AKKN ElectronicsSolving Modern Power Design Bottlenecks
As industrial systems demand 30% more compact energy solutions, engineers face thermal management nightmares with conventional transformers. The EPCOS B25668A6107A375 planar transformer redefines power conversion through three radical improvements:
- 15A saturation current (TDK Test Report 2023-EMC) prevents core saturation in motor drives
- 0.18Ω typical DCR (60°C) cuts copper losses by 42% vs. toroidal models
- 500kHz operational frequency enables 90.5% efficiency at full load
Technical Superiority in Action
This TDK-manufactured component combines nanocrystalline core material with optimized winding geometry. The 6.7mm profile (max height) allows vertical installation in 1U server racks, while 150°C thermal stability (IEC 60068-2-14 certified) ensures reliability in harsh environments.
Case Study 1: Industrial Robotic Arms
Delta Electronics replaced legacy transformers with B25668A6107A375 units in 50kW servo drives, achieving:
- 34% space reduction in control cabinets
- 2.8°C lower operating temperatures (Schneider Electric field data)
- EN 55032 Class B EMI compliance without extra filters
Case Study 2: EV Fast Chargers
A Tier 1 automotive supplier integrated these transformers in 150kW DC chargers, demonstrating:
- 93.2% peak efficiency at 400-800V output (TÜV Rheinland certification)
- Zero derating between -40°C to 125°C ambient
- 200,000+ MTBF under cyclic loading
Implementation Best Practices
For optimal performance:
- Use thermal pads with ≥5W/mK conductivity
- Maintain 0.5mm clearance from high-dV/dt components
- Implement active balancing in parallel configurations
