LFCV-52+

Overview

The LFCV-52+ is a low-pass ceramic filter manufactured by Mini-Circuits, designed for surface-mount applications. It features a 4-SMD module package with dimensions of 3.00mm x 3.00mm and a maximum height of 0.99mm. The component operates at a characteristic impedance of 50 Ohms and provides a cutoff frequency of 93MHz. Key electrical specifications include an insertion loss of 1.2dB. The device utilizes LTCC technology with a seven-section design to extend the lower frequency cutoff range.

Feature Summary

• LTCC-based seven-section design for enhanced filtering performance
• Compact 4-SMD surface-mount package suitable for space-constrained layouts
• High power handling capability supporting up to 8W
• High rejection characteristics providing typical attenuation of 50 dB

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter output stages
• Interstage filtering in multi-stage amplifier chains
• Base station RF front-end modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging configuration, such as tape and reel or cut tape options. Confirm that the 93MHz cutoff specification aligns with your system requirements, as this parameter defines the filter's operational boundary. Ensure compatibility with standard SMD reflow soldering profiles for the 4-SMD module package to maintain electrical integrity and mechanical stability during assembly processes.

Selection Notes

Select the LFCV-52+ when a low-pass filter with a 50 Ohm impedance is required for frequencies up to 93MHz. Its compact 3.00mm x 3.00mm footprint makes it suitable for dense PCB layouts where space is limited. The high power handling rating of 8W allows use in higher power applications compared to smaller passive components. Consider its LTCC construction for reliable performance in environments requiring stable thermal characteristics and consistent electrical behavior over temperature variations.

Part Context

This component belongs to Mini-Circuits' LFCV series of low-pass filters, which utilize Low Temperature Co-fired Ceramic (LTCC) technology. The series is engineered to provide sharp cutoff characteristics and high rejection levels. The LFCV-52+ specifically extends the functionality of previous series like the LFCN, offering improved performance at lower frequency ranges while maintaining the small form factor and robust construction typical of Mini-Circuits' ceramic filter products.

Replacement Considerations

Direct substitutes may include other Mini-Circuits LTCC low-pass filters within the LFCV or LFCN series that match the 50 Ohm impedance and similar cutoff frequencies. Verify pinout compatibility and physical dimensions before swapping to ensure fit within existing board footprints. Alternative manufacturers producing 4-SMD ceramic low-pass filters with comparable 93MHz cutoff and 1.2dB insertion loss specifications should be evaluated for equivalent power handling and rejection performance.
