LFCW-5000+

Overview

The LFCW-5000+ is an LTCC low pass filter from Mini-Circuits with a passband from DC to 5000 MHz. It features a 50 ohm impedance and operates within a temperature range of -55°C to +100°C. The component utilizes a 0603 (1608 metric) SMD package, specifically case style JC0603C-1. It provides 1.6 dB insertion loss in the passband and offers attenuation up to 5.75 GHz. Designed for signal conditioning, it supports applications requiring compact, high-performance filtering solutions.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides effective signal attenuation above the 5000 MHz cutoff frequency
• Designed for surface mount integration in compact circuit layouts

Applications

• RF signal conditioning
• Harmonic suppression
• Base station filtering

Procurement Notes

Verify the specific datasheet version for precise electrical characteristics such as return loss and group delay. Confirm that the 0603 package dimensions align with your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles for LTCC components. Check for any specific handling instructions regarding moisture sensitivity levels before assembly.

Selection Notes

Select this component when a sharp cutoff near 5 GHz is required in a minimal footprint. The LTCC construction offers stability across wide temperature variations compared to other technologies. Consider the 1.6 dB insertion loss impact on system noise figure. The 50 ohm impedance matches standard RF transmission lines without additional matching networks.
