LFCN-3000+

Overview

The LFCN-3000+ is a low-pass filter from Mini-Circuits designed for surface mount applications. It operates within a frequency range of 0 Hz to 3000 MHz and features a 50-ohm impedance. The component utilizes LTCC technology and is housed in an FV1206 package style, equivalent to the 0805 metric size. It supports SMD/SMT termination types and functions reliably between -40°C and +85°C.

Feature Summary

• LTCC construction for compact surface mount integration
• Low-pass filtering capability up to 3000 MHz
• 50-ohm system impedance compatibility

Applications

• RF signal conditioning
• Harmonic suppression
• Noise filtering in communication systems

Procurement Notes

Verify the specific suffix requirements against official datasheets before ordering. Confirm that the standard LFCN-3000+ variant meets your DC isolation needs, as it does not pass DC by default. If DC continuity is required, consider the 'D' suffix version. Ensure the FV1206 footprint matches your PCB layout constraints.

Selection Notes

Select this component when a compact, low-pass filter is needed for frequencies up to 3 GHz. The LTCC technology offers stability across the specified temperature range. Compare with the LFCG-3000+ if different packaging or specific electrical characteristics are preferred. Ensure the 50-ohm impedance aligns with your circuit design.

Part Context

This part belongs to the LFCN series of ceramic low-pass filters from Mini-Circuits. These components are engineered for RF and IF applications, providing effective attenuation above the cutoff frequency. The series includes variants like the LFCN-3000D+ for DC pass-through requirements.

Replacement Considerations

The LFCN-3000D+ is a confirmed substitute if DC pass-through functionality is required. Verify pinout and footprint compatibility with the FV1206 package before replacing.
