SLP-250+

Overview

The SLP-250+ is a coaxial lumped LC low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of DC to 225 MHz with a 50-ohm impedance system. The component utilizes SMA connectors for inline installation and is housed in a bulk package. Typical performance data indicates an insertion loss of 0.10 dB at 50 MHz and 36.65 dB rejection at the same frequency. At 100 MHz, insertion loss is 0.22 dB with 20.91 dB rejection. The device exhibits a VSWR of 1.7:1 and provides group delay characteristics suitable for RF signal processing.

Feature Summary

• Lumped LC architecture for effective low-pass filtering
• SMA connector interface for direct inline integration
• Coaxial module design ensuring stable RF performance

Applications

• RF signal conditioning systems
• Low-pass filtering in communication circuits
• Signal integrity management in test equipment

Procurement Notes

Verify the specific datasheet version when ordering, as electrical specifications may be updated by the manufacturer. Confirm that the SMA connector type matches your system requirements. Ensure the 50-ohm impedance aligns with your circuit design. Check for any recent revisions to the typical performance curves before finalizing integration plans.

Selection Notes

Select this component when a sharp cutoff below 225 MHz is required with minimal insertion loss in the passband. The lumped LC construction offers compact sizing compared to distributed line filters. Consider the SMA interface compatibility and ensure the operating environment does not exceed the specified thermal limits for reliable long-term operation.

Part Context

This part belongs to the SLP series of coaxial low-pass filters from Mini-Circuits. These components are engineered for high-reliability RF applications requiring precise frequency control. The series typically includes various cutoff frequencies to suit different bandwidth needs while maintaining consistent mechanical and electrical standards across the product line.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement maintains the 50-ohm impedance and SMA interface. Ensure the new component meets or exceeds the 225 MHz cutoff requirement and similar rejection characteristics at higher frequencies.
