• Wide Operating Temperature — Specified for operation from −25°C to +105°C, suitable for elevated-temperature environments consistent with its high-voltage rating.
• Long Load Life — Rated load life of 5,000 hours at 105°C under rated ripple conditions, supporting reliable long-term operation.
• Polarized Electrolytic — Polarized construction for DC applications; capacitance tolerance ±20% at 120 Hz, 20°C.
• RoHS Compliant — Meets RoHS directive requirements.
• Large Form Factor — Mechanical footprint φ90 × 250L (size listed as L: 25 × D: 9 cm) with a maximum seated height of 9.843 inch, providing high energy density per part.

Typical Applications

• Power Conversion and Inverters — Bulk DC-link and smoothing for converters where high voltage and large capacitance are required to stabilize DC rails.
• Industrial Power Supplies — Energy storage and ripple suppression in high-voltage, high-current industrial power supplies and converters.
• Uninterruptible Power Supplies (UPS) — Bulk storage for maintaining DC bus stability and supporting transient load demands.
• Motor Drives and Power Electronics — Energy buffering and ripple management in drive electronics that demand secure screw-terminal connections and high ripple capability.

Unique Advantages

• High energy storage at elevated voltage: 15,000 µF at 450 V gives large stored energy per component for compact system design.
• Robust electrical performance under ripple: Specified ripple currents of 45.6 A (120 Hz) and 63.84 A (100 kHz) reduce the need for parallel devices when handling high AC stress.
• Screw-terminal reliability: Screw terminals provide mechanically secure, low-impedance connections well suited to high-current applications.
• Operational endurance at 105°C: 5,000-hour rated life at 105°C supports applications with sustained elevated temperatures.
• Clear marking and compliance: Marked with white lettering on a black sleeve and RoHS compliant for easier identification and environmental conformity.
• Large physical format for high power systems: φ90 × 250L construction (L: 25 × D: 9 cm) accommodates the high capacitance and voltage rating in a single part.
