LNX2H103MSEK

The LNX2H103MSEK is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple applications. It delivers 10,000 µF at 500 V with a screw-terminal mounting and is intended for general-purpose use in industrial power electronics.

Built to the Nichicon LNX series specifications, this part emphasizes high ripple capability, extended operational life at elevated temperature, and reliable screw-terminal connections for robust power-supply and inverter circuitry use.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance at a rated voltage of 500 V, with a tolerance of ±20% (at 120 Hz, 20°C).
• Screw-Terminal Mounting — Radial can with screw terminals designed for secure electrical and mechanical connection; nominal terminal bolt size for φ100 cases is M8.
• High Ripple Current — Rated ripple current of 23.8 A at 120 Hz and 33.32 A at 100 kHz, suitable for demanding ripple-handling in power circuits.
• Endurance at Elevated Temperature — Rated for 5,000 hours at +85°C when subjected to rated ripple conditions for 500 V parts.
• Operating Temperature Range — Specified for −25°C to +85°C operation.
• Low Leakage Current — After 5 minutes at rated voltage, leakage is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• Physical Size & Package — φ100 × 190 mm case (L: 19 cm × D: 10 cm) in a radial can with screw terminals, cardboard packing for mass production handling.
• Polarized — Electrolytic, polarized construction for DC power applications.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Industrial Power Supplies — Supports smoothing and energy storage for high-voltage power supplies used in industrial settings, including inverter circuitry.
• Inverter Circuits — Handles high ripple currents typical of inverter DC-link and filtering stages, leveraging the high ripple ratings and 500 V support.
• General Purpose High-Voltage Filtering — Provides bulk capacitance and ripple suppression in general-purpose high-voltage DC circuits where long life at elevated temperature is required.

Unique Advantages

• Extra-high Voltage Capability: 500 V rating enables use in higher-voltage DC systems where lower-voltage capacitors are unsuitable.
• High Ripple Endurance: Specified ripple current values at both 120 Hz and 100 kHz improve reliability in demanding power-conversion environments.
• Long Life at Elevated Temperature: Designed for 5,000 hours of operation at +85°C under rated ripple conditions for 500 V parts, supporting sustained performance in hot operating environments.
• Robust Mechanical Termination: Screw-terminal construction with M8 nominal bolt for φ100 case delivers secure electrical and mechanical connections for industrial assemblies.
• Large Capacitance in a Compact Can: 10,000 µF bulk capacitance in a φ100 × 190 mm package addresses DC-link and bulk energy storage needs without multipart solutions.
• Controlled Leakage Behavior: Leakage current specification (3√CV µA or 5 mA max after 5 minutes at 20°C) provides predictable standby and charged-state behavior for design validation.
