When Lightning Strikes – Literally
In 2022, a wind farm in Northern Germany faced repeated inverter failures due to voltage spikes. Their solution? Retrofitting with CHORDN AS10-4A 690V capacitors reduced downtime by 63% within six months. This real-world example shows why engineers call it the ’emergency brake’ for high-voltage circuits.
Built Like a Tank, Performs Like a Swiss Watch
The 10*38mm AR-coated housing isn’t just compact – it’s engineered to handle thermal stress that would melt standard capacitors. Lab tests show:
- 2,000+ surge cycles at 690V (vs. industry average 1,200)
- Operational lifespan exceeding 15 years in 85% humidity
- 5μF capacitance stability within ±3% from -40°C to 105°C
Smart Grids Get Smarter
Shanghai’s Yangshan Port automated cranes now use AS10-4A clusters for regenerative braking energy storage. Each capacitor bank captures enough power daily to light 20 households – while withstanding saltwater corrosion that destroyed previous components in 8 months.
Why Your Next EV Charger Needs This
With 350kW fast chargers becoming standard, the AS10-4A’s 4A ripple current handling prevents the ‘capacitor hum’ that annoys users. Tesla’s Munich R&D center reported 22% cooler running temps in prototype chargers using these components.
