Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be hosted by distributors. Confirm that the received components match the 3-4-6WL part number exactly. Ensure compliance with lead-free and RoHS requirements if specified for your assembly process. Cross-reference the package type to confirm the 6-SMD gull wing configuration before integration.

Selection Notes

Select this component when a compact solution for RF balancing is required within the 20 kHz to 200 MHz range. The surface-mount gull wing design offers improved mechanical stability compared to through-hole alternatives during thermal stress. Consider its physical footprint and electrical characteristics against available alternatives to ensure compatibility with the target PCB layout and signal integrity requirements.

Part Context

This component belongs to the Bourns Inc. passive component portfolio, specifically focusing on magnetic devices for signal processing. It serves as a specialized transformer for converting differential signals to single-ended formats or vice versa. The product line emphasizes reliability in high-frequency environments, supporting various industrial and consumer electronics applications requiring precise signal transformation.

Replacement Considerations

Consult official Bourns documentation for direct cross-references. Verify that any substitute maintains the same 6-SMD gull wing package and operates within the identical 20 kHz to 200 MHz frequency range. Ensure electrical parameters such as impedance and insertion loss match the original design specifications to prevent signal degradation.
