LNX2W182MSEG

The LNX2W182MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series designed for high-voltage, high-ripple industrial power applications. It delivers 1800 µF capacitance at a 450 V rating in a rugged radial can with screw terminals for secure panel or bus-bar connections.

Engineered for inverter and industrial power-supply use, the device combines high ripple-current capability and extended endurance for reliable DC‑link, smoothing and filtering duties in demanding environments.

Key Features

• Capacitance & Tolerance — 1.8 mF (1800 µF) nominal with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — 450 V rated voltage suitable for extra-high-voltage power-supply sections.
• High Ripple-Current Capability — 6.10 A at 120 Hz (low frequency) and 8.54 A at 100 kHz (high frequency) to support heavy ripple and switching loads.
• Long Endurance — Designed for 20,000 hours of life at +85°C under rated ripple-current conditions.
• Measured Loss & Leakage — Dissipation factor tanδ = 0.2 (measured at 20°C, 120 Hz) and leakage current specified at 2700 µA.
• Screw-Terminal Radial Can — Robust screw-terminal package with nominal M5 bolt for the φ63.5 body, enabling secure mechanical and electrical connections.
• Operating Environment — Rated for -25°C to +85°C operation and supplied in cardboard packing; RoHS compliant.

Typical Applications

• Industrial Power Supplies — DC‑link smoothing and bulk energy storage in industrial AC/DC and DC/DC converter stages.
• Inverter Circuitry — Filtering and ripple absorption for inverter power stages where high voltage and sustained ripple are present.
• General Purpose Power Filtering — Bulk capacitance for high-voltage power rails in general-purpose industrial equipment.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 6.10 A (120 Hz) and 8.54 A (100 kHz) reduce heating and extend service life in switching environments.
• Extra-high voltage capability: 450 V rating allows use in higher-voltage DC bus and power-conversion topologies.
• Extended operational life: 20,000 hours at 85°C under rated ripple conditions provides predictable long-term performance for industrial systems.
• Screw-terminal reliability: Radial can with screw terminals and M5 nominal bolt offers secure mounting and low-impedance connection for heavy-current installations.
• Measured electrical stability: Specified tanδ and leakage current figures (0.2 and 2700 µA) enable straightforward thermal and leakage budgeting in designs.
• RoHS compliant and production-ready: Series-level RoHS compliance and mass-production status support volume supply and environmental requirements.
