Balun Procurement Notes

Verify the specific impedance matching requirements against your schematic, as this component provides 50/100 Ohm transformation. Confirm that the PCB land pattern strictly adheres to the 0202 (0505 metric) dimensions to ensure proper solder joint formation. Check for any specific handling instructions regarding the small form factor during assembly.

Balun Selection Notes

Select this component when a miniature balun is required for sub-3 GHz wireless standards. Ensure the operating frequency aligns with the 2.3–2.69 GHz range. Consider the 50/100 Ohm impedance ratio if interfacing between standard RF lines and differential antenna ports. Evaluate the physical size constraints against the 0.6x0.5x0.25 mm package.
