LFCN-5850D+

Overview

The LFCN-5850D+ is a surface-mount low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates with a cutoff frequency of 6.54 GHz and supports frequencies from DC to 5.85 GHz. The component features a 50 Ohm impedance and utilizes a 4-SMD, no-lead package for board mounting. It is RoHS compliant and suitable for environments ranging from -55°C to +100°C.

Feature Summary

• Surface mount ceramic construction for compact integration
• Low-pass filtering capability up to 6.54 GHz cutoff
• RoHS compliant design for environmental standards

Applications

• RF signal conditioning circuits
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance when ordering. Confirm the package type matches the PCB footprint requirements. Ensure the operating temperature range aligns with the system environment. Check for any specific handling instructions regarding the surface-mount ceramic construction during assembly.

Selection Notes

Select this component for high-frequency applications requiring a sharp cutoff near 6.54 GHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the small 4-SMD footprint for space-constrained designs. Verify that the insertion loss specifications meet the system budget requirements.

Part Context

This part belongs to the LFCN series of low-pass filters from Mini-Circuits. The series offers various cutoff frequencies for different RF applications. The LFCN-5850D+ specifically targets higher frequency ranges compared to lower MHz-rated models in the same family.

Replacement Considerations

Check for direct substitutes within the LFCN series with similar cutoff frequencies. Verify pinout compatibility if replacing with other surface-mount filters. Ensure impedance matching remains at 50 Ohms for seamless integration.
