LNX2G182MSEFBN

The LNX2G182MSEFBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series designed for high-voltage, high-ripple applications. It provides 1.8 mF (1800 µF) capacitance at a 400 V rating in a robust radial can with screw terminals for secure electrical and mechanical connections.

Engineered for industrial power electronics, the part targets bulk smoothing and DC link duties where high ripple handling, long operational life, and reliable performance at elevated temperatures are required.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 400 V with ±20% tolerance, suitable for bulk energy storage and DC link applications.
• Screw Terminal Mounting — Radial can with screw terminals provides a secure, low-resistance connection for high-current bus wiring and easy field installation.
• High Ripple Current — Low-frequency ripple current of 6.0 A (120 Hz) and high-frequency ripple current of 8.4 A (100 kHz) to support heavy ripple loads in power converters.
• Long Endurance — Rated for 20,000 hours at +85°C under specified ripple conditions, offering extended operational life for continuous-duty industrial systems.
• Low Loss — Specified tan δ (DF) = 0.2 at 20°C, 120 Hz, supporting stable performance and manageable dissipation in filter and smoothing roles.
• Leakage Current — Low initial leakage current (2,540 µA), aiding in predictable DC behavior after voltage application.
• Operating Range & Size — Operates from −25°C to +85°C; package dimension φ51 × 110 mm (diameter × length) for compact high-capacity installations.
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing for standard mass-production handling.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and DC link support in inverter and converter systems where sustained ripple current and high voltage are required.
• Inverter Circuitry — Energy buffering and ripple attenuation for motor drive and variable-frequency drive front ends.
• High-Voltage Power Electronics — DC bus and filter applications that need 400 V rating combined with large capacitance and long endurance.

Unique Advantages

• High ripple capacity: The specified 6.0 A (120 Hz) and 8.4 A (100 kHz) ripple ratings allow handling of both low- and high-frequency ripple without compromising performance.
• Extended life at elevated temperature: 20,000-hour endurance at +85°C supports continuous-duty industrial deployments and reduces replacement frequency.
• Secure, serviceable connections: Screw-terminal construction provides mechanically robust, low-resistance terminations suitable for heavy-current bus wiring.
• Predictable electrical behavior: Low loss (tan δ = 0.2 at 20°C, 120 Hz) and specified leakage current enable predictable dissipation and DC performance during system design and testing.
• Compact high-voltage package: 1.8 mF in a φ51 × 110 mm can offers a balance of capacitance density and manageable footprint for power modules.
• Regulatory compliance: RoHS status ensures conformance to common environmental requirements for electronic assemblies.
