LNY2V392MSEFBN

The LNY2V392MSEFBN is an aluminum electrolytic capacitor in Nichicon’s LNY series, featuring a screw terminal radial can design and a rated capacitance of 3.9 mF at 350 V. It is engineered for general-purpose power applications that require high-voltage bulk energy storage and robust ripple current handling in a compact form factor.

Designed for equipment downsizing and extended operation, this component offers a 2000-hour load life at 85°C, RoHS compliance, and a wide operating temperature range from −40°C to 85°C.

Key Features

• Capacitance & Voltage: 3.9 mF nominal capacitance at a rated voltage of 350 V, ±20% tolerance (120 Hz, 20°C).
• Screw Terminal Mounting: Radial can with screw terminals (M5 nominal bolt for φ51 body) for secure, high-current connections and straightforward mechanical installation.
• High Ripple Current Capability: 14.8 A at 120 Hz (low frequency) and 20.72 A at 10 kHz (high frequency) to support demanding ripple conditions.
• Electrical Loss and Leakage: Tan δ of 0.25 (measured at 20°C, 120 Hz) and leakage current specified up to 3500 µA, with datasheet leakage formula 3√CV (µA) or 5 mA limit after 5 minutes at 20°C.
• Thermal and Life Ratings: Rated for operation from −40°C to +85°C with a load life of 2000 hours at 85°C under applied ripple current.
• Size & Packaging: Body dimensions approximately φ51 × 130L (L: 13 cm × D: 5.1 cm) in a radial can — shipped in cardboard packing for mass production supply.
• Regulatory: RoHS compliant per the datasheet specification.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in high-voltage DC supplies where 350 V and multi-millifarad capacitance are required.
• Equipment downsizing: Use in designs targeting reduced footprint while maintaining high capacitance and ripple handling, as noted in the LNY series guidance.
• High-ripple DC bus filtering: Suitable for DC bus and filter circuits that demand substantial low- and high-frequency ripple current capability.

Unique Advantages

• High-voltage, high-capacitance combination: 3.9 mF at 350 V provides significant bulk storage in a single component, reducing the need for parallel arrangements.
• Robust ripple performance: Specified ripple currents of 14.8 A (120 Hz) and 20.72 A (10 kHz) enable reliable operation under substantial AC stress.
• Extended operational life at elevated temperature: 2000-hour load life at 85°C supports long-term reliability in demanding thermal environments.
• Screw terminal mechanical reliability: M5-capable screw terminals and a radial can package offer durable electrical and mechanical connections for high-current applications.
• Wide operating temperature range: −40°C to +85°C supports deployment across varied operating environments.
