3-137-012

Overview

The SCHURTER Inc. part number 3-137-012 is a single-phase EMC/EMI line filter module designed for power line noise suppression. It features a current rating of 6 A and operates at voltage ratings of 125 V and 250 V within the 50 to 60 Hz frequency range. The component utilizes a single-stage filtering architecture and employs quick-connect terminals for circuit integration. This filter is engineered to meet electromagnetic compatibility standards by attenuating conducted interference on AC power lines.

Feature Summary

• Provides single-stage attenuation of electromagnetic interference for AC power applications
• Utilizes quick-connect terminal configuration for efficient PCB or wire harness mounting
• Engineered for operation across standard 50 Hz and 60 Hz power line frequencies

Applications

• AC power input stages in consumer electronics requiring EMI suppression
• Industrial control systems needing conducted noise reduction on power lines
• Medical equipment power supplies adhering to strict EMC compliance requirements

Procurement Notes

Verify the specific datasheet version for the 3-137-012 to confirm exact leakage current and insertion loss specifications required for your system design. Ensure that the quick-connect terminal dimensions match your assembly tooling and wiring constraints. Cross-reference the voltage rating against your local grid standards to guarantee safe operational margins under all expected load conditions.

Selection Notes

Select this component when a compact, single-stage solution is sufficient for moderate noise attenuation needs. The 6 A rating suits low-to-medium power devices. Consider alternative models if higher current capacity or multi-stage filtering performance is necessary. Verify that the physical footprint and terminal type align with the available space and manufacturing processes in the target product design.

Part Context

This component belongs to Schurter's family of power line filter modules, which are designed to integrate directly into AC power entry circuits. These modules typically combine common-mode and differential-mode filtering elements in a single housing. They serve as critical interfaces between the external power source and internal sensitive electronics, ensuring regulatory compliance for electromagnetic emissions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must consult official manufacturer channels for direct equivalents or cross-reference based on identical electrical parameters such as 6 A rating, 250 V rating, and single-stage topology.
