SCLF-4.7+

Overview

The SCLF-4.7+ is a surface mount lumped LC low pass filter manufactured by Mini-Circuits. It provides signal conditioning with a cutoff frequency of 4.7 MHz and operates from DC to 865 MHz. The component features a 50 Ohm impedance and utilizes an 8-SMD, flat leads package configuration. Designed for RF applications, it offers reliable performance within the specified frequency range while maintaining standard impedance matching for integration into electronic circuits.

Feature Summary

• Surface mount construction for automated assembly
• Lumped LC topology for effective filtering
• Standard 50 Ohm system impedance compatibility

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Interference mitigation in receiver front ends

Procurement Notes

Verify the specific revision code on the datasheet before procurement, as Mini-Circuits may update specifications over time. Confirm that the 8-SMD flat lead package dimensions align with your PCB footprint requirements. Ensure the operating environment remains within the thermal limits defined in the official specification sheet to maintain long-term reliability and electrical performance stability.

Selection Notes

Select this component when a sharp cutoff at 4.7 MHz is required for low-frequency RF applications. The 50 Ohm impedance makes it suitable for standard transmission line interfaces. Consider the physical size of the 8-SMD package during layout planning. This filter is appropriate for designs needing attenuation above 4.7 MHz up to higher frequencies without requiring complex discrete component networks.

Part Context

This part belongs to the SCLF series of surface mount low pass filters from Mini-Circuits. The series offers various cutoff frequencies tailored for different RF bandwidths. These components are designed to replace larger through-hole filters in modern compact electronics. The SCLF-4.7+ specifically targets applications requiring precise low-frequency filtering with minimal insertion loss in the passband.

Replacement Considerations

Direct substitutes include other SCLF series variants with similar cutoff frequencies if available. Verify pinout compatibility for the 8-SMD flat lead package when considering alternatives. Check impedance ratings to ensure 50 Ohm matching is maintained in the new component.
