LFCG-320+

Overview

The LFCG-320+ is a low-pass filter manufactured by Mini-Circuits, utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It operates with a passband from DC to 320 MHz and features a characteristic impedance of 50Ω. The component is housed in an SMT package designated as GE0805C-2, corresponding to the 0805 (2012 Metric) case style with an 8-pad configuration. It supports surface mount mounting types and has a maximum operating temperature of +100°C.

Feature Summary

• Utilizes LTCC construction for compact surface mount integration
• Provides signal filtering within a DC to 320 MHz frequency range
• Designed for 50Ω system impedance compatibility

Applications

• RF signal conditioning circuits
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be hosted on distributor platforms. Confirm that the ordering suffix matches the required variant, noting that suffixes typically indicate packaging or minor physical differences rather than functional changes. Ensure the procurement channel provides official Mini-Circuits documentation to validate the LTCC specifications and electrical performance data.

Selection Notes

Select this component when a low-pass filter with a cutoff near 320 MHz is required for RF applications. The choice depends on the need for LTCC technology benefits, such as size reduction and thermal stability, alongside the specific 0805 footprint constraint. Verify that the 50Ω impedance aligns with the system design requirements before finalizing the selection.

Part Context

This part belongs to the Mini-Circuits LFCG series of LTCC low-pass filters. These components are engineered for high-performance RF applications requiring precise frequency control. The series utilizes ceramic materials to achieve stable electrical characteristics in a small form factor, distinguishing it from traditional lumped-element or waveguide filters.

Replacement Considerations

The VLFG-320+ is listed as a related model with identical electrical specifications but may differ in connector types or physical housing. Verify mechanical compatibility if replacing the standard SMT version with a connectorized variant.
