• Designed for high-current industrial power electronics environments
• Utilizes a robust chassis-mountable housing structure

Power Line Filter Modules Applications

• Frequency converters for motor drives
• Elevator drive systems
• Industrial pump control units
• Traction systems
• Conveyor system power supplies

Power Line Filter Modules Procurement Notes

Verify the specific suffix R140 against official TDK-EPC documentation to confirm terminal type and mechanical dimensions. Ensure the application environment remains within the specified -25°C to +100°C operating range. Confirm that the 90 A rated current aligns with the load requirements. Cross-reference the Wye configuration with the system topology before integration.

Power Line Filter Modules Selection Notes

Select this component when designing three-phase AC input stages for variable frequency drives or similar power conversion equipment. The 90 A rating suits medium-to-high power industrial machinery. Consider the chassis mount form factor for panel integration. Verify compatibility with the specific harmonic mitigation requirements of the target motor drive application.

Power Line Filter Modules Part Context

This component belongs to the B84144A*R140 series of four-line filters manufactured by TDK Electronics AG, formerly EPCOS. These modules are engineered for robust performance in demanding industrial settings. The product line focuses on providing effective noise attenuation for sensitive electronic loads connected to noisy power grids.

Power Line Filter Modules Replacement Considerations

Consult official TDK-EPC substitution guides for direct equivalents. Verify that any alternative maintains the 90 A current rating and three-phase Wye configuration. Mechanical footprint and terminal block compatibility must match the existing chassis design.
