LNX2V123MSEH

The LNX2V123MSEH is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNX series, designed for high‑ripple, extra‑high‑voltage power applications. It provides 12,000 µF capacitance at a 350 V rating in a radial can with screw terminals for secure, high‑current connections.

Engineered for industrial power supplies and inverter circuitry, this module delivers long operational life and high ripple handling for DC‑link and power‑smoothing duties in demanding systems.

Key Features

• Capacitance & Voltage: 12,000 µF rated capacitance at 350 V for bulk energy storage and DC‑link applications.
• High Ripple Capability: Supports 25.1 A ripple at 120 Hz (low frequency) and 35.14 A at 100 kHz (high frequency), enabling effective smoothing under heavy ripple conditions.
• Long Life & Endurance: Rated for 20,000 hours at +85°C under specified ripple current, supporting extended service in continuous‑operation environments.
• Loss Tangent (tan δ): tanδ = 0.2 (measured at 20°C, 120 Hz), providing a quantified dissipation characteristic for thermal and loss calculations.
• Leakage Current: Specified ≤ 5,000 µA (measured after rated voltage application), giving a defined bound for insulation/leakage budgeting.
• Robust Mechanical Package: Radial can with screw terminals (φ76.2 × 190 mm length) for secure bolted connections and straightforward mounting.
• Operating Temperature Range: −25°C to +85°C, matching the endurance rating and typical industrial thermal environments.
• Regulatory: RoHS compliant.
• Packaging & Availability: Supplied in cardboard packing; status: mass production.

Typical Applications

• Industrial Power Supplies: DC‑link and bulk smoothing in inverter and converter power stages where sustained ripple handling and high voltage are required.
• Inverter Circuitry: Energy buffering and ripple absorption in inverter systems that demand high ripple current endurance at elevated voltages.
• Power Electronics Modules: Filtering and decoupling in large‑format power assemblies and rectifier stacks where secure screw‑terminal connections are preferred.
• General‑Purpose High‑Voltage Power Design: Applications requiring polarized aluminum electrolytic bulk capacitance with clear life and leakage specifications.

Unique Advantages

• High Ripple Endurance: Measured ripple ratings at both low and high frequencies provide designers with verifiable parameters for thermal and lifetime planning.
• Long Operational Life: 20,000‑hour endurance at 85°C under rated ripple current supports continuous industrial operation and reduces replacement frequency.
• Screw‑Terminal Reliability: Boltable screw terminals enable low‑resistance, mechanically robust connections suitable for high‑current systems.
• Defined Loss and Leakage Metrics: Specified tanδ and leakage current figures allow accurate loss, heating and leakage budgeting in system designs.
• Clear Mechanical Footprint: φ76.2 × 190 mm can size and radial package simplify mechanical integration and bracket selection for mounting.
• Regulatory Compliance: RoHS compliance supports use in products requiring lead‑free supply chain adherence.
