Balun Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS standards and lead-free requirements. Confirm that the 1206 package dimensions align with the target PCB footprint. Cross-reference the manufacturer part number against official Murata documentation to distinguish this variant from other LDB series components with different impedance or frequency specifications.

Balun Selection Notes

Select this component when a 50 Ohm to 200 Ohm impedance transformation is required within the 1.7–1.9 GHz range. Ensure the design accommodates the 1206 surface-mount form factor. Consider the multilayer hybrid construction for stability in high-frequency environments. Validate that the application does not require alternative impedance ratios or frequency bands covered by other LDB series variants.
