LFCN-120+

Overview

The LFCN-120+ is a ceramic low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It operates from DC to 120 MHz with a 50Ω impedance. The component utilizes LTCC technology and is housed in an FV1206 surface-mount package (SMD-4P, 3.2x1.6mm). It features a 1dB bandwidth of 120 MHz.

Feature Summary

• LTCC construction for compact surface-mount integration
• Low-pass filtering characteristic up to 120 MHz
• 50Ω system impedance compatibility

Applications

• RF signal conditioning
• Harmonic suppression
• Base station front-end filtering

Procurement Notes

Verify the specific datasheet version and environmental rating (ENV06) against project requirements. Confirm that the FV1206 footprint matches the PCB layout design. Ensure the operating temperature range aligns with the intended application environment before finalizing procurement.

Selection Notes

Select this component when a low-pass filter with a cutoff frequency near 120 MHz is required in a space-constrained design. The LTCC technology offers reliability for high-volume manufacturing. Verify insertion loss and stopband attenuation specifications in the full datasheet to ensure compliance with system noise and interference budgets.

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 harmonic rejection and noise filtering in compact surface-mount packages suitable for modern electronic assemblies.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Do not assume functional equivalence with generic LTCC filters without cross-referencing electrical specifications and physical dimensions.
