3-137-019

Overview

The SCHURTER Inc. 3-137-019 is a single-phase EMC/EMI line filter module designed for power line noise suppression. It features a current rating of 3 A and operates at voltages up to 250 VAC within the 50–60 Hz frequency range. The unit utilizes a quick-connect terminal interface for circuit integration. As a first-stage filter, it provides essential electromagnetic interference mitigation for sensitive electronic equipment requiring clean power supply inputs.

Feature Summary

• Single-stage electromagnetic interference (EMI) and radio frequency interference (RFI) filtering
• Quick-connect terminal interface for simplified circuit board mounting
• Designed for single-phase AC power line applications

Applications

• Power supply input stages for consumer electronics
• Electromagnetic compatibility (EMC) pre-filtering in industrial control systems
• Noise suppression for sensitive medical or laboratory instrumentation

Procurement Notes

Verify that the required current rating of 3 A and voltage specification of 250 VAC align with your system design parameters. Confirm that the quick-connect terminal type matches your PCB footprint or wiring harness requirements. Ensure the component meets the specific EMC standards applicable to your target market and end-product certification needs.

Selection Notes

Select this component when a compact, single-stage solution is sufficient for EMI reduction in low-current applications. Consider the physical dimensions and terminal style against available board space. Evaluate if the 3 A rating provides adequate margin for peak load currents without exceeding thermal limits during continuous operation.
