LNT2G472MSEG

The LNT2G472MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNT series, offering 4.7 mF (4700 µF) capacitance at a 400 V rating. Designed for general-purpose use, it targets applications that require high capacitance, high ripple current capability and robust thermal endurance.

Key differentiators include screw-terminal mounting for secure electrical and mechanical connections, a wide operating temperature window up to 105°C, and RoHS compliance for environmentally conscious designs.

Key Features

• Capacitance & Tolerance — 4.7 mF (4700 µF) nominal capacitance with a tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Voltage Rating — Rated for 400 V DC, suitable where high-voltage capacitance is required.
• High Ripple Current — Supports 20.7 A at 120 Hz and 28.98 A at 100 kHz, enabling effective smoothing and energy buffering under heavy AC ripple conditions.
• Thermal Endurance — Rated operating temperature range of −25°C to +105°C with a specified load life of 5000 hours at 105°C.
• Package & Mounting — Radial can with screw terminals for secure, low-impedance connections and robust mechanical mounting.
• Polarized Electrolytic — Polar device suitable for DC applications where polarized capacitors are required.
• Dimensions — Size listed as L: 17 cm × D: 6.35 cm with a maximum seated height of 6.693 inches, supporting designs that need a specific footprint and height envelope.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing where a 400 V rating and large capacitance are required.
• DC link and inverter stages — Supports DC link smoothing and ripple handling in industrial power conversion equipment using its high ripple-current capability.
• Uninterruptible power supplies (UPS) and energy buffers — Energy storage and transient suppression in systems that need long-life performance at elevated temperatures.

Unique Advantages

• High ripple-current handling: Ripple ratings of 20.7 A (120 Hz) and 28.98 A (100 kHz) reduce heating and improve performance in high-stress power circuits.
• Extended thermal durability: 5000-hour load life at 105°C provides measurable endurance for sustained high-temperature operation.
• Secure screw-terminal connections: Screw terminals deliver low-impedance, mechanically robust terminations for demanding installations.
• Large capacitance at high voltage: 4700 µF at 400 V enables significant energy storage in designs that require both high voltage and high capacity.
• Regulatory alignment: RoHS compliance supports environmental and supply-chain requirements.
• Clear dimensional specification: Explicit size and seated height data simplify mechanical integration and layout planning.
