SLP-50+

Overview

The SLP-50+ is a coaxial low-pass RF filter manufactured by Mini-Circuits, designed for signal integrity in radio frequency applications. It operates with a cutoff frequency of 48 MHz and maintains a standard 50 Ω impedance across its DC to 48 MHz passband. The component utilizes lumped LC technology housed in a shielded stainless steel case, ensuring robust performance against external interference. Key electrical characteristics include a maximum input power of 0.5 W and a typical VSWR of 1.7:1. It provides significant rejection, achieving 20 dB attenuation at frequencies between 70 and 90 MHz. The device features SMA connectors for reliable in-line integration.

Feature Summary

• Shielded stainless steel construction for environmental protection and signal isolation
• Lumped LC design optimized for wideband 50 Ω operation
• SMA connector interface for standardized in-line module integration

Applications

• RF transmitter and receiver circuit filtering
• Harmonic suppression in wireless communication systems
• Signal conditioning in industrial measurement equipment

Procurement Notes

Verify the specific ordering suffix when sourcing the SLP-50+. Confirm that the required connector type matches the SMA specification documented in the official datasheet. Ensure the application environment remains within the stated 0.5 W maximum input power limit to maintain component reliability and prevent damage. Cross-reference the part number with the manufacturer's current documentation to confirm availability and exact technical specifications.

Selection Notes

Select the SLP-50+ for applications requiring effective low-frequency signal passage while attenuating higher frequencies above 48 MHz. Its compact coaxial form factor suits space-constrained designs. The 50 Ω impedance ensures compatibility with standard RF test equipment and transmission lines. Consider the 0.5 W power handling capability when designing circuits with moderate signal levels. The shielded case makes it suitable for environments where electromagnetic interference mitigation is necessary.
