AKKN ElectronicsSolving Modern Power Challenges
In industrial power systems requiring 300-500V operation, engineers face:
- Voltage ripple compromising control systems
- Thermal stress reducing component lifespan
- Space constraints limiting capacitance values
The EPCOS B43564-S9378-M2 aluminum electrolytic capacitor addresses these challenges through optimized engineering.
Technical Breakthroughs
- 3700μF capacity ±20% (TDK/EPCOS datasheet) ensures stable energy reserves for motor drives
- 400V DC rating withstands industrial voltage spikes (IEC 61071 verified)
- 45mm × 80mm compact design saves 22% PCB space vs comparable units
- 5000hr lifespan @ 85°C (EPCOS aging tests) reduces maintenance frequency
Case Studies
1. CNC Machine Power Stabilization
Shanghai-based OEM Jinsheng Machinery implemented B43564 capacitors in their 450V spindle drives:
- Reduced voltage ripple from 12% → 3.8% (machine logs)
- Extended maintenance intervals from 6 → 18 months
2. EV Fast Charger Deployment
German charging network E-Move achieved:
- 96.2% charge efficiency @ 350kW (TÜV Rheinland certification)
- 32% lower capacitor operating temps vs previous solution
"The ripple current handling (8.3A RMS) proved critical for our 24/7 stations," noted E-Move's Lead Engineer.
