LNU2H222MTEG

The LNU2H222MTEG is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power applications. It provides 2200 µF capacitance at a 500 V DC rating in a radial can with screw terminals and stud-bolt mounting.

Engineered for inverter and regenerative-power environments, this part combines high ripple-current capability, a wide operating temperature range, and a 5000-hour load life at 105°C for robust performance in demanding systems.

Key Features

• Electrical Capacity: 2.2 mF (2200 µF) with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and smoothing in high-voltage circuits.
• High Voltage Rating: Rated for 500 V DC; part of a series rated up to DC525 V, enabling use in higher-voltage inverter and power-supply designs.
• High Ripple Current Handling: Rated ripple current of 8.5 A at 120 Hz and 11.9 A at 10 kHz, supporting high-frequency and regenerative loads common in motor drives and inverters.
• Thermal and Lifetime Performance: Operating temperature range from −40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple conditions.
• Leakage and Loss Characteristics: Specified leakage current of 3140 µA and a tangent of loss angle (tan δ) of 0.2, enabling predictable loss and self-discharge behavior at 120 Hz.
• Mechanical & Mounting: Radial can with screw terminals and stud-bolt mount (nominal bolt M5 for φ63.5 case), physical size approximately φ63.5 × 120 mm (L: 12 cm × D: 6.35 cm) for secure, serviceable connections.
• Regulatory: RoHS compliant.

Typical Applications

• Industrial Inverters: Bulk DC-link and smoothing capacitor for inverter power supplies, benefiting from high voltage rating and ripple-current capability.
• AC Servo and Motor Drives: Support for regenerative braking and high-frequency charge–discharge cycles where sustained ripple handling and long life are required.
• High-Voltage Power Supplies: Energy storage and filtering in high-voltage DC power systems that operate across a wide temperature range.
• Regenerative Power Circuits: Suited to circuits with frequent charge/discharge cycles—designed to meet endurance requirements for repeated high-speed cycling.

Unique Advantages

• High-voltage capability: 500 V rating (series up to DC525 V) lets designers reduce series stacking or accommodate higher DC-link voltages.
• Secure screw-terminal mounting: Stud-bolt (M5) and screw terminals provide robust, serviceable electrical connections for high-current installations.
• Designed for high ripple and high-frequency loads: Ripple current ratings at 120 Hz and 10 kHz support both mains-frequency and high-frequency inverter environments.
• Long-term thermal endurance: 5000 hours at 105°C under rated ripple current provides predictable lifetime performance in hot operating conditions.
• Compact high-voltage footprint: Series design targets higher voltage in a smaller package footprint relative to comparable designs, aiding dense power assemblies.
• RoHS compliance: Meets environmental regulatory requirements for lead-free applications.
