Overview of LNX2H123MSEK – 12,000 µF, 500 V Screw Terminal Aluminum Electrolytic Capacitor

The LNX2H123MSEK is an aluminum electrolytic capacitor in a screw‑terminal, radial can package designed for high‑voltage, high‑ripple applications. With a 12,000 µF nominal capacitance at 500 V and a polarized design, it targets industrial power electronics where robust DC filtering and energy storage are required.

Engineered for inverter circuitry and industrial power supplies, this capacitor delivers high ripple handling and extended field life at elevated temperatures while offering a flame‑retardant electrolyte option and RoHS compliance.

Key Features

  • High Capacitance, Extra‑High Voltage — 12,000 µF nominal capacitance rated at 500 V for DC bus and energy‑storage applications requiring elevated voltage headroom.
  • Screw Terminal Mounting — Radial can with screw terminals for secure mechanical and electrical connection in heavy‑current power systems.
  • High Ripple Current Capability — Rated ripple current of 27.8 A at 120 Hz and 38.92 A at 100 kHz to support demanding inverter and power‑supply ripple environments.
  • Endurance at Elevated Temperature — Designed for long life under ripple load with a specified endurance of 5,000 hours at +85°C for parts rated at 500 V.
  • Operating Temperature Range — Specified for operation from −25 °C to +85 °C to accommodate a wide range of industrial conditions.
  • Capacitance Tolerance — ±20% (measured at 120 Hz, 20 °C), enabling predictable filtering and energy storage behavior.
  • Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller, ensuring controlled self‑discharge characteristics.
  • Safety & Compliance — Flame‑retardant electrolyte option available; component is RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

  • Industrial Power Supplies — Bulk DC filtering and energy stabilization on high‑voltage rails for switch‑mode and line‑side power stages.
  • Inverter Drives — DC bus smoothing and ripple absorption for motor drive and frequency‑conversion systems handling high ripple currents.
  • Power Electronics Modules — Energy storage and transient buffering in medium‑ to high‑voltage converter assemblies.

Unique Advantages

  • High Voltage Capability: 500 V rating supports elevated DC bus voltages without series stacking, simplifying board layout.
  • Designed for High Ripple: Substantial ripple‑current ratings at both low and high frequencies reduce heating and extend system life under dynamic loads.
  • Robust Mechanical Connection: Screw terminals provide secure, low‑impedance connections suitable for heavy‑current installations.
  • Long Endurance at Elevated Temperature: Specified 5,000 hours at +85 °C under rated conditions for reliable long‑term operation in industrial environments.
  • Controlled Leakage Behavior: Defined leakage limits ensure predictable charge retention and safe discharge characteristics after power removal.
  • Regulatory Compliance and Safety Option: RoHS compliance and an available flame‑retardant electrolyte support regulatory and safety considerations in equipment design.
