LNY2V183MSEJ

The LNY2V183MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering 18,000 µF capacitance at a 350 V rating in a φ90 × 155 mm can. Designed for general-purpose high-voltage applications, it is suited for equipment downsizing where high capacitance and robust power-handling characteristics are required.

Key value propositions include high capacitance in a screw-terminal package, rated operation from −40 °C to 85 °C, and a specified load life under ripple conditions (2000 hours at 85 °C).

Key Features

• High Capacitance: 18,000 µF rated capacitance (±20% at 120 Hz, 20 °C) for substantial bulk energy storage and filtering.
• High Voltage Rating: 350 V rated voltage to support high-voltage circuits and systems.
• Screw-Terminal Package: Radial can with screw terminals and M5 bolt nominal diameter for secure, low-impedance connections in assemblies.
• Operating Temperature Range: Specified for −40 °C to +85 °C, enabling use across a broad range of ambient conditions.
• Load Life Endurance: Rated for 2000 hours when subjected to rated ripple current at 85 °C, with defined post-test limits for capacitance change, tan δ, and leakage current.
• High Ripple Current Capability: 31.1 A at 120 Hz and 43.54 A at 10 kHz, supporting demanding AC ripple environments.
• Leakage and Insulation Performance: Leakage current specified as not more than 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at 20 °C; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Safety and Voltage Withstand: No abnormality at AC 2500 V for 1 minute between terminal and bracket.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose high-voltage equipment: Provides bulk energy storage and smoothing in designs that require 18,000 µF at 350 V.
• Space-constrained power assemblies: Suited for equipment downsizing where a high-capacitance, screw-terminal can reduces overall system footprint.
• High-ripple current modules: Used where significant ripple current capability is needed, with specified ripple ratings at 120 Hz and 10 kHz.

Unique Advantages

• Large capacitance in a compact screw-terminal can: 18,000 µF at 350 V delivers substantial stored energy while supporting radial screw-terminal mounting for secure installation.
• Designed for sustained ripple stress: Specified ripple current ratings and a 2000-hour load life at 85 °C provide predictable behavior under continuous ripple conditions.
• Wide operating temperature: −40 °C to +85 °C rating makes the part suitable for a range of ambient environments without derating the basic specs provided.
• Clear electrical limits and reliability metrics: Defined leakage current, insulation resistance, and voltage-proof characteristics support engineering validation and system-level reliability planning.
• RoHS compliance: Facilitates integration into products targeting restricted-substance requirements.
