Procurement Notes

Verify the specific impedance value and material designation against the manufacturer's current datasheet before integration. Confirm that the physical dimensions match the cable bundle requirements. Ensure compliance with relevant environmental regulations such as RoHS for the intended market. Check for any updates to the part number suffix or packaging specifications.

Selection Notes

Select this component when Material 46 characteristics are required for the target frequency range. Ensure the cable diameter fits within the 10.15 mm inner diameter constraint. Consider the thermal operating limits if the application involves high ambient temperatures. Compare with other materials in the 26 series if different impedance profiles are needed.

Part Context

This part belongs to Fair-Rite's 26 series of ferrite cable cores, which offers various shapes and materials for EMI suppression. The 2646626402 specifically uses Material 46, distinct from common Materials 31 or 43.
