3-143-603

Overview

The Schurter 3-143-603 is a single-stage AC power line filter from the FMAB NEO series. It features a rated current of 16 A and operates at 250 VAC with a frequency of 50/60 Hz. Designed for chassis mounting, it utilizes quick connect terminals measuring 6.3 x 0.8 mm. The unit provides standard EMC filtering performance suitable for general industrial applications.

Feature Summary

• Single-stage electromagnetic compatibility filtering
• Chassis mount construction for secure installation
• Quick connect terminal interface for simplified wiring

Applications

• Industrial machinery control panels
• Power supply input stages
• Electronic equipment requiring EMI suppression

Procurement Notes

Verify that the required current rating of 16 A aligns with system demands. Confirm chassis mounting dimensions fit the enclosure design. Ensure quick connect terminals match existing harness specifications. Check compliance requirements against local standards before procurement.

Selection Notes

Select this model when a single-stage filter suffices for noise reduction needs. Compare leakage current limits if sensitive to ground currents. Evaluate thermal derating curves for high ambient temperatures. Consider alternative terminal types if quick connects are unavailable in the assembly process.

Part Context

This component belongs to the FMAB NEO series, which offers compact EMC solutions. The series includes various current ratings and voltage options. It serves as a fundamental building block for power integrity in AC-powered devices.

Replacement Considerations

Check datasheets for equivalent single-stage filters with matching 16 A ratings. Verify terminal pitch compatibility for direct substitution. Ensure voltage ratings meet or exceed 250 VAC requirements.
