Key Features

• High Voltage Rating — Rated for 525 V DC to support high-voltage power conversion and inverter circuits.
• Capacitance and Tolerance — 2200 µF (2.2 mF) with ±20% tolerance (measured at 120 Hz, 20°C) for bulk energy storage and smoothing.
• Low Loss (tan δ) — tan δ = 0.2 (measured at 20°C, 120 Hz) for predictable AC performance.
• High Ripple Current Capability — Low-frequency ripple current of 9.2 A at 120 Hz and high-frequency ripple current of 12.88 A at 10 kHz, enabling sustained ripple loading.
• Leakage Current — Specified leakage current of 3220 µA after standard voltage application, suitable for high-voltage systems.
• Extended High‑Temperature Life — 5000 hours load life at 105°C under rated ripple conditions for long-term reliability in hot environments.
• Robust Mechanical Mounting — Stud bolt mount with screw terminals (radial can) simplifies secure installation in power assemblies.
• Compact High‑Voltage Form Factor — φ76.2 × 100 mm package (D: 7.62 cm × L: 10 cm) offering high voltage in a smaller footprint compared with larger variants.
• Polarized — Designed as a polarized electrolytic capacitor for DC energy storage applications.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage in high-voltage industrial DC power supplies and converters.
• Inverter and Motor Drive Circuits — DC link and regenerative energy handling for AC servomotor and general inverter systems.
• High‑Frequency Regenerative Systems — Supports high-speed charge–discharge and high-frequency regenerative voltages in drive electronics.
• General Purpose Power Electronics — Use where polarized, high-voltage capacitance and elevated ripple-current capability are required.

Unique Advantages
