LNX2W182MSEFBB

The LNX2W182MSEFBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple power applications. With a rated capacitance of 1800 µF at 450 V and a long endurance specification, it targets industrial power electronics where robust bulk capacitance and reliable connections are required.

Its screw-terminal package and series-level design focus make it suitable for industrial power supplies and inverter circuitry, delivering extended life under rated ripple conditions.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance at a 450 V rated voltage for high-voltage energy storage and filtering.
• Long Endurance — Specified for 20,000 hours at +85°C under rated ripple current, supporting extended service life in continuous-duty power systems.
• High Ripple Capability — Rated ripple currents of 6.4 A at 120 Hz and 8.96 A at 100 kHz, enabling handling of substantial AC stress in power-conversion circuits.
• Robust Mounting — Screw terminal, radial can package for secure, low-resistance connections in larger power assemblies; recommended terminal bolt (nominal) for φ51 size is M5.
• Operating Range & Tolerance — Operating temperature −25°C to +85°C with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is ≤ 3√(C·V) μA or 5 mA, whichever is smaller (at 20°C), providing predictable leakage behavior for design calculations.
• Compliance — RoHS compliant.
• Size & Packaging — Physical size φ51 × 130 mm length (L:13 cm × D:5.1 cm) and supplied in cardboard packing for production volumes.

Typical Applications

• Industrial power supplies & inverter circuitry — Provides high-voltage bulk capacitance and high ripple tolerance required in inverter front-ends and industrial converters.
• High-voltage power filtering — 450 V rating and 1800 µF capacitance make it suitable for smoothing and energy buffering in high-voltage power stages.
• General-purpose power electronics — Screw-terminal mounting and long life suit larger systems requiring robust connections and extended operational reliability.

Unique Advantages

• Designed for extended duty: 20,000-hour endurance at 85°C under rated ripple current reduces replacement frequency in continuous-operation equipment.
• High ripple handling: Explicit ripple current ratings at both 120 Hz and 100 kHz allow designers to size capacitors against measured ripple across a range of switching frequencies.
• Secure electrical connection: Screw-terminal radial can simplifies assembly and provides low-resistance, mechanical stability for high-current bus connections.
• Predictable leakage behavior: Clear leakage current limit (≤ 3√CV μA or 5 mA after 5 minutes) supports accurate thermal and power-loss calculations.
• High-voltage capability: 450 V rating supports use in higher-voltage power-conversion topologies without stacking multiple components.
• Regulatory compliance: RoHS compliance aligns the component with common environmental requirements for commercial and industrial products.
