SLP-90+

Overview

The SLP-90+ is a lumped element LC low-pass filter manufactured by Mini-Circuits. It operates from DC to 81 MHz with a nominal system impedance of 50Ω. The component utilizes an SMA connector interface and is housed in the FF99 case style. Typical performance data indicates an insertion loss of 0.05 dB at 1.00 MHz and a group delay of 9.330 nsec at the same frequency.

Feature Summary

• Lumped LC architecture for compact filtering
• SMA coaxial connector interface
• FF99 surface-mount case style

Applications

• RF signal conditioning
• IF stage filtering
• Microwave component integration

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the FF99 package style matches your assembly requirements. Cross-reference electrical parameters with the latest datasheet revision to avoid discrepancies in frequency response or impedance ratings.

Selection Notes

Select this component when a low-pass response up to 81 MHz is required in a 50Ω environment. The lumped LC design offers a specific trade-off between size and performance compared to distributed line filters. Ensure the operating frequency range aligns with the specified cutoff characteristics before integration into the circuit design.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The SLP-90+ belongs to their series of coaxial low-pass filters designed for general-purpose applications. This product line supports various frequency ranges and impedance configurations for diverse electronic systems.

Replacement Considerations

SXLP-90+ is a documented variant within the Mini-Circuits lineup. Verify if the extended frequency range or specific mechanical differences of the SXLP-90+ are necessary for your application before substituting.
