LNY2G183MSEJ

The LNY2G183MSEJ is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for high-capacitance, high-voltage applications. With 18,000 µF at 400 V and a compact φ90×230 L form factor, it targets general-purpose power systems where high ripple handling and reliable bulk energy storage are required.

Key value propositions include a high rated capacitance and voltage, robust ripple-current capability at both low and high frequencies, and a 2000-hour load life at 85°C for dependable performance in demanding thermal environments.

Key Features

• High Capacitance & Voltage: 18,000 µF nominal capacitance rated at 400 V for substantial bulk energy storage in power systems.
• Screw Terminal Mounting: Radial can with screw terminals enabling secure, low-resistance connections for high-current applications.
• Wide Operating Temperature: Specified for –40°C to +85°C to support use across varied ambient conditions.
• High Ripple Current Capability: 30.6 A at 120 Hz (low frequency) and 42.84 A at 10 kHz (high frequency) to handle significant AC ripple in power conversion and filtering roles.
• Endurance and Reliability: 2000 hours load life at 85°C under rated ripple current, with leakage current specified up to 5000 µA.
• Loss Tangent: tanδ of 0.25 (reference), providing a measurable dissipation characteristic for thermal and ripple considerations.
• Regulatory Compliance: RoHS compliant construction.
• Packaging & Availability: Cardboard packing and mass-production status for demand-volume procurement.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in high-voltage power assemblies that require large capacitance and strong ripple handling.
• Power conversion and filtering: Use where high low- and high-frequency ripple currents must be absorbed reliably over extended operating periods.
• Equipment downsizing efforts: High capacitance in a screw-terminal can supports designs aiming to reduce overall system footprint while maintaining energy storage.

Unique Advantages

• Large energy reservoir: 18,000 µF at 400 V supplies substantial stored energy for smoothing, hold-up, and transient suppression needs.
• Robust ripple handling: Rated ripple currents of 30.6 A (120 Hz) and 42.84 A (10 kHz) reduce stress on circuit components and improve thermal stability under AC loading.
• Secure electrical connections: Screw-terminal design minimizes connection resistance and supports repeated installation and maintenance.
• Proven endurance: 2000-hour life at 85°C with rated ripple current offers predictable long-term behavior under high-temperature operating profiles.
• Design-ready specification: Clear, measurable parameters—leakage current (up to 5000 µA), tanδ (0.25), and polarization—simplify thermal and electrical margin calculations.
• Regulatory alignment: RoHS compliance supports environmentally constrained product designs.
