LFCN-80+

Overview

The LFCN-80+ is an LTCC low pass filter designed for operation from DC to 80 MHz with a 50Ω impedance. It utilizes a compact FV1206 surface-mount package, integrating ceramic dielectric resonators and thin-film metallization on alumina substrates. The component provides high attenuation above the cutoff frequency while maintaining low insertion loss in the passband. It is engineered for stability across temperature variations and offers reliable performance in RF signal processing applications requiring precise frequency filtering.

Feature Summary

• Utilizes LTCC technology for robust construction and thermal stability
• Provides sharp roll-off characteristics for effective harmonic suppression
• Designed for surface-mount integration in space-constrained PCB layouts

Applications

• RF front-end filtering in communication systems
• Harmonic suppression in signal generators
• Interference rejection in test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and electrical parameter tables provided by Mini-Circuits before finalizing design specifications. Confirm that the FV1206 footprint matches your PCB layout requirements. Ensure environmental ratings align with your operational conditions. Cross-reference part numbers to distinguish between standard and specialized variants if necessary.

Selection Notes

Select this component when a low-pass response up to 80 MHz is required within a minimal footprint. Consider the LTCC construction for applications demanding durability and consistent performance over temperature ranges. Evaluate insertion loss and stopband attenuation requirements against the official datasheet graphs to ensure compatibility with system noise budgets.

Part Context

This component belongs to the LFCN series of ceramic low-pass filters manufactured by Mini-Circuits. The series leverages Low-Temperature Co-fired Ceramic (LTCC) technology to achieve high performance in small packages. The '+' suffix typically denotes lead-free compliance or updated manufacturing standards compared to older versions like the LFCN-80.

Replacement Considerations

Direct substitutes may include other Mini-Circuits LTCC low-pass filters with similar cutoff frequencies and package styles. Verify impedance matching and physical dimensions before swapping. Consult official cross-reference guides for confirmed equivalent part numbers.
