LNX2W153MSEKBN

The LNX2W153MSEKBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, rated at 15 mF (15,000 µF) and 450 V. It is a polarized, radial can device engineered for high-ripple, extra-high-voltage applications where long operational life and high current handling are required.

Designed for industrial power systems, the LNX2W153MSEKBN targets applications such as inverter circuitry and high-voltage power supplies, offering extended durability with a rated lifetime of 20,000 hours at +85°C and RoHS compliance.

Key Features

• Capacitance & Voltage: 15 mF (15,000 µF) nominal capacitance with a rated voltage of 450 V for bulk energy storage and high-voltage filtering.
• High Ripple Current Capability: Rated ripple current of 31.1 A at 120 Hz and 43.54 A at 100 kHz to support heavy AC ripple and switching currents.
• Long Life Endurance: Specified for 20,000 hours at +85°C under rated ripple conditions; endurance performance includes capacitance change within ±20% and controlled tan δ and leakage behavior after life test.
• Operating Temperature Range: -25°C to +85°C to match common industrial ambient conditions.
• Robust Mechanical & Electrical Termination: Screw terminal, radial can package (φ100 × 220L / L: 22 cm × D: 10 cm) for secure high-current connections and ease of installation.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA (whichever is smaller), supporting predictable DC behavior.
• Flame-Retardant Electrolyte & RoHS Compliant: Available with flame-retardant electrolyte options and compliant with RoHS directives (2011/65/EU,(EU)2015/863).
• Capacitance Tolerance: ±20% (typical tolerance at 120 Hz, 20°C) for design planning and margining.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for high-voltage power rails in industrial converters and power systems.
• Inverter Circuitry: DC link and ripple absorption in inverter stages where high ripple current and long life are required.
• High-Voltage Filtering: Filtering and decoupling in high-voltage DC circuits that demand stable capacitance over long operational periods.

Unique Advantages

• High Voltage Handling: 450 V rating enables use in extra-high-voltage power circuits without series stacking.
• Engineered for High Ripple: Significant ripple current ratings at both low and high frequencies reduce heating and extend service life in switching applications.
• Long-Term Reliability: 20,000-hour endurance at +85°C under rated ripple current supports extended maintenance intervals and predictable performance.
• Screw-Terminal Robustness: Screw terminals provide secure, low-resistance connections suitable for high-current installations and easier field maintenance.
• Regulatory and Safety Considerations: Flame-retardant electrolyte options and RoHS compliance address environmental and safety requirements.
