LFCW-5500+

Overview

The LFCW-5500+ is an LTCC low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications. It features a passband from DC to 5.5 GHz with a cutoff frequency of 6.32 GHz. The component operates at a standard 50-ohm impedance and utilizes a 0603 (1608 metric) package. It supports a minimum operating temperature of -55°C and a maximum of +100°C. The device provides 1.5 dB insertion loss and is RoHS compliant.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for stable performance
• Compact 0603 surface-mount form factor suitable for space-constrained designs
• Provides effective filtering of high-frequency harmonics and interference

Applications

• Wireless communication systems
• RF test equipment
• IoT terminals
• Industrial measurement and control

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's current documentation before procurement. Confirm that the 0603 footprint matches the target PCB design. Ensure environmental ratings meet the operational requirements of the final assembly. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this component when a compact low-pass filter is required for frequencies up to 5.5 GHz. The 50-ohm impedance makes it suitable for standard RF signal chains. Consider the LTCC construction for thermal stability in varying environments. Evaluate the 0603 package size against available board real estate constraints during the schematic capture phase.

Part Context

This component belongs to the LFCW series of LTCC low-pass filters from Mini-Circuits. The series is characterized by its small size and reliable performance in RF applications. These filters are commonly used to suppress unwanted high-frequency signals while passing lower frequencies. The LFCW-5500+ specifically targets applications requiring cutoff characteristics around 5.5 GHz.
