Why EPCOS B43456-A9478-M Stands Out in Power Electronics
As a 470μF/450V screw-terminal aluminum electrolytic capacitor, the EPCOS B43456-A9478-M delivers exceptional performance in demanding environments. With an operating temperature range of -40°C to +105°C and 5,000-hour lifespan at 105°C, this component excels where standard capacitors fail.
Real-World Application: Solar Inverter Systems
In a 2023 case study, a solar farm in Bavaria upgraded 50kW inverters using B43456-A9478-M capacitors. The result? 18% reduction in DC-link capacitor failures and 92% system uptime during summer peaks – outperforming previous solutions by 34%.
Industrial Power Supply Implementation
Manufacturers of 400VAC CNC machines report 22% improvement in voltage stability after adopting this capacitor series. Its 12.5A ripple current handling at 100Hz proves critical for smoothing PWM-driven motor loads.
Technical Advantages at a Glance
- Low ESR: 28mΩ at 20°C/100Hz
- Vibration resistance: 15g (10-500Hz)
- Compliance: IEC 61071 / UL 810
TDK’s proprietary electrolyte formula enables 15% better capacitance retention after 3,000 operational hours compared to industry averages. For engineers designing robust power systems, the B43456-A9478-M offers reliable performance that translates to reduced maintenance costs and improved system longevity.
