• Balanced to unbalanced signal conversion
• Surface mount 0402 footprint

Balun Applications

• Wireless LAN modules
• Bluetooth transceivers
• RF signal conditioning circuits

Balun Procurement Notes

Verify component authenticity through authorized TDK distributors or certified suppliers. Request official datasheets and test reports to confirm compliance with specified electrical parameters. Ensure storage conditions meet manufacturer requirements to maintain LTCC integrity prior to assembly.

Balun Selection Notes

Select this component for applications requiring precise impedance matching between 50-ohm single-ended and differential lines. The 0402 size suits high-density PCB layouts. Confirm operational frequency aligns with the 2400-2500 MHz band and that insertion loss limits meet system budget requirements.

Balun Part Context

This part belongs to TDK's LTCC balun family, optimized for RF front-end applications. It serves as a critical interface between baseband processors and RF power amplifiers or low-noise amplifiers in wireless communication devices operating at 2.4 GHz ISM bands.

Balun Replacement Considerations

Consult TDK documentation for direct equivalents. Verify pinout compatibility and electrical performance metrics before substituting with other manufacturers' baluns to ensure circuit stability.
