LNUN7222MSEGBB

The LNUN7222MSEGBB is a Nichicon LNU-series screw terminal aluminum electrolytic capacitor designed for high-voltage power applications. It pairs a 2.2 mF (2200 µF) capacitance with a 525 V DC rating in a compact radial can with screw terminals for secure, high-current connections.

Engineered for industrial power circuitry, this capacitor supports inverter and regenerative circuits where elevated voltage, high ripple handling and long endurance at 105°C are required.

Key Features

• High Voltage Rating — Rated to 525 V DC to support high-voltage inverter and regenerative applications.
• Large Capacitance — 2.2 mF (2200 µF) nominal capacitance with ±20% tolerance for energy storage and smoothing.
• Robust Ripple Performance — Low-frequency ripple current 9.2 A (120 Hz) and high-frequency ripple current 12.88 A (10 kHz) to handle heavy AC loading.
• Endurance at Elevated Temperature — 5000 hours rated life at 105°C under applied ripple current, enabling sustained operation in demanding thermal environments.
• Wide Operating Temperature Range — −40°C to +105°C operation for broad industrial use.
• Low Loss Tangent — Specified tan δ of 0.2 for predictable dissipation behavior.
• Screw Terminal Mounting — Radial can with screw terminals for secure mechanical and electrical connection in high-current assemblies.
• Leakage Current — Leakage current specified at 3220 µA, measurable after rated voltage application.
• Compact Size — φ63.5 × 135 mm package (L: 13.5 cm × D: 6.35 cm) that balances energy density with installation footprint.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Industrial Inverters — Energy storage and smoothing in inverter power stages for motor drives and industrial equipment.
• Regenerative Drive Circuits — Supports high-frequency regenerative voltages common in AC servomotor and drive systems.
• High-Voltage Power Supplies — Bulk capacitance and high ripple tolerance for industrial DC bus and power supply filtering.

Unique Advantages

• High-Voltage Capability: 525 V rating enables use directly on high-voltage DC buses without series stacking.
• High Ripple Handling: Specified low- and high-frequency ripple currents (9.2 A @120 Hz, 12.88 A @10 kHz) reduce thermal stress under heavy AC loading.
• Long Endurance at 105°C: 5000-hour rated life under ripple load provides predictable service life for industrial applications.
• Secure Mechanical Connection: Screw terminal mounting simplifies installation and ensures robust contact in high-current assemblies.
• Broad Temperature Range: −40°C to +105°C operation accommodates a wide range of industrial environments.
• Series Proven Design: Part of the Nichicon LNU family, designed for high-voltage, smaller-sized applications in inverter and regenerative circuits.
