LQR2V822MSEH

The LQR2V822MSEH is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LQR series. It provides 8200 µF (8.2 mF) capacitance at a 350 V rated voltage in a radial can with screw terminals, engineered for high‑frequency charge/discharge environments.

This part targets industrial power electronics where high ripple handling and long endurance are required — for example, regenerative circuits in AC servomotors, general inverters, and rectifier circuits such as voltage doublers. It is RoHS compliant and designed for operation across a −25 °C to +85 °C range.

Key Features

• Capacitance & Voltage — 8200 µF (8.2 mF) rated capacitance with a 350 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Package & Mounting — Radial can with screw terminals (screw‑terminal type) suitable for robust bus‑bar or stud connections; physical size L: 15 × D: 7.62 cm.
• High ripple and high‑frequency capability — Rated ripple current of 26.4 A at 120 Hz and 36.96 A at 10 kHz supports demanding regenerative and inverter applications.
• Operating temperature and endurance — Rated for −25 °C to +85 °C with an endurance specification of 5000 hours at 85 °C under DC bias plus rated ripple current.
• Charge–discharge durability — Designed to meet charge–discharge endurance after 20 million cycles (ΔV = rated × 0.3, 3 Hz) at room temperature with defined limits on capacitance change, tan δ, and leakage current.
• Leakage current specification — After 5 minutes at rated voltage, leakage current is ≤ 3√(√V) µA or 5 mA, whichever is smaller (at 20 °C), per datasheet.
• Terminal hardware — Screw terminal construction compatible with M5 nominal bolt diameter for the φ76.2 mm can size used by this part, enabling secure connections for high‑current bus work.
• Regulatory status — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Regenerative motor drives — Energy buffering and smoothing for high‑frequency regenerative voltages in AC servomotors.
• Inverters and power conversion — DC link and bulk energy storage in general inverter systems operating in environments with voltage fluctuation.
• Rectifier / voltage doubler circuits — Bulk smoothing and charge handling in rectifier or voltage‑doubler topologies.
• Industrial equipment — Applications requiring high ripple handling and long endurance at elevated temperatures up to 85 °C.

Unique Advantages

• High energy at high voltage: 8200 µF at 350 V provides substantial bulk capacitance for DC link and smoothing duties in high‑voltage power systems.
• Designed for high ripple: Specified ripple currents at both 120 Hz and 10 kHz enable reliable performance under continuous AC ripple and high‑frequency switching conditions.
• Robust endurance: 5000 hours at 85 °C under rated conditions and validated charge–discharge endurance (20 million cycles) support long service life in demanding applications.
• Secure mechanical connection: Screw‑terminal radial can and M5 terminal compatibility simplify installation and ensure reliable high‑current connections.
• Controlled leakage behavior: Datasheet‑specified leakage limits provide predictable performance after voltage application and during long term use.
• RoHS compliant: Meets RoHS requirements for restricted substances, supporting regulatory needs in many markets.
