SXLP-23+

Overview

The SXLP-23+ is a lumped LC low-pass RF filter manufactured by Mini-Circuits. It operates from DC to 23 MHz with a 50Ω impedance. The device features an 8-SMD, no-lead surface-mount package. Key electrical specifications include a 1dB cutoff frequency of 23MHz and a rejection of 20 dB at 31-34 MHz. It supports a maximum power handling of 0.5 W and maintains a VSWR of 1.5:1.

Feature Summary

• Surface-mount SMD construction for automated PCB assembly
• Lumped LC topology providing sharp roll-off characteristics
• Designed for 50Ω system integration

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Noise filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update component specifications over time. Confirm that the 8-SMD no-lead package footprint matches your PCB design constraints. Ensure the operating environment stays within the specified power and voltage limits to maintain performance integrity and device longevity.

Selection Notes

Select this component when a low-pass response up to 23 MHz is required in a compact form factor. The 50Ω impedance aligns with standard RF transmission lines. Consider the 0.5 W power rating for signal levels; higher power applications require different thermal management or component choices.

Part Context

This part belongs to the SXLP series of lumped LC filters from Mini-Circuits, which covers frequencies up to 400 MHz. These components are designed for general-purpose RF applications requiring reliable low-pass filtering in space-constrained environments.

Replacement Considerations

Direct substitutes should match the 23 MHz cutoff, 50Ω impedance, and 8-SMD package. Verify equivalent rejection specs at 31-34 MHz and power handling capabilities before substitution.
