3-137-025

Overview

The SCHURTER 3-137-025 is a single-phase AC power line filter from the FMAB NEO series, rated for 16 A at 250 VAC. It features an integrated PE choke and utilizes quick connect terminals for circuit board mounting. The unit operates within a temperature range of -40°C to +100°C with a leakage current of 1.57 mA. Designed for DIN rail installation styles in application contexts, it functions at 50/60 Hz frequencies.

Feature Summary

• Integrates a protective earth (PE) choke for enhanced electromagnetic interference suppression
• Utilizes quick connect termination style for efficient printed circuit board assembly
• Constructed for high thermal stability operating up to +100°C

Applications

• Single-phase AC power line filtering
• Electromagnetic compatibility (EMC) mitigation in electronic equipment
• Industrial control system power inputs

Procurement Notes

Verify the specific datasheet version for the 3-137-025 to confirm exact attenuation curves and terminal pitch dimensions prior to integration. Ensure that the 16A continuous current rating aligns with the maximum load requirements of the target circuit design to prevent thermal overload during operation.

Selection Notes

Select this component when a compact, single-stage solution is required for 250VAC environments. The integrated PE choke simplifies bill of materials by combining filtering and grounding functions. Confirm that the quick connect footprint matches the available PCB layout constraints and that the 1.57 mA leakage current meets safety isolation standards for the end product.

Part Context

This component belongs to the FMAB NEO series of power line filters manufactured by SCHURTER Inc. The series is engineered for general industrial applications requiring reliable noise suppression. The 3-137-025 variant specifically addresses single-phase needs with standardized quick-connect interfaces common in modern electronic assemblies.

Replacement Considerations

Cross-reference with other FMAB NEO models for different current ratings or attenuation characteristics. Verify mechanical footprint compatibility before substituting with generic single-phase filters to ensure proper terminal alignment and mounting stability.
