LFCN-6400D+

Overview

The LFCN-6400D+ is a surface-mount low-pass filter manufactured by Mini-Circuits, designed for RF and microwave applications up to 6400 MHz. It features a 50 Ohm impedance and utilizes ceramic technology in a compact SMD3216-4P package. The component provides an insertion loss of 2 dB and offers high attenuation characteristics suitable for signal filtering tasks.

Feature Summary

• Surface mount construction for automated assembly
• Ceramic dielectric material for stability
• Low insertion loss performance
• High attenuation beyond cutoff frequency

Applications

• RF signal conditioning circuits
• Harmonic suppression in transmitters
• Interference filtering in communication systems

Procurement Notes

Verify the specific suffix D+ against the manufacturer's current datasheet to confirm pinout and tolerance specifications. Ensure compatibility with standard reflow soldering profiles for the SMD3216-4P package. Cross-reference impedance ratings with system requirements before integration.

Selection Notes

Select this component when a compact, low-loss low-pass filter is required for frequencies up to 6.4 GHz. The ceramic construction offers thermal stability, while the small footprint suits space-constrained PCB designs. Verify that the 2 dB insertion loss meets system budget constraints.

Part Context

This part belongs to Mini-Circuits' LFCN series of ceramic low-pass filters. These components are engineered for broadband RF applications requiring reliable performance in a miniature surface-mount format. The series supports various cutoff frequencies tailored for different microwave bands.

Replacement Considerations

Consult Mini-Circuits documentation for direct equivalents or alternative models within the LFCN series. Verify that any substitute matches the 50 Ohm impedance, SMD3216-4P package dimensions, and cutoff frequency specifications.
