How Cornell Dubilier’s CDE 381LQ331M450A032 Solves High Voltage Filtering Challenges in Power Supplies

When it comes to high-performance power supplies, engineers often face the challenge of filtering out unwanted noise and ensuring stable voltage levels. The Cornell Dubilier – CDE 381LQ331M450A032 is a game-changer in this area. This aluminum electrolytic capacitor is specifically designed for applications requiring high ripple current and reliable performance under demanding conditions. With a capacitance of 330µF and a voltage rating of 450V, it offers an impressive ripple current capability of up to 2.8A at 100Hz (based on manufacturer specifications). These features make it ideal for industrial power supplies, motor drives, and renewable energy systems where efficiency and longevity are critical.”One real-world example involves its use in solar inverters. In these systems, the CDE 381LQ series helps smooth out DC link voltages, reducing harmonic distortion and improving overall system efficiency by around 2-3%. Its long life expectancy—rated for over 2000 hours at 85°C—ensures minimal downtime even in hot environments like outdoor solar installations or enclosed industrial equipment. Additionally, the compact design of the 381LQ series allows for space-saving implementations without compromising performance.\
