3-137-005

Overview

The SCHURTER 3-137-005 is a single-phase AC power line filter designed for electromagnetic compatibility (EMC) applications. It operates at a rated voltage of 250VAC and supports a continuous current of 10A within the 50-60Hz frequency range. The unit features a single-stage filtering architecture integrated with a protective earth (PE) choke to suppress conducted interference. It utilizes quick-connect terminals for circuit integration and is housed in a compact form factor suitable for panel or chassis mounting in electronic equipment requiring noise reduction.

Feature Summary

• Integrates a PE choke for enhanced common-mode noise suppression
• Single-stage EMC/EMI filtering architecture
• Quick-connect terminal interface for simplified assembly

Applications

• Industrial control systems
• Medical equipment power supplies
• Information technology hardware

Procurement Notes

Verify the specific datasheet version for the 3-137-005 to confirm exact attenuation curves and physical dimensions, as manufacturer documentation may vary by revision. Ensure the application environment does not exceed the 250VAC rating or 10A current limit. Confirm that the quick-connect terminal type matches the mating connector specifications on the target PCB or wiring harness to ensure reliable electrical contact.

Selection Notes

Select this component when a single-phase solution is required for low-to-medium current applications up to 10A. The integrated PE choke design simplifies bill-of-materials compared to discrete components. Verify that the housing material and thermal characteristics are compatible with the internal temperature rise expected under full load conditions in the final enclosure.

Part Context

This part belongs to the FMAB NEO series of power line filters from Schurter. The series focuses on providing effective EMI suppression for sensitive electronics while maintaining a small footprint. The 3-137-005 specifically addresses standard mains frequency interference, distinguishing it from high-frequency DC filters or three-phase industrial units.
