SLP-25+

Overview

The SLP-25+ is a lumped LC low-pass filter from Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of DC to 25 MHz and features a characteristic impedance of 50 ohms. The component utilizes SMA connectors for interface and is housed in the FF99 case style with an ENV105 environmental rating. It supports a maximum RF power input of 0.5W and exhibits a typical attenuation rate of 1.35, defined as the ratio between 20dB and 3dB bandwidths.

Feature Summary

• Lumped LC architecture providing effective low-pass filtering characteristics
• Rugged shielded construction ensuring reliable performance
• SMA connector interface for standard integration

Applications

• Signal conditioning in RF systems
• Frequency filtering in communication equipment
• Shielding against high-frequency interference

Procurement Notes

Verify the specific datasheet version and electrical test conditions prior to procurement. Confirm that the SMA connector type and FF99 package dimensions align with your PCB or assembly requirements. Ensure the 0.5W power handling capacity meets your system's operational limits. Cross-reference the 25 MHz cutoff specification with your design constraints to avoid performance mismatches.

Selection Notes

Select this component when a sharp roll-off is required below 25 MHz with a 50-ohm system impedance. The lumped LC design offers compactness compared to distributed alternatives. Consider the 0.5W power limit for high-power applications. The SMA interface simplifies integration into existing coaxial setups without requiring custom adapters.

Part Context

This part belongs to the Mini-Circuits SLP series of 50-ohm coaxial low-pass filters. The series is characterized by rugged shielded designs and consistent attenuation rates. The SLP-25+ specifically targets applications requiring precise filtering up to 25 MHz, leveraging the manufacturer's established test performance standards for reliability.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified equivalents. Generic replacements may not match the specific 1.35 attenuation rate or 0.5W power handling. Verify that any substitute maintains the SMA interface and 50-ohm impedance to ensure circuit compatibility.
