B84143V0209S231

Power Line Filter Modules Overview

The B84143V0209S231 is a three-phase sine-wave output filter manufactured by EPCOS, part of the TDK Electronics portfolio. Designed for industrial drive systems, this component mitigates high-frequency voltage spikes and common-mode noise generated by pulse-width modulation (PWM) inverters. It protects downstream motors from insulation degradation and bearing currents while ensuring compliance with electromagnetic compatibility standards in demanding electrical environments.

Power Line Filter Modules Feature Summary

• Provides effective attenuation of high-frequency switching noise to protect motor insulation systems
• Designed specifically for sine-wave output applications in three-phase AC drive systems
• Ensures electromagnetic compatibility by reducing conducted emissions above standard limits

Power Line Filter Modules Applications

• Three-phase variable frequency drives (VFDs)
• Industrial motor control systems requiring sine-wave filtering
• Regenerative drive systems

Power Line Filter Modules Procurement Notes

Verify the specific suffix code against official TDK-EPCOS documentation to confirm exact electrical ratings and housing configuration. Ensure the selected variant matches the required input voltage and current specifications for the target application. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Power Line Filter Modules Selection Notes

Select this filter based on the system's rated current and voltage requirements rather than generic family characteristics. Confirm that the filter's attenuation profile aligns with the specific PWM carrier frequency of the inverter. Evaluate physical mounting constraints and thermal management needs relative to the filter's power loss specifications.

Power Line Filter Modules Part Context

This component belongs to the B84143 series of output filters, which are engineered for use between PWM converters and electric motors. The series addresses issues related to dv/dt stress and reflected waves in long cable runs. It represents a specialized solution within TDK's broader portfolio of EMC and power conditioning components.

Power Line Filter Modules Replacement Considerations

Consult official substitution guides for direct equivalents. Verify that any alternative maintains identical phase configuration, current rating, and attenuation performance to ensure system compatibility.
