The Silent Hero in High-Voltage Applications
When engineers at a European wind turbine manufacturer faced repeated failures in their power converters, they turned to KEMET’s BHC ALS31A222MF400 capacitors. The result? A 40% reduction in maintenance calls and 18 months of uninterrupted operation – proving that component choice matters more than ever in harsh environments.
Built Tough for Real-World Challenges
This 2200μF/400V aluminum electrolytic capacitor isn’t your average energy storage component. With its screw terminal design and -40°C to +85°C operating range, it’s become the go-to solution for:
- Industrial motor drives surviving 24/7 production cycles
- Solar inverters maintaining 98.5% efficiency in desert installations
- EV charging stations withstanding 100,000+ charge cycles
Case Study: Breathing New Life into Aging Infrastructure
A Midwest steel mill recently upgraded their 1980s-era rolling mill drives using these capacitors. The retrofit achieved:
| Energy recovery efficiency | +22% |
| Harmonic distortion | -31% |
| Component lifespan | 2.8× original spec |
‘We’ve eliminated $150k annual capacitor replacement costs,’ reported their chief engineer during a recent industry webinar.
Why Designers Keep Choosing This Workhorse
With 5,000-hour lifespan at 85°C and vibration resistance up to 15G, the ALS31A222MF400 outperforms generic alternatives. KEMET’s proprietary electrolyte formula enables stable ESR (<35mΩ) even after 3 years of continuous operation – a critical factor in mission-critical systems.
As renewable energy projects scale globally, components like these become the unsung heroes enabling our electrified future. The question isn’t whether to use industrial-grade capacitors, but which ones can truly deliver on their promises.
