The LNY2G182MSEGBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNY series. It delivers 1800 µF capacitance at a 400 V rating in a radial can with robust screw terminals, offering a high-capacitance solution for power electronics.

Designed for general-purpose industrial and power-supply applications, this part targets use cases that require high voltage, substantial ripple handling and long endurance at elevated temperatures.

Key Features

• High Voltage and Capacitance: 1800 µF capacitance rated at 400 V, suitable for DC link and bulk energy storage in high-voltage circuits.
• Screw-Terminal Mounting: Radial can with screw terminals provides secure electrical and mechanical connection for heavy-current applications and serviceability.
• High Ripple Handling: Low-frequency ripple current 9.1 A (120 Hz) and high-frequency ripple current 12.74 A (10 kHz) to support power conversion and filtering duties.
• Endurance at Elevated Temperature: Rated life of 2000 hours at 85°C under specified ripple conditions for predictable long-term performance.
• Loss Characteristics: Tan δ of 0.25 (measured at 20°C, 120 Hz) and capacitance tolerance ±20% for design margining and AC performance assessment.
• Leakage Current: Rated leakage current listed as 2540 µA, enabling designers to budget pre-charge and bleed requirements.
• Environmental Compliance and Packaging: RoHS compliant and supplied in cardboard packing; product status: mass production.
• Operating Range: Specified for −40°C to +85°C to cover a wide range of industrial ambient conditions.
• Form Factor: Physical size φ63.5 × 65 mm (L: 6.5 × D: 6.35 cm) for compact high-capacitance installations.

Typical Applications

• Power Supplies: Bulk energy storage and DC link smoothing in high-voltage switch-mode power supplies that require stable capacitance and high ripple current capability.
• Inverters and Motor Drives: DC bus filtering and pulse-energy buffering where 400 V rating and high ripple endurance help maintain voltage stability under load.
• Industrial Power Electronics: Energy storage and filtering in converters and industrial equipment that need durable screw-terminal connections and extended life at 85°C.

Unique Advantages

• High-capacitance density for downsizing: 1800 µF at 400 V helps reduce the number of capacitors required, supporting equipment size reduction initiatives.
• Robust electrical and mechanical connections: Screw-terminal construction simplifies wiring for high-current paths and eases serviceability in the field.
• Designed for ripple-heavy environments: Specified low- and high-frequency ripple currents (9.1 A / 12.74 A) reduce thermal stress and improve reliability in switching applications.
• Predictable life at elevated temperature: 2000-hour endurance rating at 85°C provides designers with a clear reliability target for thermal and load planning.
• Regulatory compliance: RoHS compliance supports use in regions and projects with restricted-substance requirements.
