LFCW-272+

Overview

The LFCW-272+ is an LTCC low-pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It operates from DC to a cutoff frequency of 2690 MHz with a 50 Ohm impedance. The component utilizes a JC0603C surface-mount package (0603 metric). Key electrical characteristics include low passband insertion loss and high stopband rejection, achieved through its strategic internal layout. It supports board mounting and functions within a temperature range suitable for industrial environments.

Feature Summary

• Utilizes LTCC technology for compact surface-mount integration
• Provides effective signal filtering with low passband insertion loss
• Delivers strong stopband rejection via strategic internal construction

Applications

• RF front-end filtering in communication systems
• Signal conditioning in microwave circuits
• Harmonic suppression in transmitter outputs

Procurement Notes

Verify the specific datasheet revision and electrical test data directly from Mini-Circuits before integration. Confirm that the JC0603C footprint matches your PCB design guidelines. Ensure operating conditions remain within the specified thermal limits to maintain performance stability and reliability over the component's lifecycle.

Selection Notes

Select this component when a compact, low-loss low-pass filter is required up to approximately 2.7 GHz. The 0603 package size suits space-constrained designs. Consider the trade-off between insertion loss and physical dimensions compared to larger ceramic or waveguide alternatives for similar frequency ranges.

Part Context

This part belongs to the LFCW series of LTCC ceramic filters from Mini-Circuits. These components are engineered for high performance in RF and IF stages.
