LNX2W103MSEJBN

The LNX2W103MSEJBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNX series, specified for extra-high-voltage, high-ripple applications. It pairs a 10,000 µF capacitance with a 450 V rating and is optimized for industrial power supplies and inverter circuitry.

Designed for sustained ripple duty, this part offers long operational life and high reliability under demanding DC-link and power-filtering conditions, with RoHS compliance and flame-retardant electrolyte available by type.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance with a rated voltage of 450 V; capacitance tolerance ±20% at 120 Hz, 20°C.
• High Ripple Performance — Standard ripple current ratings of 23 A at 120 Hz and 32.2 A at 100 kHz support heavy AC ripple and switching loads.
• Long Life & Endurance — Rated for 20,000 hours at +85°C under rated ripple current (endurance conditions per series specification).
• Operating Temperature Range — Specified for use from −25°C to +85°C to cover a wide range of industrial environments.
• Package & Mounting — Screw terminal radial can package for secure high-current connections; physical size listed as L: 19 × D: 9 cm with a maximum seated height of 7.48 inch.
• 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 DC behavior.
• Safety & Compliance — RoHS compliant (2011/65/EU, (EU)2015/863); flame-retardant electrolyte available by type for enhanced safety options.

Typical Applications

• Industrial power supplies — DC-link and bulk filtering in high-voltage industrial power supplies, especially where inverter circuitry imposes substantial ripple currents.
• Inverter circuitry — Energy storage and smoothing for inverter stages that require extra-high voltage capability and sustained ripple performance.
• High-voltage DC filtering — Bulk capacitance and ripple absorption in extra-high-voltage applications demanding both high capacitance and long life.

Unique Advantages

• High ripple-handling capability: Engineered ripple ratings (23 A @120 Hz, 32.2 A @100 kHz) reduce thermal stress for switching power and inverter applications.
• Extended operational life: 20,000-hour endurance at +85°C under rated ripple current supports long-term, continuous operation in industrial systems.
• Extra-high voltage support: 450 V rating (series available across 350–550 V) enables use in demanding DC-link and high-voltage filter designs.
• Robust mechanical termination: Screw-terminal radial can package provides reliable high-current connections and simplifies installation in power assemblies.
• Predictable leakage behavior: Leakage current limits defined by 3√(C·V) µA or 5 mA (whichever is smaller) aid in system-level leakage budgeting and safety analysis.
• Regulatory and safety options: RoHS compliance and an available flame-retardant electrolyte provide environmental conformity and improved safety selection.
