LNU2G332MSEGBB

The LNU2G332MSEGBB from Nichicon is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power electronics. It combines a 3.3 mF capacitance with a 400 V rating and a compact radial can package optimized for inverter and regenerative circuits.

Built for demanding environments, this capacitor supports wide temperature operation and sustained ripple loading, making it well suited for industrial power supplies, inverter circuitry and high-frequency regenerative voltage applications such as AC servomotors.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for power conversion circuits.
• High Temperature Operation — Specified for operation from −40°C to +105°C to support elevated ambient and enclosure temperatures common in industrial systems.
• Long Load Life — Rated load life of 5000 hours at 105°C under applied ripple current, supporting extended duty in inverter and power-supply applications.
• High Ripple Current Capability — Handles 13.6 A at 120 Hz and 19.04 A at 10 kHz, enabling effective smoothing and energy transfer under both low- and high-frequency ripple conditions.
• Screw Terminal, Radial Can Package — Robust screw-terminal mounting for secure, low-impedance connections; bracket supplied separately for installation flexibility.
• Leakage, Insulation & Voltage Proof — Leakage current specified per 3√CV (μA) or 5 mA limit; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket.
• Charge–Discharge Endurance — Designed to withstand repetitive charge–discharge stress (datasheet test: 50 million cycles at specified conditions) while meeting post-test capacitance, tan δ and leakage criteria.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk energy storage and smoothing in inverter DC-link circuits for motor drives and power converters.
• AC Servomotor Regeneration — Supports high-frequency regenerative voltage and repeated charge–discharge loading in servo and motion systems.
• General Power Supplies — High-voltage filtering and energy buffering in industrial power supplies and converters.
• High-Speed Charge–Discharge Circuits — Suited for designs requiring rapid energy transfer and frequent cycling under high voltage stress.

Unique Advantages

• Compact high-voltage design: 400 V rating in a smaller footprint compared with earlier LNT-series parts, enabling space-efficient high-voltage energy storage.
• High ripple tolerance: Specified ripple current ratings at both 120 Hz and 10 kHz allow reliable operation across a range of switching and regenerative frequencies.
• Durable under elevated temperature: 5000-hour rated life at 105°C provides predictable longevity in hot industrial environments.
• Secure screw-terminal connections: Radial can with screw terminals offers low-impedance, reliable mounting for high-current DC-link applications.
• Validated electrical safety margins: Insulation resistance and voltage-proof test limits between terminal and bracket reduce risk in high-voltage assemblies.
• RoHS compliant: Meets current RoHS requirements for environmental and regulatory consistency.
