Key Features

• High Capacitance and Voltage: 4.7 mF (4700 µF) nominal capacitance rated at 400 V to support high-voltage power circuitry.
• Screw-Terminal Package: Radial can with screw terminals for robust, high-current connections and secure mounting in power assemblies.
• High Ripple Current: Low-frequency ripple current of 12.6 A (120 Hz) and high-frequency ripple current of 17.64 A (100 kHz) to accommodate demanding ripple loads.
• Long Endurance: Rated for 20,000 hours at +85°C under the specified ripple conditions, enabling extended service life in continuous-duty systems.
• Loss Angle (tan δ): tanδ = 0.2 (measured at 20°C, 120 Hz), providing a defined dissipation characteristic for thermal and stability planning.
• Leakage Current: Specified leakage current of 4110 µA, allowing designers to account for quiescent losses in system budgets.
• Temperature Range: Operates from −25°C to +85°C, suitable for typical industrial ambient conditions covered by the LNX series.
• RoHS Compliant & Packaging: RoHS-compliant construction and shipped in cardboard packing for production volumes.
• Compact High-Voltage Form Factor: Physical size φ63.5 × 170 mm provides a high-energy density solution in a screw-terminal can.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in industrial supplies and power conversion systems where high-voltage, high-capacitance components are required.
• Inverter and Motor Drive Circuits: DC-link and intermediate bus filtering for inverter circuitry that demands high ripple current capability and reliability.
• High-Voltage Power Electronics: Energy buffering and decoupling in high-voltage assemblies that benefit from screw-terminal connections and long endurance.

Unique Advantages

• High Current Handling: Specified ripple currents at both low and high frequencies reduce thermal stress and help maintain performance under demanding load conditions.
• Extended Life Rating: 20,000 hours at 85°C under rated ripple conditions supports long service intervals and lower maintenance for continuous-duty systems.
• Robust Mechanical Connection: Screw-terminal mounting provides reliable, low-resistance connections for high-current paths, simplifying assembly in power racks and modules.
• Measurable Dissipation Characteristics: Defined tanδ (0.2 at 20°C, 120 Hz) and known leakage current enable accurate thermal and leakage budgeting in design stages.
• Series-Level Reliability: Part of Nichicon’s LNX series, which is specified for high ripple and extra-high-voltage applications, aligning series characteristics with system requirements.
• Regulatory Compliance: RoHS compliance supports use in markets and products that require restricted-substance adherence.
