LQR2V123MSEHBN

The LQR2V123MSEHBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LQR series, rated at 12,000 µF and 350 V. It is designed for high-frequency regenerative voltage applications and power-electronics environments that experience voltage fluctuation.

With a radial can screw-terminal package, RoHS compliance, and datasheet-backed endurance characteristics, this capacitor addresses needs for high ripple handling, robust connections, and long-term operation up to 85°C.

Key Features

• Capacitance & Voltage  12,000 µF nominal capacitance with a rated voltage of 350 V and a tolerance of ±20% (measured at 120 Hz, 20°C).
• High Ripple Current Handling  Ripple current capability of 35.7 A at 120 Hz and 49.98 A at 10 kHz, supporting high-frequency regenerative and inverter applications.
• Screw-Terminal Package  Radial can with screw terminals for secure, low-resistance power connections in heavy-current assemblies.
• Operating Temperature & Lifetime  Rated for −25°C to +85°C with an endurance rating of 5000 hours at 85°C under DC bias plus rated ripple current.
• Endurance & Charge–Discharge Durability  Meets endurance requirements after 5000 hours at 85°C (capacitance change within ±20%, tan δ ≤ 300% of initial, leakage ≤ initial). Also specified for 20 million charge–discharge cycles at room temperature (ΔV = rated × 0.3, 3 Hz).
• Low-Temperature Stability  Impedance ratio Z(−25°C)/Z(+20°C) ≤ 8, supporting performance in colder conditions within the rated temperature range.
• 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).
• RoHS Compliance & Marking  Compliant with RoHS (2011/65/EU, (EU)2015/863); sleeve marked with white letters on a dark brown background.

Typical Applications

• AC Servomotor Regeneration  Used for high-frequency regenerative voltage handling in AC servomotor drive systems.
• General Inverters  Suited for DC-link and filtering duties in inverter topologies where high ripple currents occur.
• Equipment in Fluctuating Voltage Areas  Applied in systems exposed to variable supply conditions where stable energy buffering and endurance are required.
• Rectifier / Voltage Doubler Circuits  Suitable for use in rectifier circuits including voltage doubler configurations requiring large capacitance and high-voltage rating.

Unique Advantages

• Focused for High-Frequency Power Electronics: Ripple current ratings at both 120 Hz and 10 kHz plus explicit suitability for regenerative voltage make it appropriate for high-speed charge/discharge environments.
• Reliable Screw-Terminal Connections: Screw terminals provide mechanically secure and low-impedance connections for high-current systems, simplifying installation and serviceability.
• Datasheet-Backed Endurance: Specified endurance of 5000 hours at 85°C with defined limits on capacitance, loss tangent, and leakage current gives predictable life in elevated-temperature use.
• High Charge–Discharge Durability: Tested for 20 million charge–discharge cycles (ΔV = 0.3 × rated) with maintained electrical characteristics, supporting repetitive energy-transfer applications.
• Wide Operating Range: Rated from −25°C to +85°C to accommodate a broad range of industrial environments.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products requiring restricted-substance conformance.
