Procurement Notes

Verify the specific suffix designation when ordering, as variations such as 'S' may indicate different packaging or minor physical attributes not detailed in the base datasheet. Confirm that the standard bulk or tray packaging aligns with assembly requirements. Ensure the operating temperature range meets the environmental conditions of the target application before finalizing procurement.

Selection Notes

Select this component for applications requiring quick installation on cables with a 5 mm diameter. The 98 Ohm impedance at 25 MHz makes it suitable for general EMI suppression tasks. Consider the physical dimensions and weight constraints of the enclosure. Verify compatibility with the safety key mechanism if manual handling tools are not used during assembly.
