The LNX2V392MSEH is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage, high‑ripple industrial power applications. It provides 3900 µF capacitance at a 350 V rating in a radial can with screw terminals for secure, serviceable connections.

Engineered for inverter circuitry and industrial power supplies, this part emphasizes high ripple handling, long operational life at elevated temperature, and RoHS‑compliant materials for reliable, long‑term power smoothing and energy storage.

Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) rated at 350 V to support high‑voltage filtering and bulk energy storage.
• High Ripple Current: Rated ripple currents of 10.3 A at 120 Hz and 14.42 A at 100 kHz enable robust handling of switching and inverter loads.
• Long Life / Reliability: Designed for 20,000 hours of operation at +85°C under rated ripple current, providing extended service life in demanding environments.
• Temperature Range: Operates from −25 °C to +85 °C, suitable for typical industrial ambient conditions.
• Mounting & Package: Screw terminal radial can package for secure connections and easy replacement; physical dimensions: length 9.0 cm × diameter 7.62 cm, seated height max 3.543 in.
• Materials & Compliance: Flame‑retardant electrolyte options are available and the product is RoHS compliant (2011/65/EU, (EU)2015/863).
• Capacitance Tolerance & Leakage: Capacitance tolerance ±20% and leakage current after 5 minutes limited per datasheet formula (3√CV μA or 5 mA, whichever is smaller) for predictable behavior.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy buffering in power supplies for industrial controls and systems, including inverter front ends.
• Inverter & Motor Drive Systems: DC link and smoothing capacitor for inverter circuitry where high ripple current and high voltage are required.
• High‑Voltage Power Electronics: Energy storage and filtering in converters and power modules operating at elevated voltages and demanding ripple conditions.

Unique Advantages

• High ripple endurance: Specified ripple current ratings and 20,000‑hour life at +85 °C under rated ripple current reduce the need for frequent replacement in continuous‑duty applications.
• Secure, serviceable connections: Screw terminal construction simplifies installation, inspection, and replacement in field service environments.
• Predictable electrical behavior: Defined leakage current limits and ±20% capacitance tolerance support reliable design margins and predictable performance.
• Industrial temperature suitability: −25 °C to +85 °C operating range fits common industrial enclosures and equipment ambient conditions.
• Regulatory compliance: RoHS compliance and availability of flame‑retardant electrolyte options support regulatory and safety considerations.
