LNT2G472MSEGBB

The LNT2G472MSEGBB from Nichicon is a screw-terminal, aluminum electrolytic capacitor in the LNT series designed for high-voltage, high-capacitance applications. With a nominal capacitance of 4700 µF at 400 V and a 105°C rating, it targets general-purpose power electronics designs that require substantial bulk energy storage and high ripple-current capability.

This radial, can-style capacitor with screw terminals combines high ripple-current performance and extended high-temperature endurance for reliable operation in demanding industrial and power-conversion environments.

Key Features

• High Capacitance and Voltage — 4700 µF (4.7 mF) nominal capacitance rated at 400 V for high-energy bulk storage and DC link applications.
• High Ripple-Current Handling — Rated ripple current of 20.7 A at 120 Hz and 28.98 A at 100 kHz to support designs with significant AC ripple and switching stress.
• Screw Terminal Package — Radial can package with screw terminals for secure, low-resistance high-current connections and robust mechanical mounting.
• High-Temperature Endurance — Operating temperature range of –25°C to +105°C with a rated lifetime of 5000 hours at 105°C for sustained performance under elevated thermal conditions.
• Capacitance Tolerance and Polarization — ±20% tolerance at 120 Hz, polarized construction for applications that require correct polarity handling.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.
• Physical Dimensions — Compact form factor specified as L: 17 × D: 6.35 cm in a radial can with screw terminals (see product documentation for detailed dimensions and terminal specifications).

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage where 400 V rating and high capacitance reduce output ripple and stabilize DC rails.
• DC link and inverter filters — Suitable for DC-link filtering in power converters and inverters, leveraging high ripple-current capability to handle switching currents.
• Industrial power systems — Used in industrial converters and power-conditioning equipment that require durable, high-temperature-capable capacitors.
• UPS and backup power modules — Bulk storage and buffering in uninterruptible power supplies and energy buffering modules requiring reliable high-voltage capacitance.

Unique Advantages

• High energy density at 400 V: Large 4700 µF capacitance paired with a 400 V rating provides substantial bulk energy storage in a screw-terminal package.
• Engineered for ripple-intensive use: Specified ripple currents at both low and high frequencies (20.7 A @120 Hz, 28.98 A @100 kHz) support designs with significant AC stress from switching devices.
• Designed for elevated temperatures: Rated to operate up to 105°C with a 5000-hour endurance rating at that temperature for improved long-term reliability in hot environments.
• Robust electrical and mechanical connections: Screw terminal mounting provides secure, low-impedance connections for high-current applications and simplifies installation and maintenance.
• Compliance and predictable tolerance: ±20% capacitance tolerance and RoHS compliance make it straightforward to specify for regulated and repeatable production designs.
