LNX2G182MSEF

The LNX2G182MSEF is an aluminum electrolytic capacitor in Nichicon’s LNX series designed for screw-terminal mounting. With a 1.8 mF (1800 µF) capacitance at a 400 V rating and a long endurance specification, it targets high-voltage power applications that require sustained ripple handling and long operational life.

Typical use cases include industrial power supplies and inverter circuitry where high ripple currents, high voltage capability, and long-life operation are required. The part is RoHS compliant and offered in a radial can with screw terminals for secure high-current connections.

Key Features

• Capacitance and Voltage: 1.8 mF (1800 µF) nominal capacitance rated for 400 V DC, suitable for extra-high-voltage power circuits.
• Long Endurance: Rated for 20,000 hours at +85°C under rated ripple current when used within specified conditions (LNX series endurance).
• High Ripple Current Capability: Rated ripple current of 6 A at 120 Hz and 8.4 A at 100 kHz, enabling sustained ripple handling in power converters.
• Screw-Terminal Mounting: Radial can with screw terminals for robust, low-resistance connections in high-current and high-voltage installations.
• Operating Temperature: Specified operating range from −25°C to +85°C for typical industrial environments.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (per LNX series datasheet formula).
• Tolerance and Polarity: Capacitance tolerance ±20% and polarized construction—observe correct polarity in application.
• Form Factor: Size approximately φ51 × 110 mm (L), radial can with screw terminals for secure mechanical mounting.
• RoHS Compliance: Compliant with RoHS requirements as indicated for the LNX series.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in industrial PSU designs, including inverter front-ends where high-voltage, high-ripple handling is required.
• Inverter and Converter Modules: Energy buffering and ripple absorption in inverter and DC–DC converter circuitry operating at elevated voltages.
• High-Voltage Power Systems: Filtering and decoupling in systems that need extra-high-voltage capacitors with extended operational life.
• General Purpose Power Filtering: Applications requiring polarized aluminum electrolytic capacitors with screw-terminal connections for reliable, serviceable power connections.

Unique Advantages

• Extended Service Life: 20,000 hours endurance at +85°C under rated ripple current delivers predictable long-term performance in continuous-duty applications.
• High Ripple Handling: Specified ripple current values at both low and high frequencies reduce thermal stress and support reliable operation in switching power applications.
• Secure, High-Current Termination: Screw-terminal radial can construction provides mechanically robust, low-resistance connections suitable for industrial installations.
• Extra-High Voltage Capability: 400 V rating enables use in elevated-voltage power stages and energy storage roles where lower-voltage capacitors are not suitable.
• Measured Leakage Limits: Leakage current bounded by the 3√(C·V) µA or 5 mA rule offers predictable post-assembly behavior for system power-up and safety considerations.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products where restricted substances regulations apply.
