LNC2G392MSEHBN

The LNC2G392MSEHBN is a screw-terminal aluminum electrolytic capacitor designed for power-electronic applications that require high-voltage energy buffering and high ripple handling. It features a 3.9 mF (3900 µF) capacitance at a 400 V rating in a compact radial can with screw terminals.

Engineered for industrial power supplies and inverter/regenerative circuits, this capacitor balances high ripple-current capability with a long load life (5000 hours at 85°C), making it suitable for inverter circuitry, AC servomotor regenerative voltage and general-purpose power electronics.

Key Features

• Electrical Performance: 3.9 mF (3900 µF) nominal capacitance with ±20% tolerance and a rated voltage of 400 V; dissipation factor (tan δ) specified at 0.2.
• High Ripple Current Capability: Rated ripple current of 17.1 A at 120 Hz and 23.94 A at 100 kHz to support high-frequency and low-frequency ripple in power circuits.
• Endurance & Reliability: Load life specified at 5000 hours when subjected to rated ripple current at 85°C; designed to meet endurance and leakage limits after the life test.
• Charge–Discharge Handling: Constructed to cope with high-speed charge–discharge loading and high-frequency regenerative voltages used in servo and inverter applications.
• Temperature Range: Operates from −40°C to +85°C to cover a broad set of industrial ambient conditions.
• Mechanical & Packaging: Radial can with screw terminals, physical size approximately φ76.2 × 80L (L: 8 × D: 7.62 cm), supplied in cardboard packing for bulk handling.
• Leakage Current: Specified leakage current value of 3.74 mA (per product description) after initial application of rated voltage.
• Environmental Compliance: RoHS compliant per the product data.

Typical Applications

• Industrial Power Supplies: Energy buffering and smoothing in inverter front-ends where high voltage and sustained ripple handling are required.
• Inverter and Regenerative Drives: Support for high-frequency regenerative voltage in AC servomotor and general inverter systems, including charge–discharge cycles.
• General Purpose Power Electronics: Bulk energy storage and ripple suppression for converters, DC link circuits, and other power-conditioning equipment.

Unique Advantages

• High Voltage Rating: 400 V nominal rating enables use directly in high-voltage DC link and inverter circuits without additional series stacking.
• High Ripple Capability in Compact Form: Designed to deliver high ripple current (17.1 A @120 Hz, 23.94 A @100 kHz) in a relatively small radial can (φ76.2 × 80L), aiding density-sensitive designs.
• Long Operational Life: 5000-hour load life at 85°C under rated ripple current provides predictable longevity for industrial applications.
• Robust Thermal Range: −40°C to +85°C operating range supports a wide set of industrial ambient conditions.
• Screw-Terminal Mounting: Screw terminals simplify secure electrical connections and installation in power assemblies and serviceable equipment.
• Standards-Conscious Construction: Leakage, tan δ and endurance characteristics are specified and tested in accordance with the series datasheet requirements.
