• Capacitance & Voltage — 8200 µF (8.2 mF) nominal capacitance with a 350 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Mounting & Package — Screw terminal radial can design for secure bolted connections; package case described as radial can with screw terminals and physical size L: 15 × D: 7.62 cm.
• Temperature Range — Rated for operation from −25°C to +85°C to support equipment used in areas with temperature variation.
• Ripple Current Performance — High ripple capability with specified ripple currents of 26.4 A at 120 Hz and 36.96 A at 10 kHz for demanding power-cycle environments.
• Endurance & Charge–Discharge Reliability — Designed to meet endurance after 5000 hours at 85°C under D.C. bias plus rated ripple current; also validated for 20 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Leakage & Stability — Initial leakage current specification: after 5 minutes, leakage ≤ 3√V (µA) or 5 mA, whichever is smaller; low-temperature impedance stability specified (Z at −25°C / Z at +20°C ≤ 8 for rated voltages).
• Polarized — Polar capacitor suitable for DC smoothing, regenerative and rectifier circuits where polarity is observed.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servo Drives and Motor Control — Handles high-frequency regenerative voltages common in AC servomotor and inverter systems, providing energy capture and smoothing during braking and regeneration.
• General Inverters — Used in inverter DC-link and smoothing stages to support fluctuating supply conditions and high ripple currents.
• Rectifier / Voltage Doubler Circuits — Suitable for rectifier stages and voltage doubler topologies where large capacitance and voltage rating are required for DC smoothing.
• Power Electronics Equipment in Variable-Voltage Areas — Offers robustness for equipment operating in environments with frequent voltage fluctuations, leveraging its endurance and leak current specifications.

Unique Advantages
