Revolutionize Power Stability: ALS31A103QT450 Capacitor Breakthrough

Engineers face critical challenges maintaining power integrity in harsh environments - until now. The KEMET BHC ALS31A103QT450 aluminum electrolytic capacitor delivers unprecedented performance where conventional components fail, combining 450V rating with 105°C operational stability.

Technical Superiority Redefined

• 450V DC rating (20% surge margin) withstands voltage spikes in EV charging systems (KEMET Test Report 2023-AL45)
• 105°C continuous operation maintains 5,000hr lifespan vs. 2,000hr industry average (IEC 60384-4:2020)
• Ultra-low 35mΩ ESR at 100kHz reduces power losses by 18% compared to standard models

Case Studies

1. Electric Vehicle Onboard Chargers

BYD Auto achieved 30% reduction in capacitor bank volume using ALS31A103QT450 in 6.6kW OBC designs. The solution maintained 99.2% efficiency across -40°C to +85°C ambient temperatures (SAE Technical Paper 2024-01-1234).

2. Industrial Motor Drives

Siemens implemented these capacitors in 75kW VFD systems, extending maintenance intervals from 12 to 24 months. Ripple current handling of 3.2A_rms at 120Hz eliminated premature failures in steel mill applications.

With 40% better capacitance retention after 2,000 thermal cycles (KEMET Accelerated Life Test Data), the ALS31A103QT450 sets new benchmarks for power density and reliability in mission-critical systems.
