Overview
The LFCN-225D+ is an LTCC low-pass filter designed for DC to 225 MHz operation with a 50Ω impedance. It utilizes seven-section technology in an FV1206 SMD package. The component offers excellent power handling of 8.5W and temperature stability. It is available in tape and reel format.
Feature Summary
- LTCC construction for temperature stability
- High power handling capability
- Seven-section design
- Protected by U.S. Patent
Applications
- RF signal processing
- IF filtering
- Microwave applications
Procurement Notes
Verify the exact part number suffix, as 'D+' indicates specific packaging or revision. Confirm the case style matches the required footprint. Ensure the operating frequency range aligns with system requirements. Check datasheet for precise insertion loss and rejection specs at critical frequencies.
Selection Notes
Select this component when a compact, high-power low-pass filter is needed below 225 MHz. The LTCC technology ensures reliability in varying thermal conditions. Consider the FV1206 size for space-constrained PCB layouts. Verify compatibility with 50Ω system impedance.
Part Context
Mini-Circuits specializes in RF, IF, and microwave components from DC to 86GHz. The LFCN series represents their LTCC filter offerings. This model is part of a broader portfolio including amplifiers, mixers, and couplers. Mini-Circuits provides both packaged and bare die options.
Replacement Considerations
LFCN-225+ is the standard version without the D+ suffix. Verify if the packaging difference affects integration. No other direct substitutes are confirmed in public documentation.
