LFCG-1800+

Overview

The LFCG-1800+ is a low-pass filter manufactured by Mini-Circuits, utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It features a passband from DC to 1800 MHz and operates with a 50Ω impedance. The component provides an insertion loss of 1.1 dB within the passband. It is housed in an 0805 surface-mount package, specifically identified as case style GE0805C-2.

Feature Summary

• Constructs signal filtering using LTCC technology for compact integration
• Provides low-pass frequency response up to 1800 MHz
• Designed for surface-mount installation in space-constrained circuits

Applications

• Automotive electronic devices
• RF signal conditioning
• Power supply regulation and control systems

Procurement Notes

Verify the specific datasheet version and revision history before procurement. Confirm that the 0805 footprint matches the target PCB layout. Ensure the LTCC construction meets environmental requirements. Check for any product change notices affecting electrical characteristics or packaging specifications.

Selection Notes

Select this component when a DC-to-1800 MHz low-pass response is required in a minimal footprint. The LTCC construction offers stability suitable for various environments. Consider the 1.1 dB insertion loss impact on system gain. Verify compatibility with standard SMT assembly processes for the 0805 case style.

Part Context

This part belongs to the LFCG series of ceramic filters from Mini-Circuits. The series utilizes LTCC technology to provide reliable RF filtering solutions. The LFCG-1800+ specifically targets applications requiring cutoff frequencies around 1800 MHz in a small form factor.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' LTCC filters without detailed parameter matching.
