LNT2G123MSEJ

The LNT2G123MSEJ is a screw-terminal aluminum electrolytic capacitor designed for high-voltage, high-capacitance applications. With a 400 V rated voltage and 12,000 µF capacitance, this radial can-style capacitor provides bulk energy storage and high ripple-current handling in industrial and power-electronics systems.

Engineered for robust operation up to +105°C and a 5,000 hour endurance at rated ripple current, the LNT2G123MSEJ is targeted at general-purpose power filtering, DC link smoothing and other demanding high-voltage applications where long life and reliable terminal connections are required.

Key Features

• High capacitance: 12,000 µF nominal capacitance (±20%) provides substantial bulk energy storage for smoothing and decoupling.
• 400 V rated voltage: Designed for high-voltage DC applications requiring a 400 V rating.
• Screw terminal mounting: Radial can with screw terminals offers secure, low-resistance connections and easy mechanical mounting for high-current bus implementations.
• High ripple-current capability: 38.3 A at 120 Hz (low frequency) and 53.62 A at 100 kHz (high frequency) to support heavy AC ripple and switching currents.
• Endurance at elevated temperature: 5,000 hours life at +105°C under rated ripple current, delivering predictable long-term performance in hot environments.
• Operating temperature range: Rated for –25°C to +105°C for the 160–500 V class, supporting a wide range of ambient conditions.
• Loss and leakage characteristics: Specified tan δ of 0.2 and leakage current listed at 5,000 µA to help predict dissipation and standby loss.
• Form factor and packaging: Large φ90 × 220 mm can size for high-capacitance needs; supplied in cardboard packing and available in mass production quantities.
• RoHS compliant: Meets the RoHS directive as stated in the product documentation.

Typical Applications

• High-voltage power supplies: Bulk smoothing and energy storage where 400 V rating and large capacitance are required to stabilize DC rails.
• DC link and inverter systems: DC link filtering for converters and inverters that demand high ripple-current capability and durable screw-terminal connections.
• Industrial power electronics: Energy buffering and ripple suppression in motor drives, power conditioners, and other industrial equipment operating at elevated temperatures.

Unique Advantages

• Substantial energy capacity: 12,000 µF provides significant bulk capacitance to reduce voltage ripple and support transient loads.
• High ripple handling: Rated ripple currents of 38.3 A (120 Hz) and 53.62 A (100 kHz) enable reliable operation with heavy AC and switching currents.
