SCLF-44+

Overview

The SCLF-44+ is a surface-mount lumped LC low-pass 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 with a 50 Ohm impedance and provides a cutoff frequency of 48.5MHz at the 1dB bandwidth point. Designed for frequencies from DC to 44 MHz in the passband, it supports RoHS3 compliance and has a Moisture Sensitivity Level (MSL) rating of 1.

Feature Summary

• Utilizes lumped LC topology for compact surface-mount integration
• Provides effective signal attenuation above the specified cutoff frequency
• Maintains 50 Ohm system impedance compatibility

Applications

• RF signal conditioning circuits
• Harmonic suppression in RF transmitters
• Noise filtering in communication systems

Procurement Notes

Verify the specific ordering suffix when purchasing, as packaging variations such as tape and reel may exist. Confirm that the required quantity aligns with the manufacturer's standard packaging units. Ensure the component meets the necessary environmental standards, specifically RoHS3 compliance, for your assembly process. Cross-reference the part number with official distributor catalogs to confirm current availability status before finalizing procurement plans.

Selection Notes

Select this component when a low-pass filter with a 48.5MHz cutoff is required for surface-mount applications. The 8-SMD package offers a footprint suitable for dense PCB layouts. Consider the 50 Ohm impedance match for standard RF systems. Evaluate the physical dimensions against available board space constraints. Verify that the lumped LC design meets the specific frequency response requirements of the target application.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86GHz. The SCLF series represents their line of surface-mount low-pass filters designed for signal integrity.
