Key Features

• Capacitance & Voltage: 4.7 mF (4700 µF) nominal capacitance with a rated voltage of 550 V and capacitance tolerance of ±20% (at 120 Hz, 20 °C).
• Screw Terminal Package: Radial can with screw terminals for secure electrical and mechanical connection; package case described as radial, can - screw terminals with physical size L: 17 × D: 9 cm.
• High Ripple Current Handling: Rated ripple current of 14.5 A at 120 Hz and 20.3 A at 100 kHz, suitable for circuits with substantial AC ripple components.
• Temperature Range & Endurance: Operates from -25 °C to +85 °C. Specified endurance of 5000 hours at +85 °C when D.C. bias plus rated ripple current is applied (applicable to 500 V and 550 V ratings).
• Leakage Current Specification: After 5 minutes' application of rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (C: µF, V: V).
• Polarized Design: Electrolytic, polarized capacitor suitable for DC bus and filter applications.
• Environmental Compliance & Safety Options: RoHS compliant; flame-retardant electrolyte is available by type for improved safety in critical installations.
• Low‑temperature Stability: Impedance stability specified with Z(-25 °C) / Z(+20 °C) up to 8, supporting performance in colder starts.

Typical Applications

• Industrial Power Supplies (Inverter circuitry): Used as a high-voltage energy storage and smoothing element in inverter and power-supply designs that require sustained ripple current handling.
• Extra‑High Voltage Power Systems: Suited for applications requiring 550 V rated components and robust high-ripple capability.
• General‑Purpose Industrial Equipment: Applicable where a polarized, high-capacitance, high-voltage capacitor is required for filtering, smoothing, or DC link functions.

Unique Advantages

• High Voltage Capability: 550 V rating enables use in extra-high voltage circuits without series-stacking multiple lower-voltage capacitors.
• Strong Ripple Performance: Explicit ripple current ratings at both 120 Hz and 100 kHz allow designers to size capacitors against AC stress across a wide frequency range.
• Specified Endurance Under Real Load: 5000-hour endurance at +85 °C under D.C. bias plus rated ripple current for 500 V and 550 V parts provides a verifiable lifetime metric for system reliability planning.
• Defined Leakage Boundaries: Leakage current guaranteed by a clear formula (3√CV µA or 5 mA max) simplifies design margin and safety assessments.
• Secure Mechanical Termination: Screw-terminal construction supports robust mounting and field serviceability in industrial assemblies.
• Regulatory and Safety Options: RoHS compliance and availability of flame-retardant electrolyte help meet environmental requirements and improve safety choices.
