LNK2V123MSEJBB

The LNK2V123MSEJBB is a screw‑terminal aluminum electrolytic capacitor designed for general-purpose applications requiring high bulk capacitance at elevated DC voltages. It delivers 12,000 µF at a rated voltage of 350 V in a robust radial can with screw terminals for secure electrical and mechanical connections.

Engineered for continuous operation up to 85°C with a 5,000‑hour endurance rating, this Nichicon LNK series capacitor is intended for designers who need stable capacitance, defined leakage characteristics, and high ripple current capability in mass‑production quantities.

Key Features

• High Capacitance: 12,000 µF nominal capacitance for substantial bulk energy storage in a single radial can.
• 350 V Rated Voltage: Rated for 350 V operation to support higher‑voltage DC systems.
• Screw Terminal Mounting: Radial can with screw terminals (M5 nominal bolt for φ90 size) for reliable connection and easy installation.
• Operating Temperature Range: −25°C to +85°C, suitable for applications within this temperature band.
• Long Endurance: Load life 5,000 hours at 85°C with specified DC bias plus rated ripple current; capacitance change within ±20% after the endurance test.
• Defined Loss and Leakage: Tangent of loss angle (tan δ) 0.2 and leakage current specified at 5,000 µA.
• High Ripple Current Capability: Ripple current ratings of 28.4 A at 120 Hz and 39.76 A at 10 kHz, enabling substantial AC current handling at typical frequencies.
• Electrical Safety Characteristics: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2,500 V for 1 minute with no abnormality.
• Packaging and Production: Cardboard packing and designated for mass production.
• RoHS Compliant: Meets RoHS requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power systems: Suited for circuits that require large bulk capacitance at up to 350 V in a screw‑terminal package.
• Industrial equipment: Useful where secure, bolted terminal connections and long endurance at elevated temperature are required.
• High‑voltage DC subsystems: Applicable to general-purpose DC systems needing defined leakage and insulation characteristics at 350 V.

Unique Advantages

• High stored energy in a single part: 12,000 µF at 350 V reduces the need for multiple capacitors to achieve required bulk capacitance.
• Robust mechanical connection: Screw‑terminal construction provides reliable, serviceable connections for installations and maintenance.
• Validated endurance: 5,000‑hour life at 85°C with specified post‑test capacitance retention gives predictable long‑term performance.
• Clear electrical limits: Specified leakage current, tan δ, insulation resistance and voltage‑proof values allow straightforward design verification.
• High ripple tolerance: Significant ripple current ratings at 120 Hz and 10 kHz enable use in applications with substantial AC components.
• Regulatory compliance: RoHS‑compliant construction supports environmental and regulatory requirements.
