• High Ripple Capability  Low-frequency ripple current of 18.5 A (120 Hz) and high-frequency ripple current of 25.9 A (10 kHz), enabling robust handling of both line-frequency and high-frequency switching currents.
• Thermal and Lifetime  Designed for continuous operation from –40°C to +105°C with a rated load life of 5000 hours at 105°C under rated ripple conditions.
• Low Loss Characteristics  Rated tangent of loss angle (tanδ) of 0.2, supporting efficient performance in AC and DC filtering and pulse charge–discharge cycles.
• Leakage Current  Specified leakage current of 4360 µA after initial application, aligning with high-voltage capacitor expectations for power systems.
• Robust Mechanical Package  Radial can with screw terminals (φ63.5 × 165 mm length) for secure mounting and high-current connections; packaged for mass production with cardboard packing.
• Regulatory Compliance  RoHS compliant per the product information provided.

Typical Applications

• Industrial Power Supplies  Used in inverter-side DC link and bulk energy storage where high voltage and sustained ripple endurance are required.
• Motor Drive / Servo Systems  Suited for AC servomotor regenerative circuits and general inverter applications that demand high-frequency charge–discharge capability.
• High-Frequency Regenerative Systems  Applicable where high-frequency ripple currents and rapid charge-discharge cycles are present, leveraging the capacitor's high ripple ratings and low tanδ.
• General-Purpose Power Electronics  Fits designs requiring robust high-voltage capacitance in a screw-terminal, radial-can format for ease of installation and replacement.

Unique Advantages

• High-voltage in a compact form: Provides 450 V rated performance in a design described as high-voltage and smaller-sized within the LNU series, enabling tighter packaging in power systems.
• Strong ripple-handling: High specified ripple currents at both low and high frequencies (18.5 A @120 Hz, 25.9 A @10 kHz) reduce stress on upstream components and improve system resilience under switching loads.
• Long high-temperature life: 5000 hours endurance at 105°C under rated ripple conditions supports reliable operation in thermally demanding installations.
• Screw-terminal robustness: Screw terminals offer secure electrical connections and mechanical stability for high-current bus applications and field serviceability.
• Low dissipation: tanδ of 0.2 helps minimize power loss in filtering and energy-storage roles, improving overall efficiency of the power stage.
• Production-ready packaging: Supplied for mass production with cardboard packing to facilitate handling and assembly in volume manufacturing environments.
