LFCW-143+

Overview

The LFCW-143+ is a surface-mount LTCC low-pass filter manufactured by Mini-Circuits. It features a cutoff frequency of 16 GHz and operates within a 50 Ohm system impedance. The device utilizes a compact 0603 (1608 Metric) package with four pads for SMT assembly. Key electrical specifications include a typical passband insertion loss of 1.2 dB and a maximum DC to 14 GHz passband range. This component is designed for signal conditioning applications requiring high-frequency filtering in a small form factor.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction.

Applications

• Signal conditioning in RF circuits

Procurement Notes

Verify the specific datasheet version from Mini-Circuits to confirm current electrical tolerances and RoHS compliance status. Ensure the 0603 footprint matches the PCB layout requirements. Confirm that the 16 GHz cutoff specification aligns with the target application's frequency constraints before finalizing procurement.

Selection Notes

Select this component when a 16 GHz low-pass characteristic is required in a minimal 0603 footprint. Consider the 1.2 dB insertion loss impact on system gain. Verify compatibility with standard SMT reflow processes suitable for LTCC materials. Ensure the 50 Ohm impedance matches the surrounding circuit design.

Part Context

This part belongs to Mini-Circuits' LFCW series of ceramic low-pass filters. These components are engineered for high-frequency performance using LTCC technology. The series offers various cutoff frequencies in standardized surface-mount packages, providing reliable signal filtering for RF and microwave applications.

Replacement Considerations

Consult Mini-Circuits documentation for direct cross-references. Verify that any substitute maintains the 16 GHz cutoff, 0603 package dimensions, and 50 Ohm impedance characteristics.
