LNK2G123MSEJ

The LNK2G123MSEJ is a 12,000 µF, 400 V aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It is part of Nichicon’s LNK series and combines high capacitance and high-voltage rating with a screw-terminal mounting style for secure electrical and mechanical connections.

Engineered for long service life and high ripple-handling capability, this capacitor addresses bulk energy storage and smoothing needs in systems that require a robust 400 V capacitor with a wide operating temperature range and verified endurance.

Key Features

• Capacitance & Voltage — 12,000 µF (12 mF) rated at 400 V provides substantial bulk energy storage for high-voltage power circuits.
• Tolerance & Loss — Capacitance tolerance ±20% (at 120 Hz, 20°C) with tangent of loss angle (tan δ) specified at 0.2 for predictable AC performance.
• Long Endurance — Rated life of 5,000 hours at 85°C under DC bias plus rated ripple current; endurance specification: capacitance change within ±20% after the test.
• High Ripple Current Capability — Ripple current ratings of 28.5 A at 120 Hz and 39.9 A at 10 kHz to support demanding AC ripple environments.
• Temperature Performance — Operating temperature range −25°C to +85°C with an impedance ratio Z(−25°C)/Z(+20°C) ≤ 8 (measured at 120 Hz), supporting low-temperature stability.
• Electrical Integrity — Leakage current after 5 minutes at rated voltage is limited to 3√(C·V) µA or 5 mA, whichever is smaller; insulation resistance >100 MΩ at DC 500 V; voltage proof: AC 2500 V for 1 minute between terminal and bracket.
• Package & Mounting — Radial can with screw terminals, physical size φ90 × 155 L (L: 15.5 cm × D: 9.0 cm), designed for secure bolted connections in heavy-duty assemblies.
• Compliance — RoHS compliant.

Typical Applications

• General-purpose high-voltage power systems — Provides bulk smoothing and energy storage where a 12,000 µF, 400 V screw-terminal capacitor is required.
• Industrial power electronics — Used in power supply filter stages and DC link networks that demand high capacitance and verified endurance at 85°C.
• High-ripple environments — Suitable for applications that require significant ripple-current handling (specified at 120 Hz and 10 kHz).

Unique Advantages

• High-voltage, high-capacitance combination: 12,000 µF at 400 V delivers substantial stored energy per component for compact power designs.
• Verified long life: 5,000-hour endurance at 85°C under rated conditions gives clear, test-based expectations for longevity in hot operating environments.
• Strong ripple-handling: Rated ripple currents of 28.5 A (120 Hz) and 39.9 A (10 kHz) support demanding switching or rectified-power applications.
• Robust electrical safeguards: Defined leakage-current limits, insulation resistance >100 MΩ at DC 500 V, and voltage-proof testing (AC 2500 V, 1 minute) provide measurable electrical reliability.
• Screw-terminal mounting: Enables secure, low-resistance connections for high-current and heavy-duty assemblies.
• RoHS compliant: Meets regulatory restrictions for hazardous substances.
