LNT2G332MSEG

The LNT2G332MSEG from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series designed for high-voltage, high-ripple applications. It delivers 3.3 mF (3300 µF) capacitance at a 400 V rating with polarized screw-terminal packaging for secure, high-current connections.

Targeted for general-purpose power electronics, this capacitor combines high ripple current capability, extended ambient temperature operation up to 105°C, and a long rated load life to support demanding industrial and power-conversion designs.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 400 V, providing substantial bulk energy storage for high-voltage circuits.
• Screw Terminal Package: Radial can with screw terminals for robust electrical and mechanical connections in panel- or chassis-mounted power systems.
• High Ripple Current: Rated ripple current of 15.4 A at 120 Hz and 21.56 A at 100 kHz to handle significant AC stress in power supplies and converters.
• Temperature & Lifetime: Operates from −25°C to +105°C with a load life of 5,000 hours at 105°C under rated ripple conditions.
• Tolerance & Polarization: Polarized electrolytic construction with capacitance tolerance of ±20% for predictable sizing and design margin.
• Physical Size: Compact high-energy can: length 13 cm × diameter 6.35 cm; designed for screw-terminal mounting. Height seated max specified.
• Regulatory Compliance: RoHS compliant, consistent with environmental directive requirements documented for the series.

Typical Applications

• Power Conversion and DC Bus Filtering: Bulk energy storage and smoothing on high-voltage DC buses, leveraging 3.3 mF at 400 V and high ripple ratings.
• Industrial Power Supplies: Input/output filtering and decoupling in industrial converters where screw-terminal mounting provides secure connections for high current.
• Inverters and UPS Systems: Energy buffering and ripple handling in inverter DC-link stages and uninterruptible power supplies requiring elevated temperature endurance.
• Laboratory and Test Equipment: High-voltage test rigs and bench power modules that require large capacitance, high ripple capability, and robust terminal connections.

Unique Advantages

• High-voltage energy density: 400 V rating combined with 3.3 mF capacitance enables significant single-component energy storage for compact high-voltage designs.
• Robust current handling: Specified ripple currents at both low and high frequencies (15.4 A at 120 Hz, 21.56 A at 100 kHz) reduce the need for parallel parts when addressing AC stress.
• Long endurance at elevated temperature: 5,000-hour load life at 105°C supports extended field operation in thermally demanding installations.
• Secure screw-terminal mounting: Radial can with screw terminals simplifies installation and delivers reliable mechanical and electrical contact for high-current loops.
• Clear specification window: Polarized design with ±20% tolerance and defined operating temperature range (−25°C to +105°C) provides predictable integration into power designs.
• Environmental compliance: RoHS status supports designs with regulatory restrictions on hazardous substances.
