3-143-620

Overview

The SCHURTER Inc. part number 3-143-620 is a single-phase EMC/EMI power line filter module designed for chassis mounting. It features quick-connect terminals and supports an AC voltage rating of 250V at 50/60Hz with an 8A current capacity. The unit utilizes a single-stage filtering architecture to suppress electromagnetic interference in electrical circuits.

Feature Summary

• Single-stage EMI suppression for noise reduction
• Quick-connect terminal interface for rapid assembly
• Chassis mount construction for stable installation

Applications

• Industrial equipment power input stages
• Medical device power supply units
• Consumer electronics EMC compliance

Procurement Notes

Verify the specific datasheet revision to confirm terminal spacing and mounting hole dimensions prior to PCB or panel design finalization. Ensure the operating environment temperature remains within the component's specified range to maintain performance integrity and safety certification validity.

Selection Notes

Select this model when a compact, single-phase solution is required for 250VAC systems drawing up to 8A. The quick-connect style suits applications prioritizing assembly speed over soldered connections. Confirm that the single-stage attenuation meets the target EMC standards for the end product.

Part Context

This component belongs to the FMAB NEO series of power line filters from Schurter. The series focuses on providing efficient noise suppression in a small footprint suitable for modern electronic devices requiring robust EMI protection without excessive size constraints.

Replacement Considerations

Cross-reference with other FMAB series variants for identical electrical ratings but different terminal styles or mounting configurations if mechanical fitment requires adjustment.
