LFCG-42+

Overview

The Mini-Circuits LFCG-42+ is a low-pass filter utilizing LTCC technology, housed in an 0805 (2012 Metric) surface-mount package. It operates with a 50Ω impedance and provides a frequency range from DC to 435 MHz. The component features a cutoff frequency of 420 MHz and a bandwidth of 1.6 dB. It offers rejection up to 50 dB and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Compact 0805 surface-mount form factor for space-constrained designs
• High signal rejection capability up to 50 dB
• Wide operational frequency coverage from DC to 6100 MHz

Applications

• RF front-end filtering
• Signal integrity enhancement in communication systems
• Harmonic suppression

Procurement Notes

Verify the specific datasheet version and environmental rating (ENV06) prior to ordering. Confirm that the 0805 package dimensions align with your PCB layout constraints. Ensure the operating temperature range meets your system requirements. Cross-reference the part number suffix to confirm it matches the standard commercial grade specifications.

Selection Notes

Select this component when a compact low-pass filter is required for frequencies up to 435 MHz. The 50Ω impedance ensures compatibility with standard RF transmission lines. Consider the LTCC construction for stability and the small footprint for high-density board layouts. Evaluate the insertion loss and rejection characteristics against your specific signal spectrum needs.

Part Context

This component belongs to the LFCG series of low-pass filters from Mini-Circuits. The series is characterized by its use of LTCC technology and availability in small surface-mount packages. These filters are designed for general-purpose RF applications requiring reliable signal filtering in a minimal physical profile.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Do not assume interchangeability with other series without checking electrical parameters and pin configurations.
