LNY2V123MSEJBB

The LNY2V123MSEJBB is a Nichicon LNY series aluminum electrolytic capacitor in a screw-terminal can package. It delivers 12,000 µF at 350 V with a compact φ90 × 110 mm can, targeting general-purpose high-voltage power applications where high bulk capacitance and robust terminal connections are required.

Designed for equipment downsizing, this part combines high capacitance, strong ripple-current capability and a rated life of 2000 hours at 85°C to support demanding power-rail smoothing and energy-storage roles in industrial and power-system designs.

Key Features

• High Capacitance: 12,000 µF nominal capacitance (±20% at 20°C, 120 Hz) for substantial bulk energy storage and smoothing on high-voltage DC rails.
• 350 V Rated Voltage: Rated for 350 V operation to support high-voltage power supply and DC link applications.
• Robust Screw-Terminal Package: Radial can with screw terminals for secure, high-current connections and straightforward mounting in heavy-duty power assemblies.
• High Ripple Current Handling: Low-frequency ripple current of 24.1 A (120 Hz) and high-frequency ripple current of 33.74 A (10 kHz) to manage continuous and switching ripple stresses.
• Endurance: Load life of 2000 hours at 85°C with rated ripple current applied, supporting extended-duty power systems.
• Operating Temperature Range: −40°C to +85°C to accommodate a broad range of industrial environments.
• Leakage and Loss Characteristics: Leakage current specified at up to 5,000 µA; tangent of loss angle (tanδ) specified at 0.25 under measurement conditions (20°C, 120 Hz).
• Compliance and Availability: RoHS compliant and in mass production; packaged in cardboard for shipping.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing on 350 V DC rails where high capacitance is required.
• Equipment downsizing: High capacitance in a compact screw-terminal can to help reduce overall system volume without sacrificing storage.
• Industrial power modules: Filtering and ripple management in heavy-duty power assemblies that demand secure screw-terminal connections and high ripple capability.
• High-voltage power supplies: Energy buffer and decoupling in 350 V class supply rails to stabilize voltage under load transients.

Unique Advantages

• Substantial bulk capacitance: 12,000 µF provides significant energy storage for smoothing and transient support.
• High ripple tolerance: Rated for 24.1 A at 120 Hz and 33.74 A at 10 kHz, enabling reliable operation under continuous and switching ripple conditions.
• Durable electrical life: 2000 hours at 85°C under rated ripple current supports long-term operation in demanding environments.
• Secure electrical connection: Screw-terminal mounting ensures robust, low-resistance terminations for high-current applications.
• Wide ambient range: −40°C to +85°C operation for broad industrial deployment.
• Regulatory readiness and supply status: RoHS compliant and available in mass production with cardboard packing for straightforward procurement.
