SXLP-450+

Overview

The SXLP-450+ is a lumped LC low pass filter manufactured by Mini-Circuits, designed for radio frequency signal conditioning. It provides a passband from DC to 450 MHz with a nominal system impedance of 50 ohms. The component utilizes an SMD surface-mount package without leads, specifically an 8-terminal configuration. Key electrical specifications include a cutoff frequency of 465 MHz and a maximum passband insertion loss of 2.5 dB.

Feature Summary

• Lumped LC architecture for effective signal filtering
• Surface-mount construction for automated assembly
• Wide bandwidth operation from DC to 450 MHz

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in RF circuits
• Signal integrity maintenance in microwave assemblies

Procurement Notes

Verify the exact datasheet version directly from Mini-Circuits before procurement. Confirm that the 8-SMD no-lead package dimensions match your PCB footprint requirements. Ensure the 50-ohm impedance specification aligns with your system design. Check for any specific handling instructions regarding moisture sensitivity level 1 during storage and reflow soldering processes.

Selection Notes

Select this component when a compact, surface-mount solution is required for frequencies up to 450 MHz. The lumped LC design offers a balance between size and performance for general-purpose RF filtering. Consider the 2.5 dB insertion loss limit when designing for sensitive signal paths. The 8-terminal SMD package facilitates high-volume manufacturing integration compared to through-hole alternatives.

Part Context

This part belongs to the SXLP series of lumped LC low pass filters from Mini-Circuits. The series covers various frequency ranges, with the SXLP-450+ specifically targeting applications requiring attenuation above 450 MHz. It complements other Mini-Circuits components like amplifiers and mixers in complete RF front-end designs.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-reference part numbers. Verify that any substitute maintains the 50-ohm impedance and similar cutoff characteristics. Ensure the replacement package matches the 8-SMD no-lead form factor for board compatibility.
