LNC2V472MSEH

The LNC2V472MSEH is a screw‑terminal aluminum electrolytic capacitor from Nichicon designed for industrial power applications. It is a smaller-sized, high ripple‑current capacitor rated at 4700 µF and 350 V with an operating temperature range of −40 °C to +85 °C.

Engineered for inverter circuitry and high-frequency regenerative voltages (such as AC servomotor drives and general inverters), this part delivers long load life under rated ripple current and is RoHS compliant.

Key Features

• Capacitance & Voltage: 4700 µF nominal capacitance with a rated voltage of 350 V and ±20% tolerance at 120 Hz, 20 °C.
• High Ripple Current: Designed for high ripple loading — 15.7 A at 120 Hz and 21.98 A at 100 kHz — to support heavy AC and regenerative duty.
• Long Load Life: Rated for 5000 hours of load life when subjected to rated DC bias plus rated ripple current at 85 °C.
• Robust Charge‑Discharge Endurance: Meets charge‑discharge endurance requirements after 50 million cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature.
• Wide Temperature Range: Operates from −40 °C to +85 °C, suitable for industrial environments within that range.
• Screw Terminal Package: Radial can with screw terminals for secure busbar or bracket mounting; physical size L: 8.0 cm × D: 7.62 cm.
• Electrical Insulation & Withstand: Insulation resistance ≥100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute per datasheet.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies / Inverters: Energy storage and smoothing for inverter front‑ends where sustained ripple handling and long life are required.
• AC Servomotor Regenerative Circuits: Handles high‑frequency regenerative voltages and rapid charge–discharge cycles in servo drives.
• General Inverter Systems: Bulk energy buffering and ripple suppression in general inverter topologies used in industrial equipment.

Unique Advantages

• Smaller footprint with high performance: Specified as smaller-sized while providing higher ripple current versus comparable series (LNX, LNK), enabling space-efficient power module designs.
• High ripple capability across frequencies: Explicit ripple current ratings at both 120 Hz and 100 kHz support designs that encounter broad frequency content.
• Extended loaded life at elevated temperature: 5000 hours rated life at 85 °C under DC bias plus rated ripple current supports long-term reliability in continuous-duty systems.
• Durable under frequent cycling: Proven charge‑discharge endurance (50 million cycles) for applications with frequent energy transfer events.
• Electrical safety margins: High insulation resistance and a 2500 V AC dielectric proof test between terminal and bracket provide verified withstand characteristics.
• Regulatory compliance: RoHS conformity for use in regulated industrial equipment.
