Overview of LNT2W123MSEJ – 450 V Screw-Terminal Aluminum Electrolytic Capacitor, 12 mF

The LNT2W123MSEJ is a Nichicon LNT series aluminum electrolytic capacitor in a screw-terminal can package, rated at 450 V with 12 mF (12,000 µF) capacitance and ±20% tolerance. It is a polarized, radial screw-terminal component designed for general-purpose power applications that require high capacitance, high-voltage capability and robust ripple handling.

Key value propositions include a 105°C rated operating range with a 5,000-hour endurance at 105°C, substantial low- and high-frequency ripple current capacity, and RoHS compliance—making it suitable for demanding industrial and power-electronics installations where durable bulk energy storage and smoothing are needed.

Key Features

  • High Capacitance & Voltage: 12,000 µF (12 mF) nominal capacitance at a 450 V rated voltage, specified with ±20% tolerance at 120 Hz, 20°C.
  • Screw-Terminal Can Package: Radial, screw-terminal construction (φ90 × 230L) for secure bolted connections and ease of installation in high-current circuits.
  • High Ripple Current Capability: 39.2 A low-frequency ripple current (120 Hz) and 54.88 A high-frequency ripple current (100 kHz), supporting substantial AC current loading in smoothing and filtering roles.
  • Endurance at Elevated Temperature: Rated for 5,000 hours of load life at 105°C with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
  • Leakage and Loss Characteristics: Specified leakage current of 5,000 µA and maximum tan δ of 0.2 (measurement conditions per product specification).
  • Operating Temperature Range: –25°C to +105°C, matching the product’s high-voltage category and intended application environments.
  • Regulatory Compliance: RoHS compliant as stated in the product information and datasheet.

Typical Applications

  • Industrial Power Electronics: Bulk energy storage and DC link smoothing where a 450 V rated, high-capacitance screw-terminal capacitor is required.
  • Power Conversion Systems: Filtering and ripple handling in converters and inverters that demand high ripple-current endurance at both low and high frequencies.
  • Large-Scale DC Bus Filters: Use in DC bus or intermediate circuits where high capacitance, robust leakage specifications, and secured screw-terminals facilitate installation and maintenance.

Unique Advantages

  • High Voltage with Large Capacitance: 450 V rating combined with 12,000 µF provides significant stored energy density for high-voltage designs.
  • Screw-Terminal Robustness: Bolted screw terminals simplify high-current connections and mechanical mounting for industrial systems.
  • Designed for Elevated-Temperature Duty: 5,000-hour endurance at 105°C delivers predictable performance and lifecycle expectations under rated ripple and bias conditions.
  • Strong Ripple-Handling Performance: Specified ripple currents at 120 Hz and 100 kHz support both mains-frequency and switching-frequency smoothing needs.
  • Clear Electrical Limits: Defined leakage current (5,000 µA) and tan δ (0.2) enable straightforward power-budgeting and thermal design.
  • RoHS Compliance: Conforms to RoHS requirements for regulations-driven designs.

Why Choose LNT2W123MSEJ?

The LNT2W123MSEJ is positioned for designs that require a high-voltage aluminum electrolytic capacitor with substantial capacitance, reliable ripple performance, and durable screw-terminal connections. Its combination of 450 V rating, 12,000 µF capacitance, and specified ripple current figures make it appropriate for heavy-duty power-electronics and industrial filter applications where long-term endurance at elevated temperature is a priority.

For engineers and procurement teams building robust power subsystems, this part offers predictable electrical limits (leakage, tan δ) and a clear mechanical footprint (φ90 × 230L, radial can with screw terminals), simplifying integration and lifecycle planning while adhering to RoHS requirements.
