SW20 F

Overview

The Astrodyne TDI SW20 F is a single-phase EMC/EMI line filter rated for 20 A current and 250 V AC operation at 50/60 Hz frequencies. Designed as a single-stage solution, it utilizes a threaded post mounting configuration with an 8-32 thread specification to secure the unit within electrical assemblies. This component functions as a power line filter module intended to suppress electromagnetic interference in general-purpose applications requiring robust noise attenuation.

Feature Summary

• Single-phase electromagnetic interference suppression
• Threaded post mechanical mounting interface
• Single-stage filtering architecture

Applications

• General-purpose electromagnetic interference suppression systems
• Single-phase power line filtering assemblies
• Chassis-mounted electronic equipment noise reduction

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly from the manufacturer or authorized distributor before procurement. Confirm that the 8-32 threaded post mounting requirement aligns with the target chassis design. Ensure the 20 A continuous current rating and 250 V AC voltage specifications meet the operational requirements of the intended circuit application without exceeding limits.

Selection Notes

Select this component when a single-phase EMI filter with a 20 A capacity and 250 V AC rating is required. The choice depends on the availability of a threaded post mounting option compatible with the 8-32 standard. Consider the single-stage filtering performance sufficient for the specific noise environment. Verify that the physical dimensions and thermal characteristics support the installation constraints of the final assembly.

Part Context

The SW20 F belongs to the SW series of wide-band high-performance EMI filters manufactured by Astrodyne TDI. This series provides solutions for various electromagnetic interference challenges across different current ratings and mounting styles. The SW20 F specifically addresses single-phase applications requiring substantial current handling capabilities while maintaining effective noise suppression through its dedicated internal filtering components.

Replacement Considerations

Public sources indicate the SW20 F may be discontinued. Check for alternative part numbers within the Astrodyne TDI SW series or comparable single-phase EMI filters with matching 20 A ratings and threaded post mounting interfaces. Verify electrical parameters and mechanical fit before substitution.
