LFCV-45+

Overview

The LFCV-45+ is a low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications in a compact 1210 (3225 Metric) package with four pads. It operates over a frequency range from DC to 45 MHz with a characteristic impedance of 50 Ohms. The component exhibits a typical insertion loss of 1.2 dB and provides high rejection performance, specified at 50 dB typical. It is constructed using LTCC technology with a seven-section design.

Feature Summary

• Utilizes LTCC technology with a seven-section architecture
• Provides high signal rejection capabilities
• Supports high power handling capacity
• Features a compact surface-mount footprint

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter chains
• Interference filtering in receiver front-ends

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation to confirm electrical parameters such as insertion loss and rejection levels. Ensure the selected component matches the required 50 Ohm impedance and 1210 package dimensions for proper PCB integration. Cross-reference official specifications to validate power handling ratings before implementation.

Selection Notes

Select this component when a low-pass filter with a cutoff near 45 MHz is required in a space-constrained design. Consider the LTCC construction for stability and the 1210 package size for compatibility with standard surface-mount assembly processes. Evaluate the 8W power handling against system requirements to ensure adequate margin for operational signals.

Part Context

This part belongs to the Mini-Circuits LFCV series, which extends the lower frequency cutoff range of the existing LFCN series. The series utilizes Low Temperature Co-fired Ceramic (LTCC) technology to provide robust performance in a small form factor suitable for modern electronic assemblies.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Do not assume functional equivalence with other low-pass filters without confirming matching impedance, cutoff frequency, and package constraints.
