SCLF-5+

Overview

The SCLF-5+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications. It operates with a cutoff frequency of 5 MHz and maintains a characteristic impedance of 50 ohms. The component utilizes an inductor-capacitor topology to attenuate high-frequency signals while passing DC and low-frequency content. It is housed in the YY161 case style, suitable for compact PCB layouts. This filter supports environments requiring reliable signal conditioning within the specified bandwidth.

Feature Summary

• Lumped LC architecture for effective low-pass filtering
• Surface-mount design compatible with automated assembly
• 50-ohm impedance matching for standard RF systems

Applications

• Signal conditioning in communication systems
• Noise suppression in electronic circuits
• Frequency selection in test and measurement equipment

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct packaging and variant selection. Confirm that the YY161 package dimensions align with your PCB footprint requirements. Check RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when a sharp cutoff at 5 MHz is required in a 50-ohm system. The lumped LC design offers a compact solution compared to distributed line filters. Consider the thermal performance and power handling capabilities relative to your signal levels. Evaluate the insertion loss and stopband attenuation characteristics against your system's noise floor requirements.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to high frequencies.
