Procurement Notes

Verify the exact suffix designation against the manufacturer's official datasheet to confirm terminal plating and packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the part number with authorized distributors to confirm authenticity and traceability before procurement.

Selection Notes

Select this component when space constraints require a 0603 footprint while maintaining a 3 A current handling capability. The 80 Ohm impedance at 100 MHz makes it suitable for suppressing noise in digital signal lines. Consider the flexible termination feature if the application involves significant thermal cycling or mechanical vibration that could stress rigid terminations.
