3-137-006

Overview

The SCHURTER 3-137-006 is a single-phase power line filter designed for AC mains applications. It operates at a voltage of 250 VAC and supports a continuous current rating of 12 A. The unit incorporates a PE choke for enhanced noise suppression within a standard EMC/EMI configuration. Designed for chassis mounting, this filter provides one-stage attenuation suitable for general-purpose electronic equipment requiring reliable power line conditioning.

Feature Summary

• Integrates a PE choke for effective electromagnetic interference suppression
• Provides single-stage filtering for AC power lines
• Engineered for secure chassis mounting installation

Applications

• General-purpose electronic equipment power input stages
• Industrial control systems requiring EMI mitigation
• Medical device power supplies

Procurement Notes

Verify the specific datasheet version to confirm terminal type compatibility with existing PCB or wiring harnesses. Ensure the chassis mounting holes align with the enclosure design specifications. Confirm that the 12 A current rating meets the peak load requirements of the target application without derating issues under expected ambient temperatures.

Selection Notes

Select this component when a single-stage solution with integrated common-mode choke is required for 250 VAC circuits. It is appropriate for applications where space constraints favor a compact chassis-mount form factor over panel-mount alternatives. Evaluate thermal management needs as the unit dissipates heat proportional to the load current.

Part Context

This part belongs to Schurter's FMAB NEO series of power line filters. The series is characterized by high performance in a compact footprint, utilizing advanced magnetic components to achieve significant attenuation in minimal space. It serves as a critical interface between the AC mains supply and sensitive downstream electronics.

FAQ

What is the primary function of the PE choke in this filter?

The PE choke acts as a common-mode inductor to suppress electromagnetic interference (EMI) noise on the power lines, preventing both emission from and susceptibility to external disturbances.

Is this filter suitable for DC applications?

No, the 3-137-006 is specifically rated for 250 VAC operation and is designed for AC power line filtering, not DC circuits.
