Overview of LNX2W123MSEJ – Aluminum Electrolytic Screw Terminal Capacitor, 12,000 µF, 450 V

The LNX2W123MSEJ is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage, high‑ripple industrial power applications. It provides 12,000 µF capacitance at a 450 V rating in a large can‑style package (φ90×220L / L: 22 × D: 9 cm) with screw terminals for secure power connections.

This part targets industrial power supplies and inverter circuitry and other general‑purpose power systems where sustained ripple handling, long operational life, and reliable DC energy storage are required.

Key Features

  • Capacitance & Rated Voltage — 12,000 µF nominal capacitance at 450 V rated voltage, suitable for large energy storage and smoothing in high‑voltage power rails.
  • High Ripple Current — Rated ripple current of 26.9 A at 120 Hz (low frequency) and 37.66 A at 100 kHz (high frequency) to support demanding ripple conditions in power converters.
  • Long Endurance — Specified lifetime of 20,000 hours at +85°C when subjected to rated ripple current, enabling extended continuous operation in demanding environments.
  • Operating Temperature Range — -25°C to +85°C operating range to accommodate a wide span of industrial ambient conditions.
  • Screw Terminal Mounting — Radial can package with screw terminals for robust, low‑impedance power connections in cabinet and chassis installations.
  • Leakage Current & Tolerance — Maximum leakage current specified at 5,000 µA and capacitance tolerance of ±20% at 120 Hz, 20°C, providing predictable performance for power design margining.
  • Physical & Packaging — Large form factor (φ90×220L; L: 22 × D: 9 cm) supplied in cardboard packing; mass production status supports volume deployment.
  • Regulatory — RoHS compliant for material restrictions in regulated product lines.

Typical Applications

  • Industrial Power Supplies — Bulk energy storage and smoothing for high‑voltage supply rails in industrial converters and power distribution systems.
  • Inverter and Motor Drive Systems — DC link and ripple absorption in inverter circuits where high ripple current capability and long life are required.
  • General Purpose Power Systems — Energy buffering and decoupling in large choke and filter networks for commercial and industrial equipment.

Unique Advantages

  • Designed for sustained ripple — High specified ripple current at both 120 Hz and 100 kHz supports a wide range of converter switching environments.
  • Extended operational life — 20,000 hours endurance at 85°C under standard ripple conditions reduces maintenance and replacement frequency in continuous‑duty installations.
  • Secure, low‑resistance connections — Screw terminal mounting simplifies installation and delivers reliable current transfer for high‑power assemblies.
  • Large energy capacity — 12,000 µF at 450 V provides significant stored energy per unit for smoothing and transient support in high‑voltage systems.
  • Production‑ready supply — Cardboard packing and mass production status facilitate procurement and deployment at scale.
  • Regulatory compliance — RoHS compliance supports use in products that must meet restricted‑substance requirements.
