LQR2V103MSEHBB

The LQR2V103MSEHBB is an aluminum electrolytic capacitor from Nichicon's LQR series, offered in a screw-terminal radial can package. It is engineered for high‑speed charge–discharge duty and designed for use in high‑frequency regenerative voltage environments such as AC servomotors and general inverters.

With a 350 V rated voltage, 10 mF capacitance and operation across −25 °C to +85 °C, this screw‑terminal capacitor provides high ripple handling and long endurance for equipment exposed to fluctuating voltages and rectifier circuits such as voltage doublers.

Key Features

• Capacitance & Rated Voltage — 10 mF nominal capacitance with a 350 V rated voltage and tolerance of −20% to +20%.
• High‑speed Charge–Discharge Design — Part of the LQR series built for high speed charge–discharge operation, suited to regenerative and inverter applications.
• Ripple Current Performance — Rated ripple current of 31.1 A at 120 Hz and 43.54 A at 10 kHz, supporting high‑frequency energy cycling.
• Thermal & Lifetime Ratings — Operating temperature range −25 °C to +85 °C and specified lifetime of 5000 hours at 85 °C under rated conditions.
• Endurance & Charge‑Discharge Reliability — Meets endurance criteria after 20 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) and after DC bias plus rated ripple current for 5000 hours at 85 °C.
• Mounting & Package — Screw terminal radial can with dimensions L: 17 cm × D: 7.62 cm and a seated height up to 6.693 inch for robust mechanical connections.
• RoHS Compliance — Compliant with RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Regenerative Systems — Handles high‑frequency regenerative voltage for energy capture and smoothing in servo drives.
• General Inverters — Used for DC link and buffering duties where frequent charge–discharge events occur and ripple current capability is required.
• Voltage Doubler Rectifier Circuits — Suited to rectifier circuits with fluctuating voltages, including voltage doubler topologies.
• Equipment in Voltage‑Fluctuating Areas — Provides stable capacitance and endurance for systems exposed to variable supply conditions.
