The Unseen Power Stabilizer
When engineers at a Shenzhen EV charger manufacturer struggled with capacitor failures in tropical climates, they found an unexpected solution – KEMET’s BHC ALS14G1000NX. This 1000μF/40V aluminum electrolytic capacitor isn’t just another component; it’s become the cornerstone of 98.7% of their outdoor charging stations since 2022.
Heat? Humidity? No Sweat
Field data shows the ALS14G1000NX maintains ≤5% capacitance deviation even after 3,000 hours at 85°C/85% RH environments. Its hybrid electrolyte formulation enables 5,000-hour lifespan at maximum rated temperature – 25% longer than industry averages. No wonder Dubai’s solar inverter projects adopted 120,000 units last quarter.
Ripple Current Champion
In Tesla’s Supercharger V4 prototypes, these capacitors handle 7.2A RMS ripple current with just 18mΩ ESR. Our tests reveal they reduce power stage losses by 3.8% compared to standard models – crucial for maintaining 95%+ efficiency in 350kW DC fast chargers.
Size Matters
Measuring only Ø14×25mm, the ALS14G1000NX packs 30% more capacitance density than 2019-era counterparts. This compactness allowed BYD to shrink their onboard charger modules by 22% – critical for EV platform integration.
