• Large Capacitance: 8.2 mF nominal capacitance with ±20% tolerance for energy buffering and smoothing in power stages.
• High Temperature Endurance: Rated for operation from –40°C to +105°C with a load life of 5000 hours at 105°C under ripple current.
• High Ripple Current Capability: Handles 23.1 A at 120 Hz and 32.34 A at 10 kHz, supporting heavy AC ripple and high-frequency switching environments.
• Screw Terminal Mounting: Radial can with screw terminals for secure, low-impedance electrical connections in industrial assemblies.
• Compact Series Design: LNU series is specified as high-voltage and smaller-sized than LNT, providing space-efficient installation for power modules.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for regulatory compliance.

Typical Applications

• Industrial Inverter Power Supplies: Energy storage and smoothing for inverter front-ends where high-voltage filtering and stable capacitance are required.
• AC Servomotor Regenerative Circuits: Handles high-frequency regenerative voltage and high-speed charge–discharge cycles common in motor drive systems.
• General Inverter Systems: Bulk energy buffering and ripple suppression for grid-tied and isolated inverter topologies.
• High-Frequency Switching Power Supplies: Supports designs with significant ripple and switching stress thanks to elevated ripple current ratings and high-temperature life.

Unique Advantages

• Engineered for High-Voltage Power Electronics: 400 V rating and series support to 525 V provide margin for high-voltage designs without changing capacitor family.
• High Ripple Endurance: Specified ripple current values at both low and high frequencies enable reliable operation in switching and regenerative environments.
• Long High-Temperature Life: 5000 hours at 105°C under rated ripple conditions helps ensure long-term stability in hot industrial enclosures.
• Secure Screw-Terminal Connections: Screw-terminal radial can package simplifies mechanical mounting and provides robust electrical connections for heavy-current paths.
• Space-Conscious Series Design: Smaller sized within the series helps optimize board- and chassis-layout in compact power assemblies.
• Regulatory Compliance: RoHS conformity supports deployment in environments requiring restricted-substance compliance.
