LNX2G123MSEJBN

The LNX2G123MSEJBN is an aluminum electrolytic capacitor in a screw‑terminal radial can package, rated at 12,000 µF and 400 V. It is designed for extra‑high voltage applications that demand high ripple current handling and long operational life.

Suited for industrial power supplies and inverter circuitry, this part delivers sustained performance with a 20,000‑hour life at +85°C under rated ripple current, and is RoHS compliant.

Key Features

• Capacitance & Voltage: 12,000 µF nominal capacitance at a 400 V rated voltage, with tolerance ±20% (at 120 Hz, 20°C).
• High Ripple Current: Designed for heavy ripple environments—25.5 A at 120 Hz and 35.7 A at 100 kHz as specified for this part.
• Long Endurance: Rated for 20,000 hours of standard ripple‑current operation at +85°C when restored to 20°C (endurance conditions per series specification).
• Robust Package & Mounting: Radial can with screw terminals for secure connections; φ90 size with screw terminals and M5 nominal bolt diameter for this diameter class.
• Operating Temperature Range: −25°C to +85°C, suitable for industrial ambient conditions defined in the series specification.
• Leakage Current Limit: Leakage after 5 minutes at rated voltage is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C), per the datasheet formula.
• Low‑Temperature Stability: Impedance stability specified with Z(−25°C)/Z(+20°C) ≤ 8 for rated voltages in the series.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Suited for use in industrial power supplies where inverter circuitry requires high voltage, high ripple‑current capacitors.
• Inverter Systems: Designed for inverter circuitry and similar power conversion equipment that demand extra‑high voltage and robust ripple handling.
• General Purpose High‑Voltage Equipment: Applicable where a high‑capacitance, polar aluminum electrolytic with screw terminals is required for long‑life operation.

Unique Advantages

• High Ripple Handling: Specified ripple currents of 25.5 A (120 Hz) and 35.7 A (100 kHz) provide capacity for demanding power‑conversion loads.
• Extra‑High Voltage Capability: 400 V rated voltage supports high‑voltage DC applications within the series' 350–550 V range.
• Extended Service Life: 20,000 hours at +85°C under rated ripple conditions reduces replacement frequency and maintenance in continuous‑operation installations.
• Secure Screw‑Terminal Mounting: Radial can with screw terminals (φ90 class uses M5 bolt nominal diameter) for reliable mechanical and electrical connections in industrial assemblies.
• Measured Leakage Specification: Leakage current governed by the datasheet formula (≤ 3√(C·V) µA or 5 mA after 5 minutes at 20°C) for predictable performance during system commissioning.
• RoHS Compliant: Conforms to EU RoHS directives (2011/65/EU, (EU)2015/863) for environmental compliance.
