LQR2V682MSEJBB

The LQR2V682MSEJBB is a screw‑terminal aluminum electrolytic capacitor with a nominal capacitance of 6800 µF and a rated voltage of 350 V. It is designed for high‑speed charge–discharge and heavy‑duty power applications where secure terminal connections and high ripple handling are required.

Targeted use cases include regenerative circuits for AC servomotors, general inverters, voltage‑doubler rectifier circuits and industrial equipment operating in areas with fluctuating voltages. The part is RoHS compliant and specified for operation from −25 °C to +85 °C.

Key Features

• Capacitance and Voltage — 6800 µF nominal capacitance at a rated voltage of 350 V, with capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• Screw Terminal Package — Radial can with screw terminals for robust, low‑impedance connections suitable for heavy current paths and field serviceability.
• High ripple and high‑frequency performance — Rated ripple current of 22.5 A at 120 Hz and 31.5 A at 10 kHz to support power conversion and regenerative loads.
• Wide operating temperature — Specified for −25 °C to +85 °C to cover typical industrial ambient conditions.
• Endurance and charge‑discharge durability — Endurance specified as 5000 hours at 85 °C under D.C. bias plus rated ripple; charge‑discharge behavior tested for 20 million cycles (ΔV = 0.3 × rated voltage, 3 Hz).
• Leakage current specification — After 5 minutes’ application of rated voltage, leakage current is limited to ≤ 3√(V) µA or 5 mA, whichever is smaller (at 20 °C).
• Low‑temperature impedance behavior — Impedance ratio Z(−25 °C)/Z(+20 °C) up to 8, useful for evaluating performance in colder starts or ambient conditions.
• RoHS compliant — Meets the requirements of the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servo and Motor Drives — Energy absorption and regenerative voltage smoothing in AC servomotor drives and motion control systems.
• Inverters and Power Conversion — DC bus and energy buffering for general inverter modules where high ripple current capability is needed.
• Voltage‑Doubler Rectifier Circuits — Filtering and charge storage in rectifier topologies including voltage doublers.
• Industrial Equipment in Fluctuating Voltage Areas — Bulk energy storage and voltage stabilization for equipment exposed to variable supply conditions.

Unique Advantages

• High ripple current handling: Rated 22.5 A (120 Hz) and 31.5 A (10 kHz), enabling reliable operation under heavy AC ripple and high‑frequency regenerative events.
• Robust mechanical connection: Screw‑terminal, radial can package provides secure, serviceable terminations for high‑current power assemblies.
• Proven endurance: 5000 hours at 85 °C under rated conditions and charge‑discharge durability to 20 million cycles give long operational life in demanding power systems.
• Clear leakage limits: Defined leakage current criteria (≤ 3√(V) µA or 5 mA after 5 minutes) support predictable power‑up behavior and system design.
• Designed for temperature variation: Operation from −25 °C to +85 °C with documented impedance ratio for low‑temperature performance aids system thermal planning.
• Regulatory compliance: RoHS compliance simplifies environmental and procurement compliance in industrial builds.
