolescence notices directly from Murata Electronics to avoid supply chain disruptions.

Ptc Resettable Fuses Selection Notes

Select this component when a 140V rating and approximately 400mA hold current are required for circuit protection. The 4.7-ohm initial resistance must be considered for low-voltage signal lines to prevent excessive voltage drop. Verify that the operating temperature range of -30°C to +85°C aligns with the environmental conditions of the target application. Ensure the radial through-hole form factor fits the available assembly space on the PCB.
