LNU2G472MSEHBB

The LNU2G472MSEHBB is a polarized aluminum electrolytic capacitor in a screw‑terminal can package designed for high‑voltage, high‑energy applications. Built on Nichicon’s LNU series architecture, this 4700 µF, 400 V device targets industrial power electronics where robust ripple handling and long endurance at elevated temperatures are required.

Typical use cases include industrial power supplies, inverter circuitry and regenerative/high‑frequency power stages where sustained performance at up to 105°C and high ripple currents are essential.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a 400 V DC rated voltage and ±20% tolerance (120 Hz, 20°C).
• High‑Temperature Endurance — Rated operating temperature range of −40°C to +105°C with a guaranteed load life of 5000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Designed for high ripple environments: 15.8 A at 120 Hz and 22.12 A at 10 kHz, enabling use in both low‑ and high‑frequency power circuits.
• Loss Characteristics — Specified tangent of loss angle (tan δ / dissipation factor) of 0.2 for predictable AC loss behavior in switching and regenerative applications.
• Construction & Mounting — Screw terminal (M5 nominal bolt) radial can for secure electrical and mechanical connection in high‑power assemblies; bracket supplied separately where applicable.
• Physical Size & Packaging — Body diameter φ76.2 mm, length 95 mm (L: 9.5 × D: 7.62 cm), shipped in cardboard packing for mass production handling.
• Environmental Compliance — RoHS‑compliant per provided documentation.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high‑voltage power supplies used for industrial equipment and factory automation.
• Inverter and Motor Drive Circuits — DC link and buffering for inverter circuitry and AC servomotor drives, including high‑speed charge/discharge cycles.
• Regenerative Power Systems — Handling high‑frequency regenerative voltages in braking or energy recovery systems where sustained ripple tolerance and endurance are required.
• High‑Frequency Power Stages — Suitable for high‑frequency switching environments due to elevated ripple current capability at 10 kHz.

Unique Advantages

• Robust High‑Temperature Life: 5000 hours at 105°C under rated ripple current provides predictable service life for demanding industrial applications.
• High Ripple Capability: Specified ripple currents at both 120 Hz and 10 kHz support a wide range of switching frequencies without compromising performance.
• Secure Screw‑Terminal Mounting: M5 screw terminals deliver reliable electrical connection and mechanical stability for high‑current installations.
