Overview
The Astrodyne TDI SX20A F is a single-phase EMC/EMI power line filter designed for chassis mounting. It features a three-stage filtering architecture utilizing a threaded post termination style (8-32). The component is rated for 250 VAC and supports a continuous current of 20 A at operating frequencies of 50 Hz and 60 Hz. This unit complies with UL, CSA, EN, CE, cURus, and SEMKO safety standards, ensuring suitability for global industrial applications requiring robust electromagnetic interference suppression.
Feature Summary
- Three-stage internal filtering topology for enhanced noise attenuation
- Threaded post termination design for secure mechanical integration
- Comprehensive international safety certifications including UL, CSA, and EN
Applications
- Industrial machinery control panels
- Medical equipment power supplies
- General purpose electronic systems requiring EMI suppression
Procurement Notes
Verify the specific datasheet version to confirm exact dimensional tolerances and terminal specifications. Ensure the application environment matches the rated voltage and current limits. Confirm that the chassis mounting method aligns with the threaded post requirement. Cross-reference certification marks with local regulatory requirements before deployment.
Selection Notes
Select this model when high-current single-phase filtering is required in a compact chassis-mount form factor. The three-stage design offers superior performance compared to single-stage alternatives. Verify that the 8-32 threaded post interface is compatible with existing panel hardware. Consider thermal management requirements based on the expected load current.
Part Context
This component belongs to the SX Series of power line filters from Astrodyne TDI. The series is characterized by modular designs and robust construction for industrial environments. The SX20A F specifically addresses needs for higher current handling within a standardized footprint, distinguishing it from lower-capacity variants in the same product family.
Replacement Considerations
Direct substitutes must match the 20 A rating, 250 VAC specification, and three-stage topology. Verify compatibility with the 8-32 threaded post termination. Check for equivalent safety approvals if deploying in regulated markets. Generic single-stage filters may not provide sufficient attenuation.
