LNT2G123MSEJBB

The LNT2G123MSEJBB from Nichicon is a screw-terminal, radial aluminum electrolytic capacitor in the LNT series. It delivers 12,000 µF capacitance at a 400 V rating and is designed for general-purpose electronic designs that require high-capacitance energy storage and robust ripple handling.

Key value propositions include high ripple-current capability, a 5,000 hour endurance at 105°C, and a polarized screw-terminal package that supports secure high-current connections in demanding environments.

Key Features

• Capacitance and Tolerance — 12,000 µF nominal with tolerance of −20% to +20% at 120 Hz, 20°C, for predictable energy storage and filtering performance.
• Rated Voltage — 400 V DC rating suitable for high-voltage DC bus applications within general-purpose designs.
• Screw-Terminal Mounting — Radial can with screw terminals for secure bolted connections and straightforward installation in assemblies.
• High Ripple-Current Capability — Low-frequency ripple current 38.3 A at 120 Hz and high-frequency ripple current 53.62 A at 100 kHz to support heavy AC superposition and switching load conditions.
• Loss Characteristics — tanδ (loss tangent) 0.2 measured at 20°C, 120 Hz to characterize dissipation under typical test conditions.
• Leakage Current — Specified leakage current 5,000 µA (5 mA) after 5 minutes at rated voltage (20°C) for predictable standby loss behavior.
• Endurance and Temperature Range — 5,000 hour rated life at 105°C with operating temperature range −25°C to +105°C, supporting sustained operation in elevated ambient conditions.
• Mechanical Size & Packaging — Dimension φ90 × 220 mm (D: 90 mm, L: 220 mm); supplied in cardboard packing for bulk handling and protection during transport.
• Regulatory — RoHS compliant as specified for the LNT series.
• Polarized Design — Polar capacitor for correct polarity installations in DC energy storage and filtering circuits.

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy storage where 400 V rating and large capacitance reduce voltage ripple and support DC bus stability.
• High-ripple power systems — Circuits that present significant AC superposition benefit from the part’s high low- and high-frequency ripple-current ratings.
• Industrial electronic assemblies — Use in industrial converters and power modules requiring durable capacitors with a 5,000 hour life at 105°C.

Unique Advantages

• High energy density at elevated voltage — 12,000 µF at 400 V provides substantial bulk capacitance for compact high-voltage designs.
• Engineered for high ripple — Specified ripple currents (38.3 A at 120 Hz, 53.62 A at 100 kHz) enable reliable performance under heavy AC loading and switching environments.
• Robust thermal endurance — 5,000 hour life at 105°C supports long-term operation in hot enclosures and industrial ambient conditions.
• Secure screw-terminal connections — Bolted terminals simplify installation and ensure low-impedance, durable power connections for high-current circuits.
• Measured loss characteristics — tanδ = 0.2 (20°C, 120 Hz) gives a clear metric for dissipation and thermal planning.
• Regulatory compliance — RoHS compliance aids conformity to materials directives for supply-chain and regulatory requirements.
