Balun Procurement Notes

Verify the specific suffix KK81 corresponds to the required surface-mount tape-and-reel packaging configuration. Confirm that the 50-ohm impedance rating aligns with the system design requirements. Ensure the operating frequency range covers the intended signal bandwidth without degradation. Cross-reference the datasheet electrical specifications against the application's isolation and insertion loss constraints before finalizing procurement.

Balun Selection Notes

Select this component when a 1:2 ratio transformer is required for frequencies up to 200 MHz. The KK81 package is appropriate for surface-mount assembly lines. Consider the core and wire construction for its balance of performance and size. Verify compatibility with the target circuit's impedance levels. Evaluate the physical dimensions against available PCB space constraints.

Balun Part Context

This part belongs to Mini-Circuits' TC and ADT series of RF baluns and transformers. These components are engineered for professional signal conversion tasks.
