Balun Procurement Notes

Verify the lifecycle status before procurement, as this component is marked as Not For New Designs. Confirm RoHS3 compliance requirements against current project specifications. Ensure the 0805 footprint matches the target PCB layout. Validate that the 942 MHz operating frequency aligns with the system's RF requirements. Check for any specific handling instructions regarding the multi-layer hybrid structure during assembly.

Balun Selection Notes

Select this component when a 100 Ohm impedance balun is required at 942 MHz. The 0805 package size suits space-constrained designs. Consider the +85°C thermal limit for environmental compatibility. Evaluate the multi-layer hybrid technology for its specific RF characteristics compared to other balun types. Ensure the application does not require new design inclusion due to lifecycle restrictions.
