LFCN-105+

Overview

The LFCN-105+ is a surface-mount LTCC low-pass filter manufactured by Mini-Circuits. It provides a passband from DC to 105 MHz with a nominal system impedance of 50 Ohms. The component utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust performance. It operates within a temperature range of -55°C to +100°C. The device is housed in an FV1206 case style and features SMT termination. It complies with RoHS and REACH standards.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) construction for high reliability
• Designed for surface mount integration into RF circuits
• Provides effective signal filtering from DC up to the specified cutoff frequency

Applications

• RF front-end filtering
• IF stage harmonic suppression
• General-purpose low-pass filtering in communication systems

Procurement Notes

Verify the specific datasheet version for precise insertion loss and rejection characteristics, as these values are critical for circuit design. Confirm that the FV1206 footprint matches the PCB layout requirements. Ensure the operating temperature range of -55°C to +100°C aligns with the environmental conditions of the final assembly. Check for any specific handling instructions related to the ceramic substrate.

Selection Notes

Select this component when a compact, surface-mount solution is required for frequencies up to 105 MHz. The 50 Ohm impedance rating makes it suitable for standard RF transmission lines. Consider the LTCC material properties for thermal stability. Evaluate the physical dimensions of the FV1206 package against available board space. Ensure the application does not require higher cutoff frequencies or different impedance levels.

Part Context

This part belongs to the LFCN series of ceramic low-pass filters from Mini-Circuits. These components are designed for use in RF and IF applications where size and performance are priorities. The series offers various cutoff frequencies while maintaining consistent packaging and electrical characteristics across the lineup.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Cross-referencing requires matching impedance, cutoff frequency, and package type. Generic equivalents may not replicate the specific LTCC performance characteristics.
