SCLF-65+

Overview

The SCLF-65+ is a coaxial low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications in the 1206 (3216 Metric) package. It operates from DC to 65 MHz with a cutoff frequency of 71 MHz and maintains a system impedance of 50 Ohms. The component features an insertion loss of 1 dB and utilizes a four-pad SMD/SMT termination style. This filter provides signal conditioning for RF circuits requiring attenuation of frequencies above the specified passband while preserving signal integrity within the operational range.

Feature Summary

• Coaxial construction ensures stable performance and shielding
• Surface-mount design facilitates automated PCB assembly
• Low insertion loss preserves signal strength in the passband

Applications

• RF signal path filtering in communication systems
• Harmonic suppression in transmitter outputs
• Noise reduction in receiver front-ends

Procurement Notes

Verify the specific datasheet version for the SCLF-65+ to confirm mechanical dimensions and soldering profiles. Ensure compatibility with 50 Ohm system impedance requirements. Check for RoHS compliance status if required by your manufacturing standards. Confirm that the 1206 package size fits within your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact, surface-mount low-pass filter is needed for frequencies up to 65 MHz. The 1206 package offers a balance between size and power handling. Consider the 1 dB insertion loss impact on overall system gain. Verify that the 71 MHz cutoff frequency aligns with the desired stopband start point for your specific application requirements.

Part Context

Mini-Circuits produces a wide range of RF and microwave components, including filters, amplifiers, and mixers. The SCLF series represents their line of coaxial low-pass filters designed for high reliability. These components are commonly used in test equipment, wireless infrastructure, and industrial applications where consistent frequency response is critical.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes. Alternative low-pass filters from other manufacturers may require impedance and package re-evaluation. Ensure any replacement matches the 50 Ohm impedance and 1206 footprint to maintain board compatibility.
