Slash EMI Noise 60dB: EPCOS B84111-A-B120 Filter Breakthrough

Industrial engineers face growing challenges with electromagnetic interference (EMI) in high-power systems. The EPCOS B84111-A-B120 three-phase power filter delivers 60dB insertion loss at 10MHz (TDK Datasheet 2023), setting new standards for noise suppression in mission-critical applications.

Technical Superiority Redefined

• 120A continuous current rating supports heavy industrial loads (IEC 60939-2 certified)
• -40°C to +100°C operating range ensures reliability in extreme environments
• Compact 184×72×64mm design saves 35% panel space vs competitors

Case Studies

1. Robotic Assembly Line Upgrade

A German automotive manufacturer reduced PLC communication errors by 82% after installing B84111-A-B120 filters in their 480V motor drives. Production downtime decreased from 3.2 to 0.7 hours weekly (2023 plant maintenance report).

2. Wind Turbine Power Conversion

Norwegian energy company measured 54dB EMI reduction in 690V wind turbine converters using these filters. Grid compliance testing passed 23% faster (DNV GL field test data).

With UL/ENEC/CQC certifications, this filter solution enables 24/7 operation across manufacturing, energy, and transportation sectors while meeting global safety standards.
