SXLP-3+

Overview

The SXLP-3+ is a lumped LC low-pass filter designed for radio frequency applications. It provides a passband from DC to 3 MHz with a cutoff frequency of 3.5 MHz. The component features a typical insertion loss of 1.5 dB and maintains a typical VSWR of 1.2:1. It operates within a 50 Ohm system impedance. The device is housed in an 8-SMD, no lead package, utilizing miniature high Q capacitors and wire-welded inductors to ensure high reliability and repeatable performance across production lots.

Feature Summary

• Utilizes miniature high Q capacitors and wire-welded inductors for high reliability
• Provides fast roll-off characteristics beyond the passband
• Ensures repeatable performance across production lots

Applications

• Low frequency signal filtering
• DC to 3 MHz bandpass applications
• RF circuit protection

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to confirm specifications. Ensure the required package type matches the 8-SMD, no lead configuration. Confirm that the 50 Ohm impedance and 3 MHz cutoff align with the specific design requirements before procurement.

Selection Notes

Select this component when a sharp cutoff near 3.5 MHz is required for low-frequency signals. The 50 Ohm impedance rating suits standard RF systems. Consider the SMD package size for PCB layout constraints. Verify thermal and power handling limits against the specific application load.

Part Context

This component belongs to the SXLP series of lumped LC low-pass filters from Mini-Circuits. The series offers various cutoff frequencies tailored for different low-frequency applications. The SXLP-3+ specifically targets the DC to 3 MHz range, distinguishing it from higher frequency variants like the SXLP-400+.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes with similar cutoff frequencies and impedance ratings. Verify pin compatibility and package dimensions for any alternative components.
