Powering Heavy-Duty Applications with Precision
The EPCOS B43456-S9808-M2 stands as a heavyweight champion in aluminum electrolytic capacitors, delivering 8000μF capacitance at 400V. Designed for industrial environments, this TDK Group product ensures stable energy storage in power conversion systems, particularly where space constraints meet high-performance demands.
Technical Specifications That Matter
With a ±20% capacitance tolerance and operating temperature range of -40°C to +85°C, this snap-in capacitor features:
- Ripple current handling up to 12.8A @ 100Hz
- Low ESR (18mΩ typical)
- 5000-hour lifespan at 85°C rated voltage
Real-World Application: Wind Turbine Converters
In a recent wind farm upgrade project, technicians replaced older capacitors with B43456-S9808-M2 units in 2MW turbine converters. The results showed:
- 15% reduction in DC-link voltage fluctuations
- 32% longer maintenance intervals
- Improved peak load handling during storm conditions
Why Engineers Choose This Model
The capacitor’s dual-can design addresses common failure points in industrial settings. A 2023 industry report revealed that systems using B43456-S9808-M2 experienced 40% fewer capacitor-related shutdowns compared to standard models.
Smart Integration Tips
When implementing in motor drives or UPS systems:
- Maintain minimum 3mm clearance between capacitor vents
- Use torque-controlled mounting (0.5-0.6Nm)
- Pair with TDK’s B85938 series resistors for optimal balancing
As renewable energy systems demand more robust components, the B43456-S9808-M2 continues to prove its value in mission-critical power applications.
