B84143K0250S081

Power Line Filter Modules Overview

The EPCOS B84143K0250S081 is a three-phase power line EMC filter designed for industrial converters and power electronics. It supports a rated current of 250A and operates at AC voltages up to 760V (line-to-line) or 440V (line-to-neutral). The unit withstands DC voltages of 3270V for 2 seconds between lines. Operating within a temperature range of -25°C to +100°C, it features a chassis mount design with S081 housing configuration.

Power Line Filter Modules Feature Summary

• Provides electromagnetic interference suppression for three-phase power systems in converter applications
• Engineered with robust insulation capable of withstanding high DC voltage stress between lines
• Utilizes a specialized housing structure suitable for integration into industrial power electronic equipment

Power Line Filter Modules Applications

• Industrial motor drive systems
• Power conversion units
• Heavy-duty machinery power supplies

Power Line Filter Modules Procurement Notes

Verify the specific voltage rating requirements against the datasheet, as the component supports both 760V and 440V configurations depending on connection topology. Confirm that the S081 housing style matches the mechanical constraints of the target enclosure. Ensure the operating environment remains within the specified -25°C to +100°C thermal limits to maintain performance integrity.

Power Line Filter Modules Selection Notes

Select this model when high current capacity of 250A is required for three-phase filtering. Consider the physical dimensions and chassis mounting method during layout planning. Evaluate the leakage current characteristics if sensitive downstream equipment is present. Compare against lower current variants in the B84143 series if system loads are significantly reduced.

Power Line Filter Modules Part Context

This component belongs to the B84143K series of three-phase filters from TDK-EPCOS. These filters are specifically engineered for use in converters and power electronics where significant electromagnetic noise reduction is necessary. The series offers various current ratings and housing options to accommodate different industrial power distribution needs.

Power Line Filter Modules Replacement Considerations

Check the B84143B series for similar current ratings with potentially different housing styles. Verify compatibility with the B84143V series for higher power applications if current demands exceed 250A. Ensure any substitute maintains the same three-phase configuration and chassis mounting interface.
