B84143C1000S251

Power Line Filter Modules Overview

The EPCOS B84143C1000S251 is a three-phase EMC power line filter designed for high-current converter applications. It features a rated voltage of 440/760 V AC at 50/60 Hz and supports a continuous current of 1000 A. The unit provides superior attenuation in the 9 kHz to 150 kHz frequency range and includes a short-circuit rating (SCCR) of 100 kA. It utilizes busbar termination and chassis mounting, with dimensions of approximately 710 x 365 x 257 mm.

Power Line Filter Modules Feature Summary

• High attenuation performance across the 9 kHz to 150 kHz frequency spectrum
• Robust short-circuit capability with a 100 kA SCCR rating
• Designed for large current converter environments
• Compliant with IEC 60939-1:2010 leakage current standards

Power Line Filter Modules Applications

• Motor-driven variable frequency drives
• Wind turbine power systems
• Industrial power supply units

Power Line Filter Modules Procurement Notes

Verify the specific suffix S251 confirms the 440/760 V AC rating during procurement. Confirm physical compatibility with busbar connections and chassis mounting requirements. Ensure the 1000 A current capacity aligns with system design limits. Check for required certifications such as UL or CSA depending on regional deployment needs.

Power Line Filter Modules Selection Notes

Select this component when high current handling up to 1000 A is required alongside strict EMC compliance. The S251 variant is appropriate for higher voltage networks compared to lower-rated series. Consider the compact housing design relative to the high current capacity. Verify thermal management requirements given the high-power application context.

Power Line Filter Modules Part Context

This part belongs to the B84143C*S250/S251 series from TDK Electronics. The series targets demanding industrial power electronics. It replaces older EPCOS designs with enhanced attenuation and safety ratings. The product line emphasizes reliability in renewable energy and heavy industrial sectors.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other B84143C series variants with matching current and voltage ratings. Verify equivalent attenuation curves and physical dimensions before substitution. Cross-reference with B84143B or B84143V series only if electrical parameters are adjusted accordingly.
