SCLF-30+

Overview

The SCLF-30+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications. It operates within a frequency range of DC to 30 MHz with a 50Ω impedance. The component utilizes an 8-SMD, flat lead package configuration. Key electrical specifications include a cutoff frequency of 35 MHz and a passband bandwidth defined at 1dB attenuation.

Feature Summary

• Lumped LC architecture for effective signal conditioning
• Surface-mount design for automated assembly integration
• 50Ω impedance matching for RF system compatibility

Applications

• RF signal path filtering
• IF stage noise reduction
• Base station signal conditioning

Procurement Notes

Verify the specific datasheet revision date against project requirements to ensure parameter consistency. Confirm that the 8-SMD flat lead package dimensions align with the target PCB footprint. Ensure the operating environment remains within the specified thermal limits for reliable long-term performance in RF circuits.

Selection Notes

Select this component when a sharp roll-off is required below 30 MHz with minimal insertion loss in the passband. The 50Ω impedance makes it suitable for standard RF transmission lines. Consider the physical size constraints of the 8-SMD package during layout planning to maintain signal integrity.

Part Context

This part belongs to the SCLF series of surface-mount low-pass filters from Mini-Circuits. The series offers various cutoff frequencies while maintaining consistent packaging and impedance characteristics. It serves as a compact solution for integrating filtering capabilities directly onto circuit boards without requiring through-hole mounting space.

Replacement Considerations

The SCLF-36+ is a documented alternative within the same product family offering a slightly higher frequency range. Verify pinout compatibility and impedance matching before substitution. Other models in the SCLF series may provide different cutoff frequencies but share similar physical footprints.
