LFCN-1000+

Overview

The LFCN-1000+ is a low-pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It operates from DC to 1000 MHz with a characteristic impedance of 50Ω. The component utilizes LTCC technology and is housed in an FV1206 case style. It is supplied in tape and reel packaging.

Feature Summary

• Provides signal filtering within the specified frequency range
• Utilizes LTCC construction for compact integration
• Designed for standard 50Ω system impedance

Applications

• RF front-end filtering
• Microwave circuit design
• Signal integrity management in communication systems

Procurement Notes

Verify the specific suffix requirements for your application. The standard LFCN-1000+ model does not support DC pass-through between input and output. If DC continuity is required, confirm availability of the LFCN-1000D+ variant which offers high isolation to ground. Ensure compatibility with the FV1206 footprint during procurement planning.

Selection Notes

Select this component when a low-pass response up to 1000 MHz is necessary in a small form factor. Consider the LFCN-1000D+ if DC path functionality is essential, as the standard version lacks this feature. Confirm that the LTCC package type meets the thermal and mechanical constraints of the target PCB assembly before finalizing the part number.

Part Context

This component belongs to Mini-Circuits' LTCC low-pass filter series, which covers frequencies from DC to 86 GHz. The LFCN-1000+ specifically addresses needs in the lower microwave spectrum. It is part of a broader portfolio including various impedance and cutoff frequency options for diverse RF system architectures.

Replacement Considerations

The LFCN-1000D+ is a confirmed substitute variant offering DC pass-through capability while maintaining similar electrical characteristics. Verify pinout and footprint compatibility before substitution.
