SW3 SG

Overview

The Astrodyne TDI SW3 SG is a single-phase EMC/EMI power line filter module designed for wide-band high-performance noise suppression. It operates at a current rating of 3 A and a voltage rating of 250 VAC at 50/60 Hz. The unit utilizes a single-stage filtering topology to attenuate electromagnetic interference across broad frequency ranges. Mechanical termination is achieved via threaded posts with an 8-32 thread specification, facilitating secure mounting in various industrial and commercial enclosures.

Feature Summary

• Provides wide-band high-performance EMI/EMC filtering capabilities
• Utilizes a single-stage filter topology for efficient noise attenuation
• Features threaded post termination for robust mechanical integration

Applications

• Industrial equipment requiring strict EMI compliance
• Commercial electronic systems needing power line noise reduction
• Medical devices adhering to electromagnetic compatibility standards

Procurement Notes

Verify the specific datasheet version for the SW3 SG model to confirm exact dimensional tolerances and terminal specifications before integration. Ensure that the 8-32 threaded post interface matches the mounting hardware in your design. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select the SW3 SG when a compact single-phase filter is required for applications demanding wide-band noise suppression. The 3 A current rating suits moderate load requirements. Consider the threaded post termination style if panel mounting or rigid connection is preferred over quick-connect terminals. Validate that the single-stage performance meets the specific attenuation needs of the target environment.

Part Context

This component belongs to the SW series of power line filter modules from Astrodyne TDI. These filters are engineered for general-purpose EMI suppression in AC power lines. The series offers various current ratings and termination options to accommodate diverse system architectures and space constraints within electronic assemblies.

Replacement Considerations

Consult official Astrodyne TDI substitution guides for verified equivalents. Generic replacements may not match the wide-band performance characteristics or the specific 8-32 threaded post mechanical interface.
