LFCN-3400+

Overview

The LFCN-3400+ is a low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications. It features an LTCC construction with a cutoff frequency of 3400 MHz and operates within a 50Ω system. The device supports frequencies from DC to 3950 MHz and utilizes a compact FV1206 case style. This component provides excellent power handling capabilities and is suitable for RF signal conditioning in high-frequency circuits.

Feature Summary

• LTCC ceramic construction for reliable surface-mount integration
• Designed for low-pass filtering applications up to 3950 MHz
• Optimized for 50Ω impedance systems
• Compact FV1206 package footprint

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in microwave circuits
• Base station front-end filtering
• Test and measurement equipment input stages

Procurement Notes

Verify the specific suffix (e.g., D+) if tape and reel packaging is required, as standard versions may differ. Confirm the FV1206 case style matches your PCB layout constraints. Ensure the 50Ω impedance specification aligns with your system design requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-pass filter with a 3400 MHz cutoff is needed in a compact SMT form factor. The LTCC technology offers stability for RF applications. Consider the FV1206 dimensions for space-constrained designs requiring 50Ω performance without discrete components.

Part Context

Mini-Circuits produces a broad range of RF and microwave components. The LFCN series specifically addresses low-pass filtering needs using LTCC technology. This model fits into their portfolio of surface-mount filters designed for modern electronic devices requiring miniaturization and high-frequency performance.

Replacement Considerations

Check for LFCN-3400D+ for tape and reel availability. Verify electrical parameters against other Mini-Circuits LTCC filters if sourcing alternatives. Ensure mechanical compatibility with the FV1206 footprint when considering substitutes.
