SX3C

Overview

The SX3C is a single-phase EMC/EMI power line filter module from the Astrodyne TDI product portfolio. It is designed for chassis mounting and features a three-stage filtering architecture to ensure effective noise suppression in sensitive electronic environments. The unit operates at a rated voltage of 250 VAC and supports a continuous current rating of 3 A at standard frequencies of 50 Hz and 60 Hz. Termination is achieved via terminal block connections, facilitating integration into industrial control panels and medical equipment power inputs.

Feature Summary

• Three-stage EMI/RFI attenuation architecture for enhanced signal purity
• Chassis mount design with terminal block termination for secure installation
• Optimized for low leakage current performance in safety-critical applications

Applications

• Medical imaging systems requiring strict electromagnetic compatibility
• Industrial automation control panels
• Precision diagnostic equipment power inputs

Procurement Notes

Verify the specific datasheet version and compliance documentation prior to procurement. Confirm that the terminal block configuration matches the existing wiring harness. Ensure the chassis mounting dimensions align with the enclosure design. Validate that the 3 A current rating meets the operational load requirements without derating issues under ambient temperature conditions.

Selection Notes

Select this component when high attenuation across a broad frequency spectrum is required for single-phase AC lines. The three-stage design offers superior performance compared to two-stage alternatives for noisy environments. Ensure the application environment allows for chassis mounting and provides adequate clearance for the terminal block connections during maintenance.

Part Context

This component belongs to the Astrodyne TDI line filter series, which specializes in power conditioning solutions. The SX3C represents a specialized module within their portfolio, focusing on high-performance interference suppression for critical infrastructure. It complements other series by offering a compact yet robust solution for stringent EMC standards.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative three-stage filters from the same manufacturer only if electrical ratings and physical dimensions are identical. Verify compatibility with existing mounting hardware and terminal specifications before considering any cross-brand substitution.
