Key Features

• Capacitance & Tolerance — 3.3 mF (3300 µF) with ±20% tolerance (120 Hz, 20°C).
• High Voltage Rating — Rated at 500 V DC with a rated voltage range up to DC 525 V for the LNU series.
• High Temperature Endurance — Rated for continuous operation up to 105°C with a specified load life of 5000 hours when subjected to rated ripple current at 105°C.
• Ripple Current Capability — Specified ripple current: 10.9 A at 120 Hz and 15.26 A at 10 kHz, supporting high-frequency and high-ripple applications.
• Charge–Discharge Durability — Engineered to cope with high-speed charge–discharge loading and tested for endurance under charge–discharge cycles as described in the series specifications.
• Robust Screw-Terminal Package — Radial can with screw terminals provides secure, low-resistance connections for industrial power assemblies; nominal bolt diameter for the series is M5.
• Leakage & Insulation — Leakage current specification: after 5 minutes at rated voltage not more than 3√(C·V) μA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — DC link and smoothing in inverter power modules where high voltage and long life at elevated temperatures are required.
• AC Servomotor Regenerative Circuits — Handling high-frequency regenerative voltage in servo drives and related motor-control systems.
• General Inverter Systems — Bulk energy storage and high-speed charge–discharge cycles in general inverter designs.
• High-Frequency Power Electronics — Applications that require stable ripple performance at both low and high frequencies (specified ripple current at 120 Hz and 10 kHz).

Unique Advantages

• High-voltage capability: 500 V rating (series up to DC 525 V) supports demanding industrial power topologies.
• Compact high-voltage design: Part of the LNU series which is specified as high voltage and smaller sized than comparable LNT devices, enabling space-efficient assemblies.
• Long-term thermal reliability: 5000-hour load life at 105°C under rated ripple conditions provides predictable endurance in hot operating environments.
• High ripple and frequency performance: Rated ripple currents of 10.9 A (120 Hz) and 15.26 A (10 kHz) support both low- and high-frequency power stages.
• Secure screw-terminal mounting: Radial can with screw terminals and M5 nominal bolt diameter for robust mechanical and electrical connections in industrial builds.
• Regulatory compliance: RoHS-compliant construction supports environmental requirements for many industrial systems.
