SCLF-27+

Overview

The SCLF-27+ is a surface-mount low-pass filter manufactured by Mini-Circuits, designed for radio frequency signal conditioning. It features a cutoff frequency of 27 MHz and operates from DC to 865 MHz. The component maintains a system impedance of 50 Ohms and utilizes an SMD/SMT termination style with flat leads in an 8-SMD package. It is rated for operation within a temperature range of -40°C to +85°C. The device complies with RoHS and REACH standards, ensuring environmental safety for electronic assemblies.

Feature Summary

• Provides effective attenuation of frequencies above the 27 MHz cutoff point
• Designed for surface-mount integration into compact RF circuits
• Maintains 50 Ohm impedance matching for standard transmission lines

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter output stages
• Anti-aliasing filtering in data acquisition front-ends

Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance when sourcing. Confirm the package type matches the 8-SMD flat lead specification required by your PCB footprint. Ensure the operating temperature range meets your environmental requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a sharp cutoff at 27 MHz is required for low-frequency RF applications. Consider the 8-SMD package size for space-constrained designs. Verify that the 50 Ohm impedance aligns with your system's transmission line characteristics. Evaluate the thermal performance against the specified -40°C to +85°C operational limits.

Part Context

This component belongs to the SCLF series of low-pass filters from Mini-Circuits, which are engineered for general-purpose RF signal processing. The series offers various cutoff frequencies to suit different bandwidth requirements. These filters are commonly used in test equipment, instrumentation, and wireless infrastructure where precise frequency control is necessary.

Replacement Considerations

Consult Mini-Circuits documentation for direct equivalents within the SCLF series with similar cutoff frequencies. Verify pin compatibility and impedance matching before substituting with components from other manufacturers.
