LFCN-225+

Overview

The LFCN-225+ is a Surface Mount Device (SMD) LTCC low-pass filter manufactured by Mini-Circuits. It features a cutoff frequency of 225 MHz and operates with a 50Ω impedance. The component utilizes ceramic technology and is housed in an FV1206 case style package. This filter provides signal conditioning for RF applications, ensuring effective attenuation of frequencies above the specified cutoff point while maintaining signal integrity within the passband.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact surface mount integration
• Provides low-pass filtering functionality with a defined 225 MHz cutoff frequency
• Designed for 50Ω system impedance compatibility
• Housed in a small form factor FV1206 SMD package

Applications

• RF front-end signal conditioning
• Harmonic suppression in transmission lines
• Interference filtering in communication systems

Procurement Notes

Verify the exact part number suffix when ordering. The standard LFCN-225+ variant typically blocks DC, whereas the LFCN-225D+ version supports DC pass-through with high isolation to ground. Confirm the required electrical configuration matches the specific application needs before procurement to ensure correct component selection.

Selection Notes

Select this component for applications requiring a sharp roll-off below 225 MHz in a minimal footprint. Consider the LFCN-225D+ variant if DC continuity is necessary. Ensure the design accommodates the FV1206 package dimensions and thermal requirements associated with LTCC components in high-frequency circuits.

Part Context

This component belongs to the LFCN series of ceramic filters from Mini-Circuits, which are designed for high-performance RF and microwave applications. The series offers various cutoff frequencies and configurations, providing engineers with standardized solutions for filtering needs across different frequency bands and system impedances.

Replacement Considerations

The LFCN-225D+ serves as a functional substitute if DC pass capability is required. Verify that any alternative replacement maintains the 225 MHz cutoff, 50Ω impedance, and compatible FV1206 package dimensions to ensure seamless integration without PCB redesign.
