LNUN7222MSEGBN

The LNUN7222MSEGBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNU series designed for high‑voltage industrial power applications. It is a polarized, radial can type capacitor rated at 2200 µF and DC 525 V, optimized for inverter circuitry and high‑frequency regenerative voltage environments such as AC servomotor and general inverter systems.

Engineered for demanding thermal and electrical conditions, the device is specified for operation from −40 °C to +105 °C, a rated ripple current capability at both low and high frequencies, and a 5000‑hour load life at 105 °C under applied ripple current.

Key Features

• High Voltage Rating — Rated voltage up to DC 525 V, suitable for high‑voltage inverter and regenerative circuits.
• Capacitance and Tolerance — 2.2 mF (2200 µF) nominal capacitance with ±20% tolerance (120 Hz, 20 °C).
• Thermal Endurance — Operates across −40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under rated ripple current.
• High Ripple Current Capability — Supports 9.2 A at 120 Hz and 12.88 A at 10 kHz, enabling robust handling of AC ripple and high‑frequency loading.
• Screw Terminal, Radial Can Package — Screw terminal mounting and radial can construction provide secure connections for industrial assemblies.
• Designed for Fast Charge–Discharge — Engineered to cope with high speed charge–discharge cycles and high‑frequency regenerative voltage conditions.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Energy storage and smoothing in inverter DC link circuits for industrial drives and power supplies.
• AC Servomotor Regenerative Circuits — Handling high‑frequency regenerative voltages in motor control and servo drive systems.
• General Inverter and Motor Drive Systems — Bulk and decoupling capacitance where high voltage, high ripple capability, and thermal endurance are required.

Unique Advantages

• High‑Voltage Capability: DC 525 V rating enables use in higher voltage DC link and regenerative circuits without up‑rating multiple lower‑voltage parts.
• Compact Form Factor: LNU series is described as "High Voltage, Smaller Sized" than the LNT series, helping save board or chassis space in dense power assemblies.
• Long Thermal Life: 5000 hours at 105 °C under rated ripple current delivers predictable lifetime performance in elevated temperature enclosures.
• Wide Temperature Range: −40 °C to +105 °C operation supports use across a broad range of industrial environments.
• Strong Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz support both low‑frequency smoothing and high‑frequency regenerative loads.
• Secure Mechanical Termination: Screw terminal and radial can package provide robust electrical and mechanical connections for industrial assemblies.
