SCLF-45+

Overview

The SCLF-45+ is a surface-mount low-pass RF filter manufactured by Mini-Circuits. It features an 8-SMD, flat lead package with dimensions of 19.05mm x 9.65mm x 7.11mm. The component operates at a 50Ω impedance and provides a cutoff frequency of 55MHz. It is designed for applications requiring a 1dB bandwidth up to 45MHz. The device complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Surface mount construction for automated assembly
• Low insertion loss characteristics within the passband
• Compact footprint suitable for space-constrained designs

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Interference filtering in receiver front-ends

Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as tape and reel or cut tape, against the manufacturer's current catalog. Confirm that the 8-SMD flat lead package dimensions align with your PCB footprint design rules before finalizing the purchase order.

Selection Notes

Select this component when a sharp cutoff near 55MHz is required for 50Ω systems. Ensure the operating environment remains within the specified temperature range. Verify that the physical size fits the available board space and that the soldering profile supports the flat lead termination style.

Part Context

This part belongs to Mini-Circuits' SCLF series of surface mount low-pass filters. These components are engineered for high performance in compact form factors. The series offers various cutoff frequencies to suit different RF application requirements while maintaining consistent electrical characteristics across the product line.

Replacement Considerations

Check for direct substitutes with identical cutoff frequencies and package types. Verify compatibility with existing PCB footprints and impedance matching networks before swapping components.
