Key Features

• Capacitance & Voltage — 4.7 mF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Electrical Loss and ESR — Specified tanδ (DF) of 0.15 and equivalent series resistance of 150 mΩ at 120 Hz to help manage dissipation and thermal rise under ripple conditions.
• Ripple Current Capability — Rated ripple current of 18.3 A at 120 Hz and 25.62 A at 10 kHz for handling AC ripple in power-conversion and regenerative circuits.
• Long Endurance — 5000 hours rated life at 85°C when subjected to DC bias plus rated ripple current; endurance characteristics specify capacitance change within ±20%, tanδ within 300% of initial value, and leakage current ≤ initial specified value after test.
• Temperature Range & Low-Temperature Stability — Operating range of −25°C to +85°C; impedance ratio Z(−25°C)/Z(+20°C) ≤ 8 for rated voltages between 350 V and 450 V.
• Robust Mechanical Package — Screw-terminal, radial can package (φ76.2 × 110L) with M5 bolt nominal terminal; packaged in cardboard and available in mass production.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current not more than 3√(V) µA or 5 mA, whichever is smaller (measured at 20°C).
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Regenerative Circuits — Provides bulk energy storage and ripple handling for high-frequency regenerative voltage in servo drive systems.
• General Inverters — Suited for DC-link and smoothing duties in inverter topologies where 400 V rating and high ripple capability are required.
• Equipment in Voltage-Fluctuating Areas — Handles fluctuating supply conditions with endurance at elevated temperature and specified leakage and impedance behavior.
• Rectifier Circuits (Voltage Doubler) — Appropriate for rectifier and voltage-doubler circuits that demand high capacitance and stable performance under repeated charge–discharge cycles.

Unique Advantages

• High Capacitance at High Voltage: 4700 µF at 400 V provides significant energy buffering for power-electronics applications requiring both voltage withstand and bulk storage.
• Designed for High Ripple: Specified ripple currents at 120 Hz and 10 kHz reduce the need for parallel components and manage thermal load within system designs.
• Low ESR and Controlled Loss: 150 mΩ ESR and tanδ of 0.15 at 120 Hz help minimize internal dissipation and support stable operation under continuous ripple loading.
• Durable Endurance: 5000-hour life at 85°C under DC bias plus rated ripple current ensures predictable degradation behavior for long-term installations.
• Secure, High-Current Termination: Screw-terminal radial can with M5 bolt nominal terminals provides reliable mechanical and electrical connection for heavy-current power circuits.
• Regulatory Compliance: RoHS conformity supports environmental and regulatory requirements for industrial equipment.
