LQR2V222MSEFBB

The LQR2V222MSEFBB is a screw-terminal aluminum electrolytic capacitor designed for power conversion and regenerative circuits. It is a polarized, radial-can capacitor with a 2.2 mF (2200 µF) capacitance and a 350 V rated voltage, optimized for high-frequency charge–discharge environments such as AC servomotor drives and general inverters.

This part offers defined ripple-current capability, long-term endurance at elevated temperature, and RoHS compliance, making it suitable for equipment operating in fluctuating-voltage conditions and rectifier/voltage-doubler circuits.

Key Features

• Capacitance and Voltage — 2.2 mF (2200 µF) nominal capacitance at a rated voltage of 350 V, with capacitance tolerance ±20% (120 Hz, 20°C).
• Screw-Terminal Radial Can — Radial, can-style package with screw terminals for secure, low-resistance power connections in high-current assemblies.
• Ripple Current Handling — Rated ripple current: 9.1 A at 120 Hz and 12.74 A at 10 kHz, supporting high-frequency regenerative and switching applications.
• Temperature and Lifetime — Operating range −25°C to +85°C with endurance specified as 5000 hours at 85°C under DC bias plus rated ripple current.
• Electrical Stability — Endurance limits: capacitance change within ±20% and tan δ up to 300% of initial specified value after endurance testing; leakage current remains within initial specified limits.
• Leakage Current Specification — After 5 minutes' application of rated voltage, leakage current is limited to not more than 3√(V) µA or 5 mA, whichever is smaller (at 20°C).
• Low-Temperature Behavior — Impedance ratio Z(−25°C)/Z(+20°C) ≤ 8, supporting operation in cooler environments within the specified range.
• Marking and Sleeve — Printed with white characters on a dark brown sleeve for clear polarity and part identification.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Drives — Handles high-frequency regenerative voltages encountered in motor control feedback and braking circuits.
• General Inverters — Supports DC link and energy-storage roles in inverter topologies where reliable ripple performance is required.
• Rectifier and Voltage-Doubler Circuits — Suited for smoothing and charge storage in rectifier bridges and voltage-doubler arrangements.
• Equipment in Fluctuating-Voltage Environments — Designed for systems exposed to variable supply conditions where robust endurance and leakage characteristics are needed.

Unique Advantages

• Defined High-Frequency Ripple Capability — Published ripple-current ratings at 120 Hz and 10 kHz provide clear guidance for thermal and lifetime budgeting in designs.
• Proven Endurance at Elevated Temperature — 5000-hour endurance at 85°C under rated conditions supports predictable long-term performance in hot operating environments.
• Charge–Discharge Durability — Specified endurance for charge–discharge cycles (20 million cycles per datasheet conditions) for applications with frequent voltage swings.
• Secure Screw-Terminal Mounting — Screw terminals enable robust mechanical and electrical connections for high-current power systems.
• Clear Specification Limits — Leakage current formula, impedance ratio, and tolerance limits are documented to simplify design verification and compliance testing.
• Regulatory Compliance — RoHS compliance for use in regions requiring restricted substance adherence.
