Overview
The Astrodyne TDI SF20A is a single-phase, two-stage EMI/EMC power line filter module designed for high-performance applications. It features a rated current of 20 A and operates at voltages up to 250 VAC across 50 Hz and 60 Hz frequencies. The unit utilizes threaded post termination with an 8-32 thread specification for secure chassis mounting. This component provides effective electromagnetic interference suppression in demanding electrical environments.
Feature Summary
- Two-stage filtering architecture for enhanced noise attenuation
- Threaded post termination configuration for robust mechanical connection
- High current capacity suitable for switch mode power supplies
Applications
- General purpose industrial equipment
- Switch mode power supply integration
- Electromagnetic compatibility systems
Procurement Notes
Verify the specific datasheet version and compliance certifications prior to procurement. Confirm that the 8-32 threaded post interface matches the mounting hardware requirements of the target enclosure. Ensure the 20 A continuous current rating aligns with the system load profile to prevent thermal overload during operation.
Selection Notes
Select this model when a compact, two-stage solution is required for single-phase AC lines. The SF20A is appropriate for applications needing reliable EMI suppression without complex PCB integration. Consider the chassis mount form factor if space constraints favor modular components over through-hole designs.
Part Context
This component belongs to the SF series of power line filters manufactured by Astrodyne TDI. The series focuses on providing engineered solutions for electromagnetic interference in various industrial and commercial sectors. The SF20A represents a standard offering within this portfolio for general-purpose filtering needs.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Generic cross-references may not match the two-stage topology or termination specifications.
