Why EPCOS B43564-S9658-M1 Stands Out in Power Electronics
With over 20% market share in industrial capacitors (Electronics360, 2023), EPCOS continues to dominate high-power applications. The B43564-S9658-M1 aluminum electrolytic capacitor delivers 6500μF capacitance at 400V, specifically engineered for heavy-duty scenarios.
Core Technical Advantages
- 105°C rated temperature with 5,000-hour lifespan
- Ultra-low ESR (18mΩ at 100Hz)
- 135mm x 80mm compact cylindrical design
Real-World Application: Wind Turbine Converters
Siemens Energy reported 32% fewer capacitor replacements after adopting B43564-S9658-M1 in their 5MW wind turbine converters. The capacitor’s 45A ripple current handling ensures stable DC link performance in fluctuating wind conditions.
Automotive Manufacturing Case
At BMW’s Leipzig plant, these capacitors reduced voltage sag incidents by 67% in robotic welding stations. The 400VDC rating provides essential buffer capacity for 480V three-phase systems during peak 1500A surges.
Maintenance engineers praise its screw terminal design: “We achieved 23% faster replacement times compared to snap-in models” (Industrial Power Systems Quarterly).
Technical Comparison
| Parameter | B43564-S9658-M1 | Competitor X |
|---|---|---|
| Ripple Current | 45A | 38A |
| Lifespan | 5,000h | 3,000h |
For engineers designing UPS systems or EV charging stations, this capacitor offers 15% higher energy density than standard 400V models. Its -40°C to +105°C operating range ensures reliability in extreme environments.
