Unique Advantages

• Very high capacitance: 330000 µF provides substantial bulk energy storage in a single component, reducing the number of parts required for the same capacitance.
• High ripple current ratings: 31.2 A (120 Hz) and 35.88 A (100 kHz) support designs with significant AC ripple without exceeding rated limits.
• Long rated life at elevated temperature: 5000 hours at 85°C offers predictable aging characteristics for long-running systems.
• Screw-terminal package: Robust mechanical and electrical connection method suitable for high-current installations and repeatable serviceability.
• Clear electrical specifications: Defined leakage (5000 µA) and dissipation factor (tan δ 0.6 at 20°C, 120 Hz) enable accurate thermal and performance planning.
• RoHS compliant: Meets RoHS requirements for use in compliant manufacturing environments.
