Balun Procurement Notes

Verify the specific suffix -300 against official Murata documentation to confirm the exact frequency tolerance and impedance matching characteristics. Confirm RoHS compliance status through current manufacturer declarations. Check lifecycle status as some sources indicate obsolescence. Ensure the 1206 package dimensions match your PCB footprint requirements before procurement.

Balun Selection Notes

Select this component when a 50 Ohm to 50 Ohm balun is required for the 1800-2000 MHz range. The 1206 package offers a balance between performance and board space. Consider thermal management if operating near maximum temperature limits. Verify that the multi-layer hybrid construction meets the environmental reliability standards of the target application.
