SXLP-40+

Overview

The SXLP-40+ is a lumped LC low-pass RF filter manufactured by Mini-Circuits, designed for operation from DC to 40 MHz. It features a 50 Ohm impedance and an 8-SMD, no-lead package. The component supports a maximum RF power input of 0.5 W and maintains a VSWR of 1.3:1. It provides 20 dB rejection at frequencies between 54-80 MHz. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Lumped LC architecture for compact surface-mount integration
• Low voltage standing wave ratio (VSWR) for efficient signal transmission
• High rejection characteristics in the stopband region

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter outputs
• Interference reduction in test and measurement equipment

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update pin configurations or electrical 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 -40°C to 85°C range to maintain performance integrity. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a sharp cutoff near 40 MHz is required with minimal insertion loss in the passband. The lumped LC design offers a smaller form factor compared to distributed line filters. Consider the 0.5 W power handling limit when designing for high-power applications. The 50 Ohm impedance matches standard RF system requirements without additional matching networks.

Part Context

This part belongs to Mini-Circuits' SXLP series of surface-mount low-pass filters. The series utilizes lumped LC technology to achieve compact sizes while maintaining RF performance. Similar parts in the lineup include variants with different cutoff frequencies, such as the SXLP-10.7+, allowing designers to tailor frequency response characteristics to specific application needs.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other Mini-Circuits SXLP models with similar cutoff frequencies for potential compatibility. Verify that any alternative component matches the 8-SMD package dimensions and pinout configuration to ensure mechanical fit.
