LFCG-490+

Overview

The LFCG-490+ is an LTCC low pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It provides a passband from DC to 490 MHz with excellent stopband rejection up to 590 MHz. The component operates at a characteristic impedance of 50Ω and exhibits an insertion loss of 2 dB. It utilizes a compact GE0805C-2 surface mount package, specifically an 8-pad SMD/SMT configuration in the 0805 (2012 Metric) case style.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides high stopband rejection to eliminate high-frequency noise and unwanted signals
• Features a compact surface mount design suitable for space-constrained PCB layouts

Applications

• RF and microwave circuit filtering
• High-frequency noise elimination
• Unwanted signal suppression in communication systems

Procurement Notes

Verify the specific datasheet version and electrical characteristics directly from Mini-Circuits official documentation before integration. Confirm that the GE0805C-2 footprint matches your PCB layout requirements. Ensure compatibility with your system's 50Ω impedance environment. Cross-reference the part number LFCG-490+ to avoid confusion with similar frequency variants in the LFCG series.

Selection Notes

Select this component when a low pass filter with a cutoff near 490 MHz is required. The LTCC construction offers stability compared to other ceramic types. Consider the 0805 package size for assembly constraints. Verify that the 2 dB insertion loss meets your link budget requirements. Ensure the operating frequency range aligns with the DC to 490 MHz specification.

Part Context

This component belongs to the LFCG series of LTCC filters from Mini-Circuits. These filters are engineered for general-purpose RF applications requiring reliable performance in a small form factor. The series typically includes various cutoff frequencies, with the LFCG-490+ specifically targeting the sub-500 MHz range. It represents a standard solution for integrating filtering capabilities into modern electronic devices.
