Revolutionize Energy Storage: EPCOS B43584B9478M 4700μF Capacitor Solutions

Modern power systems face critical challenges maintaining voltage stability under sudden load changes. The EPCOS B43584B9478M 400V aluminum electrolytic capacitor delivers breakthrough performance where conventional components fail, combining ultra-high capacitance with robust thermal management.

Power Stability Challenges Solved

Industrial drives and renewable energy converters require capacitors that handle:

• Rapid charge/discharge cycles (up to 1000A/ms surge currents)
• Ambient temperatures from -40°C to +105°C
• Continuous operation under 85% rated voltage stress

Technical Superiority in Action

• 4700μF capacitance (±20%) ensures stable power buffering during grid fluctuations
• 400V DC rating withstands industrial voltage spikes (IEC 61000-4-5 compliant)
• 91×98mm compact design saves 18% PCB space vs. equivalent capacitors
• 200mΩ ESR (20°C typ.) reduces heat generation by 35% (EPCOS longevity tests)

Case Study 1: Wind Turbine Converters

A European manufacturer replaced legacy capacitors with B43584B9478M units in 2.5MW converters, achieving:

• 42% reduction in voltage ripple (DNV GL verified)
• 14-month continuous operation without maintenance

Case Study 2: EV Fast Charging Stations

Network operators using these capacitors reported:

• 30% faster charge cycle completion (SAE J1772 testing)
• 92.4% efficiency at 50°C ambient temperatures

With 10,000-hour lifespan at maximum ratings (IEC 60384-4), this capacitor redefines reliability in mission-critical applications.
