LNT2W123MSEJBN

The LNT2W123MSEJBN is an aluminum electrolytic capacitor in a screw-terminal radial can package designed for general-purpose high-voltage applications. It delivers 12,000 µF of capacitance at a 450 V rating with continuous operation up to 105°C.

This part is optimized for designs that require substantial bulk capacitance, high ripple-current handling and long-term endurance: it is specified for high ripple current at both low and high frequencies and a rated lifetime of 5,000 hours at 105°C.

Key Features

• High Capacitance and Voltage: 12,000 µF nominal capacitance rated at 450 V, providing significant bulk energy storage for high-voltage circuits.
• High Ripple-Current Capability: Rated ripple current of 39.2 A at 120 Hz and 54.88 A at 100 kHz to support demanding AC ripple and switching conditions.
• Temperature and Endurance: Operating temperature range −25°C to +105°C with a specified lifetime of 5,000 hours at 105°C under rated conditions.
• Screw-Terminal Radial Can Package: Screw terminal mounting for secure electrical connections; package described as radial, can – screw terminals and sized φ90 × 230L (L: 23 × D: 9 cm).
• Polarized with ±20% Tolerance: Polar capacitor with capacitance tolerance of −20% to +20% (±20%).
• Load-Life and Stability: Endurance specifications require capacitance change within ±20% and leakage current not exceeding initial specified values after rated endurance testing.
• RoHS Compliant: Product is compliant with RoHS requirements.

Typical Applications

• High-voltage power supplies: Bulk smoothing and energy storage where 12,000 µF at 450 V and high ripple-current handling are required.
• Power conversion and DC-link circuits: Supports DC-link filtering for converters and inverters that demand high capacitance and sustained ripple performance.
• Industrial power equipment: Provides bulk capacitance and long-term endurance in high-temperature industrial environments up to 105°C.

Unique Advantages

• Substantial bulk capacitance at high voltage: 12,000 µF at 450 V supplies large energy reserves for high-voltage circuits, reducing the need for parallel parts.
• Measured ripple performance across frequencies: Specified ripple currents of 39.2 A (120 Hz) and 54.88 A (100 kHz) enable reliable operation with both line-frequency and high-frequency switching stress.
• Long operational life at elevated temperature: 5,000-hour lifetime at 105°C supports designs that must sustain continuous high-temperature operation.
• Robust screw-terminal connections: Screw-terminal radial can package provides secure, high-current terminations suitable for heavy-duty power assemblies.
• Conservative tolerance and polarization: ±20% capacitance tolerance and clear polarization simplify specification and assembly in polarized high-voltage circuits.
• RoHS compliance: Meets environmental regulatory requirements for lead-free manufacturing processes.
