LFCN-2952+

Overview

The LFCN-2952+ is a low-pass filter manufactured by Mini-Circuits using Low-Temperature Co-fired Ceramic (LTCC) technology. It provides a frequency range from DC to 29,500 MHz with a cutoff at 31 GHz. The component features a 50Ω impedance rating and is housed in an FV1206-11 case style, corresponding to the 1206 surface-mount package.

Feature Summary

• Utilizes LTCC construction for mm-wave frequency operation
• Provides good stopband rejection characteristics
• Designed for compact integration in small form factors

Applications

• WiFi systems
• Bluetooth applications
• Zigbee networks

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the '+ suffix' indicates lead-free compliance if required by your assembly process. Ensure the receiving facility has appropriate ESD protection protocols for handling SMT components.

Selection Notes

Select this component when a sharp cutoff near 30 GHz is required in a minimal footprint. The LTCC material offers stability suitable for high-frequency environments. Compare insertion loss and stopband attenuation against other LFCN series variants to ensure compatibility with your specific RF chain requirements.

Part Context

This part belongs to the LFCN series of miniature low-pass filters. These components are engineered for high performance in dense circuit boards. The series typically covers various cutoff frequencies while maintaining consistent impedance and package dimensions for design flexibility across different product lines.

Replacement Considerations

Check for direct substitutes within the LFCN series with similar cutoff frequencies. Verify pinout compatibility and thermal characteristics before swapping. No specific alternative part numbers are confirmed in the provided documentation.
