Balun Procurement Notes

Verify component status as not recommended for new designs due to potential minimum order quantity restrictions. Confirm packaging type availability including tape and reel, cut tape, or Digi-Reel options. Ensure compliance with RoHS3 standards and check for any recent product change notices affecting lead times or specifications before finalizing procurement plans.

Balun Selection Notes

Select this component when a compact 0603 footprint is required for 791-960MHz balun functionality. Consider the 1.2dB insertion loss and -10dB return loss limits against system budget requirements. Verify that the 50/100 Ohm impedance ratio aligns with the specific circuit topology needs for balanced-to-unbalanced conversion in the target application environment.
