SF3C

Overview

The Astrodyne TDI SF3C is a single-phase, two-stage EMC/EMI power line filter from the RP480 series. It features a terminal block connection style and is rated for 3 A current at 250 VAC. Designed for operation at 50 Hz or 60 Hz, this component provides high-performance switch-mode filtering capabilities.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Terminal block termination for secure electrical connections
• High-performance design optimized for switch-mode applications

Applications

• Single-phase power line conditioning
• EMC/EMI noise reduction in electronic equipment
• Switch-mode power supply input filtering

Procurement Notes

Verify the specific datasheet version to confirm compliance certifications such as UL, CSA, or EN standards. Ensure the terminal block configuration matches your system's wiring requirements. Confirm RoHS status and lead times with authorized distributors, as availability may vary by region.

Selection Notes

Select the SF3C when a single-phase, two-stage solution is required for 3 A circuits. Verify that the terminal block interface suits your assembly process compared to quick-connect alternatives. Ensure the 250 VAC rating aligns with your system's voltage specifications.

Part Context

This component belongs to the RP480 series of power line filters manufactured by Astrodyne TDI. The series includes various models tailored for different current ratings and installation styles, providing standardized EMC solutions for industrial and commercial power systems.

Replacement Considerations

Check the SF3S model within the same series for potential compatibility if pinout or mounting differences exist. Verify that any substitute maintains the two-stage topology and terminal block interface to ensure seamless integration without redesigning the enclosure.
