Procurement Notes

Verify the specific suffix Z indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status matches current regulatory requirements. Ensure the supplier provides original manufacturer documentation to validate material grade 4S2 specifications. Check lead time availability as components may be subject to production schedules.

Selection Notes

Select this component where low insertion loss and high saturation current are critical. The 4S2 material offers stable performance across varying temperatures. Compare impedance characteristics against target frequency spectra to ensure adequate attenuation. Verify footprint compatibility with existing PCB silkscreen and copper pad designs before finalizing the bill of materials.
