LQR2G103MSEJBN

The LQR2G103MSEJBN from Nichicon is a screw‑terminal aluminum electrolytic capacitor designed for high‑speed charge/discharge environments. As part of the LQR series, it is optimized for high‑frequency regenerative voltages and fluctuating supply conditions commonly found in inverter and motor drive systems.

Key attributes include a 400 V rated voltage, 10 mF capacitance, low equivalent series resistance and high ripple current capability—features that support energy buffering and transient handling in power conversion applications.

Key Features

• Electrical Performance 10 mF capacitance with ±20% tolerance and polarization appropriate for DC power bus applications.
• High Ripple Current Capability Rated ripple current of 32.7 A at 120 Hz and 45.78 A at 10 kHz to handle both low‑ and high‑frequency ripple in inverter and regenerative circuits.
• Low ESR Equivalent series resistance of 3.4 mΩ measured at 120 Hz for reduced power loss and improved voltage stability under load.
• Robust Endurance Specified lifetime of 5000 hours at 85 °C under rated conditions, with endurance against charge/discharge cycling per series specifications.
• Package & Mounting Radial can with screw terminals for secure, high‑current connections suitable for panel or chassis mounting.
• Operating Range & Compliance Rated for operation from −25 °C to +85 °C and compliant with the RoHS Directive (2011/65/EU, (EU)2015/863).
• Compact Footprint Physical size noted as L: 15 × D: 9 cm for layout and mechanical planning.

Typical Applications

• AC Servomotor Drives and Regenerative Systems — Handles high‑frequency regenerative voltages produced during braking and energy recovery.
• General Inverters — Provides DC bus stabilization and transient energy buffering in inverter power stages.
• Voltage Doubler Rectifier Circuits — Suited for rectifier configurations that require stable capacitance under fluctuating voltages.
• Equipment in Voltage‑Fluctuating Areas — Designed for systems exposed to variable supply conditions where robust charge/discharge performance is required.

Unique Advantages

• High ripple handling: Specified ripple currents at 120 Hz and 10 kHz enable reliable operation across a wide range of switching and line frequencies.
• Low loss under load: Low ESR (3.4 mΩ at 120 Hz) reduces internal heating and improves efficiency in high‑current circuits.
• Screw‑terminal reliability: Screw terminals provide secure, low‑resistance connections for high‑current and vibration‑prone installations.
• Endurance at elevated temperature: 5000‑hour rating at 85 °C supports long service life in demanding thermal environments.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for end products.
