LQR2G152MSEFBN

The LQR2G152MSEFBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for power-electronics applications. It delivers 1500 µF at 400 V with an 85°C category temperature and is optimized for high-speed charge–discharge and high-frequency regenerative environments.

Typical use cases include AC servomotor regenerative circuits, general inverters, equipment operating in fluctuating-voltage areas, and rectifier circuits for voltage-doubler topologies. Its construction and specified endurance make it suitable for industrial power systems requiring reliable bulk energy storage and ripple handling.

Key Features

• Capacitance and Voltage — Rated capacitance 1.5 mF (1500 µF) at a rated voltage of 400 V with a tolerance of ±20% (120 Hz, 20°C).
• Screw Terminal Package — Radial can with screw terminals for secure bolted connections in high-current power assemblies.
• High-frequency and Ripple Performance — Ripple current ratings of 7.5 A at 120 Hz and 10.5 A at 10 kHz support application-relevant AC and switching ripple conditions.
• Temperature Range — Category temperature range from −25°C to +85°C for industrial ambient conditions.
• Endurance and Charge–Discharge Reliability — Specified endurance of 5000 hours at 85°C under D.C. bias plus rated ripple current; designed to meet charge–discharge endurance tests (20 million cycles at ΔV = rated × 0.3, 3 Hz) with limits on capacitance change, tan δ and leakage current.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√(V) µA or 5 mA, whichever is smaller (at 20°C).
• Low-temperature Impedance — Impedance ratio Z(−25°C)/Z(+20°C) ≤ 8 for predictable behavior in cooler operating conditions.
• Physical Size & Mounting — Dimensions L: 8.0 cm × D: 5.1 cm with screw terminals and option for bracket mounting; marking printed in white on a dark-brown sleeve for polarity identification.
• RoHS Compliance — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Regeneration — Used in regenerative voltage circuits to absorb and release energy during rapid torque changes and braking events.
• General Inverters — Bulk energy storage and ripple smoothing for inverter DC-link stages in industrial drives and power conversion equipment.
• Voltage-doubler Rectifier Circuits — Provides charge storage and smoothing in rectifier topologies such as voltage doublers.
• Equipment in Fluctuating-Voltage Areas — Stabilizes DC rails where supply voltage varies, leveraging rated voltage and endurance characteristics.

Unique Advantages

• High ripple-handling capability: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies support switching and regenerative environments.
• Designed for high-speed charge–discharge: Endurance and charge–discharge testing credentials align with frequent energy transfer cycles in motor drives and inverters.
• Robust thermal and lifetime characteristics: 5000 hours at 85°C endurance rating provides a defined reliability baseline for industrial applications.
• Secure electrical connections: Screw terminal mounting enables strong, low-resistance bolted terminations suited to high-current assemblies.
• Predictable low-temperature behavior: Defined impedance ratio ensures performance stability down to −25°C.
• Regulatory compliance: RoHS compliance supports use in designs targeting regulatory conformity in applicable markets.
