LQR2V332MSEFBN

The LQR2V332MSEFBN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LQR series, featuring 3.3 mF (3300 µF) capacitance at 350 V rated voltage. Its construction and specifications are optimized for high‑speed charge/discharge and high ripple environments.

Designed for industrial power electronics, this radial can with screw terminals is targeted at applications such as AC servomotor regenerative circuits, general inverters, equipment operating in fluctuating voltage environments, and rectifier circuits using a voltage doubler topology.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) nominal capacitance with a 350 V rated voltage and ±20% tolerance for DC link and energy‑storage use.
• High‑speed charge/discharge — Engineered for rapid charge/discharge behavior; specified endurance for 20 million charge/discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• High ripple handling — Rated ripple current of 12.4 A at 120 Hz and 17.36 A at 10 kHz to support high frequency and low frequency ripple in power conversion systems.
• Thermal and endurance rating — Operates over −25°C to +85°C with 5000 hours endurance at 85°C under DC bias plus rated ripple current.
• Robust mounting — Radial can with screw terminals (φ51 format) for secure bolted connections; nominal bolt diameter M5 on the φ51 terminal pitch.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Drives (AC servomotors) — Used for regenerative voltage buffering and smoothing in motor drive regenerative circuits.
• Inverters and Power Converters — DC link and energy storage in general inverters where high ripple and frequent charge/discharge events occur.
• Voltage Doubler Rectifiers — Suitable for rectifier circuits employing voltage doubler topologies that require reliable high‑voltage capacitance.
• Equipment in Fluctuating Voltage Areas — Provides robust smoothing and transient absorption where supply voltage varies significantly.

Unique Advantages
