LNY2V392MSEGBB

The LNY2V392MSEGBB from Nichicon is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers 3.9 mF (3900 μF) capacitance at a 350 V rating with a robust screw-terminal package and high ripple handling for demanding power circuits.

Built for reliability in compact equipment, this LNY series part supports a wide operating temperature range and a rated load life of 2000 hours at 85°C, making it suitable where high-capacitance, high-voltage bulk energy storage and smoothing are required.

Key Features

• High Capacitance and Voltage — 3.9 mF (3900 μF) rated at 350 V for bulk energy storage and smoothing in high-voltage circuits.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, high-current connections and simple field wiring or bracket mounting.
• Load Life and Endurance — Rated for 2000 hours at 85°C under rated ripple current, supporting sustained operation at elevated temperatures.
• Wide Temperature Range — Operates from −40°C to +85°C to accommodate a broad set of environmental conditions.
• High Ripple Current Capability — 14.1 A at 120 Hz and 19.74 A at 10 kHz, enabling effective AC ripple handling across low- and high-frequency domains.
• Leakage and Insulation Characteristics — Leakage current after 5 minutes meets the datasheet limit of not more than 3√(C·V) μA or 5 mA (whichever is smaller); insulation resistance is more than 100 MΩ at DC 500 V between terminal and bracket.
• Safety/Maintenance Features — Voltage proof tested to AC 2500 V for 1 minute between terminal and bracket; sleeve marked in white on black for easy identification.
• Compact, Mechanically Specified Form — φ63.5 × 80 L package with M5 bolt nominal terminal diameter and radial can footprint for bracket mounting; height seated max 3.15 inch.
• RoHS Compliant — Meets RoHS directive requirements for lead-free assembly.

Typical Applications

• General-Purpose Power Systems — Bulk filtering and smoothing for power supplies where high-capacitance, high-voltage storage is required.
• Industrial Power Electronics — DC link or energy storage in equipment that benefits from screw-terminal mounting and elevated ripple current capability.
• Equipment Downsizing — The LNY series is described as suited for equipment downsizing, providing higher capacitance in a compact screw-terminal can.

Unique Advantages

• High voltage and capacitance in a single part: 350 V rating with 3.9 mF (3900 μF) reduces the need for parallel components to reach required energy storage.
• Robust electrical performance: Specified ripple currents at 120 Hz and 10 kHz support both low- and high-frequency ripple handling in power conversion systems.
• Durability at elevated temperature: 2000-hour rated life at 85°C provides predictable endurance for continuous operation in warm environments.
• Secure mechanical and electrical connections: Screw terminals and M5 nominal bolt diameter enable reliable mounting and high-current terminations.
• Tested insulation and voltage proof: Insulation resistance >100 MΩ (DC 500 V) and AC 2500 V/1 minute voltage proof between terminal and bracket enhance safety margins.
• RoHS compliance: Facilitates use in lead-free manufacturing and regulatory-compliant assemblies.
