Revolutionize Power Systems: EPCOS B43456-S9808-M2 8000μF 400V Capacitor Solutions

Modern power electronics face relentless demands: voltage instability in renewable energy converters, thermal stress in industrial motor drives, and efficiency losses in EV charging systems. The EPCOS B43456-S9808-M2 aluminum electrolytic capacitor delivers breakthrough performance where conventional components fail.

Technical Specifications That Redefine Reliability

• 8000μF capacitance ±20% - Stores 18% more energy than standard 400V models (TDK-EPCOS datasheet) for stable voltage buffering
• 400V DC rating - Withstands 450V surge voltages (IEC 60384-4 certified) in unstable grid conditions
• 12.8A ripple current @85°C - Handles high-frequency switching losses in 20kHz+ inverters
• 18mΩ ESR @100Hz - Reduces heat generation by 30% compared to previous-gen capacitors
• -40°C to +105°C range - Maintains capacitance within ±15% across industrial environments
