LNU2H472MSEJBN

The LNU2H472MSEJBN is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage industrial power applications. It delivers 4700 µF capacitance at a 500 V rated voltage and is offered in a compact, high‑voltage screw‑terminal can optimized for inverter and regenerative circuits.

Engineered for demanding environments, this part supports a wide operating range (−40 °C to +105 °C), a rated voltage range up to DC 525 V, and a load life of 5000 hours at 105 °C under applied ripple current, making it suitable for inverter power supplies and high‑frequency regenerative voltage circuits.

Key Features

• Capacitance & tolerance — 4700 µF nominal with ±20% tolerance (measured at 120 Hz, 20 °C), providing bulk energy storage for power electronics.
• High rated voltage — 500 V nominal rating; series rated voltage range up to DC 525 V for high‑voltage systems.
• Elevated temperature endurance — Designed for operation from −40 °C to +105 °C with a rated load life of 5000 hours at 105 °C when subjected to rated ripple current.
• High ripple current capability — 13.9 A at 120 Hz and 19.46 A at 10 kHz, suitable for high‑frequency inverter and regenerative loads.
• Screw terminal mounting — Radial can with screw terminals for secure electrical and mechanical connections in industrial assemblies; nominal bolt size (series drawing) uses M5.
• Compact high‑voltage form factor — Smaller sized than the LNT series; package dimensions listed as L: 12.5 × D: 9 cm and a maximum seated height of 4.921 in, enabling higher voltage capability in a reduced footprint.
• Charge–discharge durability — Endurance for high‑speed charge/discharge behavior, meeting series specifications after 50 million cycles (ΔV = rated voltage ±0.3, 3 Hz cycle).
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk DC link and energy buffering for inverter circuitry in industrial drives.
• AC servomotor regenerative circuits — Handles high‑frequency regenerative voltage and fast charge/discharge events in servo applications.
• General inverters — Energy storage and ripple smoothing in high‑voltage inverter systems.

Unique Advantages

• High‑voltage capability: 500 V nominal rating and series support up to DC 525 V allow direct use in high‑voltage DC link applications.
