LNX2V103MSEHBN

The LNX2V103MSEHBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, specified at 10,000 µF and 350 V. It is designed for high-ripple, extra-high-voltage applications and is suited to industrial power systems such as inverter circuitry and power conversion equipment.

This capacitor provides high ripple-current handling and long operational life under rated ripple current at elevated temperature, offering designers a reliable bulk energy storage and smoothing component for high-voltage power electronics. The series is RoHS compliant and offers flame-retardant-electrolyte types.

Key Features

• Capacitance & Rated Voltage — 10,000 µF nominal capacitance with a 350 V rated voltage to support high-voltage DC link and smoothing applications.
• High Ripple Current — Rated ripple current of 21.8 A at 120 Hz and 30.52 A at 100 kHz, enabling effective filtering under heavy switching loads.
• Long Endurance — Specified for 20,000 hours of operation at +85°C when subjected to the rated ripple current, supporting extended service life in continuous-duty systems.
• Temperature Range & Low‑temperature Stability — Operating range from −25°C to +85°C with an impedance ratio Z(−25°C)/Z(+20°C) of 8, maintaining performance across typical industrial temperature swings.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is ≤ 3√CV (µA) or 5 mA, whichever is smaller (measurement condition at 20°C), enabling predictable standby and charged-state behavior.
• Mounting & Package — Screw-terminal radial can package for robust mechanical and electrical connections in high-current, serviceable power assemblies.
• Capacitance Tolerance — ±20% at 120 Hz, 20°C, providing clear expected variation for design margin calculations.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high-voltage industrial power supplies where sustained ripple handling and long life are required.
• Inverter DC Links — DC link capacitor for inverter circuitry, providing high ripple-current capability and voltage endurance for motor drives and power converters.
• High‑Voltage Power Conversion — Filtering and energy buffering in converters and rectifier stages that operate at elevated voltages and demand robust thermal endurance.

Unique Advantages

• Designed for high-ripple environments: Published ripple-current ratings at both 120 Hz and 100 kHz let engineers size capacitors for modern switching supplies and inverter systems.
• Extended operational life at elevated temperature: 20,000-hour endurance at +85°C under rated ripple current reduces maintenance frequency and supports continuous industrial operation.
• Predictable leakage behavior: Leakage current defined as ≤ 3√CV (µA) or 5 mA after 5 minutes enables accurate power-loss and safety margin calculations.
• Robust mechanical termination: Screw-terminal radial can package provides secure connections for high-current buswork and simplifies replacement or servicing.
• Series-level compliance and options: LNX series offers extra-high voltage range and flame‑retardant electrolyte types, supporting safety-focused designs and RoHS compliance.
