LFCN-2000+

Overview

The LFCN-2000+ is an LTCC low-pass filter designed for RF and IF applications, offering a cutoff frequency of 2000 MHz. It operates within a 50Ω system and supports DC pass-through from input to output. The component utilizes a compact 4-SMD (No Lead) package with dimensions of 3.20mm x 1.60mm. This surface-mount device is engineered for high performance in microwave circuits, providing effective signal filtering while maintaining a small form factor suitable for modern electronic assemblies.

Feature Summary

• Utilizes LTCC technology for robust construction and miniaturization
• Provides DC pass-through capability between input and output ports
• Designed for 50Ω impedance systems in RF and IF environments

Applications

• RF and IF signal conditioning circuits
• Microwave component integration
• Frequency filtering in communication systems

Procurement Notes

Verify the specific part number suffix when procurement is required. The standard LFCN-2000+ model provides DC pass-through functionality. If DC isolation to ground is necessary for the application, the variant with the 'D' suffix (LFCN-2000D+) must be selected instead, as it offers greater than 100 MOhm isolation to ground. Confirm package type and electrical requirements against official datasheets before ordering.

Selection Notes

Select this component for applications requiring a 2000 MHz cutoff in a 50Ω environment. Ensure the design accommodates the 4-SMD No Lead package dimensions of 3.20mm by 1.60mm. Consider the LFCN-2000D+ variant if circuit topology requires DC isolation rather than DC pass-through. Validate thermal and mechanical constraints associated with surface-mount installation on the target PCB.

Part Context

Mini-Circuits manufactures a broad range of RF, IF, and microwave components spanning from DC to 86 GHz. The LFCN-2000+ belongs to their ceramic filter portfolio, specifically utilizing Low-Temperature Co-fired Ceramic (LTCC) technology. This family of products emphasizes high performance and reliability for demanding electronic applications.

Replacement Considerations

For designs requiring DC isolation to ground instead of DC pass-through, the LFCN-2000D+ is the confirmed substitute within the same product line.
