LQR2V153MSEJBB

The LQR2V153MSEJBB is a screw‑terminal aluminum electrolytic capacitor rated at 15,000 µF and 350 V, designed for high‑speed charge/discharge and heavy energy storage. Its radial can with screw terminals and polarized construction supports high ripple currents and robust electrical connections for industrial power systems.

Typical use cases include inverter and servo regenerative circuits, equipment subject to fluctuating voltages, and rectifier stages such as voltage doubler configurations. The device is RoHS compliant and specified for continuous operation across an operating temperature range of -25 °C to 85 °C.

Key Features

• High Capacitance & Voltage: 15,000 µF nominal capacitance at a 350 V rated voltage for substantial energy storage and smoothing in power systems.
• Mounting & Package: Screw terminal radial can (polarized) provides secure, low‑impedance connections for high current applications.
• High Ripple Handling: Rated ripple current of 40.5 A at 120 Hz and 56.7 A at 10 kHz, supporting demanding AC and regenerative load conditions.
• Temperature & Endurance: Operating range -25 °C to 85 °C with an endurance rating of 5,000 hours at 85 °C under rated conditions.
• Charge–Discharge Durability: Designed to withstand extensive charge/discharge cycling (series endurance specification: 20 million cycles at specified ΔV and cycle rate).
• Leakage & Stability: Leakage current specification follows series guidance (after 5 minutes leakage ≤ 3√V µA or 5 mA, whichever is smaller) and low‑temperature impedance stability (Z at -25 °C up to 8× Z at +20 °C).
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• AC servomotor regenerative systems: Stores and smooths high‑frequency regenerative voltage and supports rapid charge/discharge cycles in servo drive circuits.
• General inverters: Provides bulk energy storage and ripple absorption in inverter DC bus networks, improving stability during switching transients.
• Voltage fluctuating environments: Suited for equipment operating under variable mains or fluctuating supply conditions where robust smoothing and energy buffering are required.
• Rectifier / voltage doubler circuits: Used in rectifier stages to stabilize DC output and handle repeated charge/discharge events inherent to voltage doubler topologies.

Unique Advantages

• Large energy capacity: 15,000 µF at 350 V delivers substantial stored energy for DC bus stabilization and short‑term power demands.
• High ripple endurance: Elevated ripple current ratings at both low and high frequencies reduce heating and extend service life in high‑stress power applications.
• Robust mechanical connections: Screw terminal radial can construction ensures reliable, low‑resistance termination for heavy current paths.
• Long endurance at temperature: Specified 5,000 hours at 85 °C provides predictable lifetime performance for industrial environments.
• Charge/discharge resilience: Series endurance testing for millions of cycles indicates suitability for frequent regenerative and switching duty.
• Regulatory compliance: RoHS conformity simplifies regulatory acceptance in restricted‑substance environments.
