LNX2V123MSEHBB

The LNX2V123MSEHBB is a screw-terminal, aluminum electrolytic capacitor from Nichicon’s LNX series, offering 12,000 µF capacitance at a 350 V rating. It is a polarized radial can with screw terminals designed for heavy-duty power applications.

Targeted for industrial power supplies and inverter circuitry, this part delivers high ripple-current capability and long operational life, providing reliable bulk energy storage and smoothing in extra-high-voltage power systems. The capacitor is RoHS compliant and offers a flame-retardant electrolyte option.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance rated at 350 V with ±20% tolerance (specified at 120 Hz, 20°C), suitable for high-capacitance DC link and bulk storage applications.
• High Ripple Current — Rated ripple current of 25.1 A at 120 Hz and 35.14 A at 100 kHz, enabling robust filtering and smoothing under heavy AC ripple conditions.
• Long Life & Endurance — Designed for long-term operation with 20,000 hours endurance at +85°C when operated at the rated ripple current, supporting reduced maintenance and extended service intervals.
• Operating Temperature Range — Specified for operation from −25°C to +85°C to fit industrial ambient environments.
• Mechanical & Mounting — Screw terminal radial can package for secure electrical connections and straightforward installation; physical size noted as L: 19 cm × D: 7.62 cm with a maximum seated height of 7.48 in.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to ≤ 3√CV (µA) or 5 mA, whichever is smaller (measurement at 20°C), supporting stable DC performance.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863); flame-retardant electrolyte option available per series documentation.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in industrial power supplies where sustained ripple handling and long life are required.
• Inverter Circuitry — DC link and filtering applications in inverter systems that demand high ripple current capability and extra-high-voltage tolerance.
• High-Voltage Power Electronics — Energy storage and decoupling in power electronic systems operating at or near the 350 V range.
• General-Purpose Power Filtering — Polarized high-capacitance filtering for equipment requiring robust bulk capacitance and secure screw-terminal connections.

Unique Advantages

• High ripple-current capability: Rated ripple currents (25.1 A at 120 Hz, 35.14 A at 100 kHz) support demanding filtering duties and reduce thermal stress in heavy-load designs.
• Extended operational life: 20,000 hours at +85°C under rated ripple current lowers lifecycle costs and installation downtime.
• Secure screw-terminal mounting: Robust mechanical connection simplifies installation and serviceability in industrial assemblies.
• Large capacitance at high voltage: 12,000 µF at 350 V provides substantial bulk energy storage for DC link and smoothing applications.
• Regulatory and safety options: RoHS compliance and available flame-retardant electrolyte help meet environmental requirements and enhance safety options.
