LQR2G152MSEFBB

The LQR2G152MSEFBB is a screw-terminal aluminum electrolytic capacitor rated at 1500 µF and 400 V, designed for high-speed charge–discharge operation. Its robust screw-terminal can and radial mounting make it suitable for power electronics where secure connections and high ripple handling are required.

This capacitor is specifically suited for high-frequency regenerative voltage applications such as AC servomotors and general inverters, equipment operating in voltage-fluctuating environments, and rectifier circuits including voltage doublers. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 1.5 mF (1500 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing bulk energy storage for power-conversion circuits.
• High-speed charge–discharge — Engineered for rapid charge and discharge cycles and endurance of charge–discharge behavior tested to 20 million cycles at rated ΔV × 0.3 and 3 Hz.
• High ripple current handling — Rated ripple current of 7.5 A at 120 Hz and 10.5 A at 10 kHz to support both low- and high-frequency ripple environments.
• Mounting & package — Screw terminal, radial can design for secure, low-impedance connections in industrial power assemblies. Physical size: L: 8 × D: 5.1 cm; height seated max 3.15 inch.
• Temperature & endurance — Operating temperature range −25 °C to +85 °C with endurance specified as 5000 hours at 85 °C under DC bias plus rated ripple current.
• Leakage and reliability characteristics — Leakage current specification after 5 minutes follows the datasheet limit (≤ 3√V µA or 5 mA, whichever is smaller); tan δ and capacitance stability are defined for endurance and charge–discharge tests.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servomotor drives — Handles high-frequency regenerative voltages and rapid charge–discharge cycles commonly found in servo regenerative loops.
• General inverters — Acts as DC-link/bulk capacitance for inverters operating with fluctuating supply or regenerative conditions.
• Equipment in voltage-fluctuating areas — Stabilizes DC bus during supply disturbances and fluctuating line conditions.
• Rectifier/voltage-doubler circuits — Suitable for rectifier stages and voltage-doubler topologies requiring high-voltage bulk capacitance.

Unique Advantages

• Designed for rapid cycling: Proven endurance under high-frequency charge–discharge conditions (20 million cycles test) helps maintain performance in dynamic power systems.
• Wide ripple capability: Specified ripple current at both 120 Hz and 10 kHz supports designers working across switching and line-frequency domains.
• High-voltage bulk energy: 400 V rating with 1500 µF capacitance provides substantial energy storage for DC-link and regenerative applications.
• Industrial mounting reliability: Screw-terminal radial can package enables secure electrical and mechanical connections in power assemblies.
• Thermal endurance: Rated for continuous operation up to 85 °C with 5000-hour endurance under rated conditions for long-term reliability in elevated-temperature environments.
• Standards compliance: RoHS conformity ensures use in designs requiring regulatory compliance for restricted substances.
