LNX2W153MSEK

The LNX2W153MSEK from Nichicon is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple industrial power applications. It delivers 15,000 µF capacitance at a 450 V rating with a long operational life and robust mounting suitable for inverter circuitry and heavy-duty power supplies.

Engineered for sustained performance at elevated temperatures, this polarized capacitor is targeted at designs that require large energy storage, high ripple handling and proven long-life endurance in demanding environments.

Key Features

• High Capacitance & Voltage — 15,000 µF (15 mF) nominal capacitance at a 450 V rated voltage for bulk energy storage and DC link applications.
• Long Life Endurance — Rated for 20,000 hours at +85°C under standard ripple current conditions, supporting extended service life in continuous-duty systems.
• High Ripple Current Capability — Rated ripple current of 31.1 A at 120 Hz and 43.54 A at 100 kHz to handle heavy AC and switching ripple in power converters.
• Robust Screw-Terminal Mounting — Radial can with screw terminals (M8 nominal bolt for φ100 size) for secure electrical and mechanical connections in industrial assemblies.
• Wide Operating Temperature — Specified operating range from -25°C to +85°C to cover typical industrial ambient conditions.
• Leakage Current Specification — Leakage after 5 minutes is limited to 3√CV (µA) or 5 mA, whichever is smaller, per the datasheet measurement condition.
• Polarized Design & Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• RoHS Compliant — Meets RoHS directive requirements as stated in the product information.

Typical Applications

• Industrial Power Supplies — Used as bulk storage and smoothing capacitors in industrial supplies where high voltage and long life are required, including inverter circuitry.
• Power Converters and Inverters — Suited for DC link and energy buffer roles in power electronics thanks to high capacitance and elevated ripple current ratings.
• Motor Drives and Industrial Drives — Provides stable energy storage and ripple handling for drive systems and other heavy-duty control equipment.

Unique Advantages

• Large Energy Density at High Voltage — 15,000 µF at 450 V offers substantial stored energy for DC link and smoothing duties without series stacking.
• Designed for Continuous Heavy Use — 20,000-hour endurance at 85°C under rated ripple conditions supports prolonged operation in demanding applications.
• Superior Ripple Handling — High ripple ratings at both low (120 Hz) and high (100 kHz) frequencies reduce thermal stress and support switching power stages.
• Mechanically Secure Termination — Screw-terminal radial can construction simplifies robust connections in high-current industrial layouts.
• Temperature Range for Industrial Environments — Operational from −25°C to +85°C to accommodate a wide range of ambient conditions encountered in industrial equipment.
