SCLF-36+

Overview

The SCLF-36+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It provides a cutoff frequency of 36 MHz with a 1 dB bandwidth specification. The component operates at a standard impedance of 50 Ohms and covers a frequency range from DC to 36 MHz. It utilizes a surface-mount device (SMD/SMT) termination style housed in a compact package measuring 19.05 mm x 9.65 mm x 7.11 mm. This configuration supports efficient integration into printed circuit boards for signal conditioning tasks requiring precise low-frequency filtering.

Feature Summary

• Utilizes lumped LC topology with miniature high-Q capacitors and wire-welded inductors for stable performance
• Designed for surface-mount assembly to facilitate automated PCB manufacturing processes
• Provides consistent 50 Ohm impedance matching across the operational frequency spectrum

Applications

• RF signal conditioning in communication systems
• Interference suppression in electronic circuits
• Signal filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet version and parameter tolerances directly with Mini-Circuits or authorized distributors before procurement. Confirm that the physical dimensions and pinout align with your PCB footprint requirements. Ensure the operating environment matches the component's specified electrical characteristics. Cross-reference the part number suffix to confirm the exact packaging format required for your production line.

Selection Notes

Select this component when a sharp cutoff at 36 MHz is required within a 50 Ohm system. The lumped LC design offers a compact form factor suitable for space-constrained layouts. Consider the SMD package type for compatibility with standard surface-mount assembly techniques. Evaluate the insertion loss and stopband attenuation specifications against your specific signal integrity requirements to ensure adequate performance.

Part Context

The SCLF series represents Mini-Circuits' lineup of lumped element filters, offering cost-effective solutions for lower frequency RF applications. These components bridge the gap between discrete LC networks and more complex distributed filters. The SCLF-36+ specifically targets applications needing reliable low-pass filtering below 100 MHz, leveraging established Mini-Circuits manufacturing expertise in passive RF components.

Replacement Considerations

Consult Mini-Circuits documentation for direct cross-references. Alternative models may include other SCLF variants with different cutoff frequencies or SLP series connectorized versions if board space permits. Verify impedance and frequency response compatibility before substituting.
