LNU2H222MSEG

The LNU2H222MSEG is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power systems. It delivers 2200 µF capacitance at a 500 V rating and is optimized for inverter circuitry and high-frequency regenerative applications.

Built for demanding environments, this capacitor supports operation from –40 °C to +105 °C with a rated load life of 5000 hours at 105 °C. Its screw-terminal radial can construction and high ripple-current capability make it suitable for robust power-electronics designs such as inverters and servomotor drives.

Key Features

• Electrical — High Voltage & Capacitance: 2200 µF capacitance rated at 500 V DC; the LNU series supports rated voltages up to DC 525 V as a series characteristic.
• Thermal & Reliability: Rated for operation from –40 °C to +105 °C with a load life of 5000 hours at 105 °C under rated ripple current.
• Ripple Current Performance: Handles 8.5 A at 120 Hz and 11.9 A at 10 kHz, supporting both low- and high-frequency ripple environments common in inverter and regenerative circuits.
• Mechanical & Mounting: Screw terminal radial can package for secure, high-current connections; physical dimensions L: 12 × D: 6.35 cm and available terminal/bracket configurations per the LNU series.
• Charge–Discharge Endurance: Designed to cope with high-speed charge–discharge loading, with specified endurance for charge–discharge behavior in the series documentation.
• Environmental Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters: Bulk and smoothing capacitance for inverter power supplies, supporting high-voltage DC links and reducing ripple in industrial inverter systems.
• AC Servomotor Regeneration Circuits: Handles high-frequency regenerative voltages and fast charge–discharge cycles encountered in servomotor drive systems.
• Power Supply Filters: Filtering and energy storage in high-voltage industrial power supplies where extended high-temperature life is required.
• High-Frequency Power Electronics: Suitable where elevated ripple currents at both 120 Hz and 10 kHz are present, such as high-speed switching environments.

Unique Advantages

• High-voltage capability: 500 V rating (series up to 525 V) supports higher DC link voltages used in industrial power electronics.
• Compact high-voltage form factor: Described as smaller sized within the LNU series, providing space savings compared with larger high-voltage cans in the product family.
• Long elevated-temperature life: 5000 hours at 105 °C under rated ripple current offers predictable endurance for continuous high-temperature operation.
• Robust ripple handling: Specified ripple currents of 8.5 A (120 Hz) and 11.9 A (10 kHz) enable use in both mains-frequency and high-frequency switching applications.
• Secure screw-terminal connections: Screw terminal mounting delivers reliable, low-resistance connections for high-current industrial wiring and bus configurations.
• RoHS compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for use in regulated markets.
