Key Features

• Capacitance and Voltage — 8200 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for high-voltage power systems.
• Low Dissipation Factor — tan δ = 0.15 at 20°C, 120 Hz, indicating relatively low AC loss for filtering and smoothing applications at line frequency.
• High Ripple Current Capability — Rated ripple currents of 27.8 A at 120 Hz and 38.92 A at 100 kHz, supporting substantial AC ripple in rectifier, inverter and regenerative circuits.
• Long Endurance — 5000 hours at 85°C under rated conditions, meeting endurance requirements for sustained operation in demanding environments.
• Wide Operating Temperature Range — Specified for −25°C to +85°C to accommodate a range of industrial ambient conditions.
• Screw Terminal / Radial Can Package — φ90 × 130L physical package with screw terminals (M5 nominal for φ90 size), providing secure, low-resistance connections and robust mechanical mounting.
• Leakage Current — Specified leakage current up to 5000 µA as provided, suitable for high-voltage power designs where leakage is accounted for.
• RoHS Compliant — Meets RoHS directive requirements noted in the product series documentation.

Typical Applications

• AC Servomotor and Inverter Regeneration — Suited for high-frequency regenerative voltage storage in AC servomotor and general inverter systems.
• Voltage-Doubler and Rectifier Circuits — Applicable to rectifier circuits such as voltage doubler topologies that require high-voltage bulk capacitors.
• Equipment in Fluctuating-Voltage Areas — Designed for use in systems exposed to variable input voltages where robust energy buffering is needed.
• General Power Electronics — Bulk smoothing, filtering and charge–discharge applications in industrial power supplies and motor drives.

Unique Advantages

• Large Energy Storage: 8200 µF at 400 V supplies significant bulk capacitance for energy buffering and smoothing in high-voltage circuits.
• Measurable Low Loss: Low dissipation factor (tan δ = 0.15 at 20°C, 120 Hz) reduces heat generation and improves efficiency in AC filtering applications.
• High Ripple Handling: Specified ripple currents of 27.8 A (120 Hz) and 38.92 A (100 kHz) enable handling of substantial AC ripple across a range of frequencies.
• Durability at Elevated Temperature: 5000 hours endurance at 85°C supports long-term reliability under continuous operation at rated conditions.
• Secure Screw-Terminal Connection: Radial can with screw terminals (φ90 size uses M5) offers robust electrical and mechanical attachment for industrial assemblies.
• Designed for Fluctuating Voltage Environments: Series guidance specifies suitability for equipment operating where voltage varies, supporting regenerative and rectifier use cases.
