Procurement Notes

Verify the current production status before procurement, as this part is designated as not recommended for new designs. Confirm that existing inventory or legacy supply chains can meet project requirements. Ensure compatibility with existing PCB layouts due to the specific 0402 footprint. Review official datasheets for any updated handling or soldering specifications relevant to this component type.

Selection Notes

Select this component only for maintenance or legacy system upgrades where the original design specifies this exact part number. Evaluate alternative components if starting a new design, given its discontinued status. Consider the 50-ohm impedance match and 0402 size constraints during integration. Verify that the 700 MHz to 3800 MHz passband aligns with the target application's frequency requirements.
