LQR2V472MSEHBN

The LQR2V472MSEHBN is a screw‑terminal aluminum electrolytic capacitor designed for power electronics applications requiring robust high‑frequency charge/discharge performance. As part of the Nichicon LQR series, this radial can capacitor offers 4.7 mF (4700 µF) capacitance at a 350 V rating and an operating temperature range from −25 °C to 85 °C.

Engineered for use in AC servomotor drives, general inverters and equipment exposed to fluctuating voltages, the LQR2V472MSEHBN delivers endurance and ripple handling suited to regenerative and voltage‑doubler rectifier circuits, while meeting RoHS requirements.

Key Features

• Capacitance & Tolerance — 4.7 mF (4700 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• Voltage Rating — Rated voltage of 350 V for high‑voltage power applications.
• High‑frequency Ripple Handling — Ripple current capability of 16.4 A at 120 Hz and 22.96 A at 10 kHz for demanding regenerative or switching environments.
• Charge/Discharge Endurance — Specified endurance for charge/discharge behavior: tested for 20 million cycles with ΔV = rated voltage × 0.3 at 3 Hz, with performance limits on capacitance, tan δ and leakage current.
• Thermal Endurance — Rated for 5000 hours at 85 °C under DC bias plus rated ripple current; after recovery to 20 °C, capacitance and leakage remain within specified limits.
• Operating Temperature Range — −25 °C to +85 °C to support a wide range of industrial environments.
• Mounting & Package — Screw terminal, radial can package for secure bolted connections in power assemblies.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is ≤ 3√V (µA) or 5 mA, whichever is smaller (at 20 °C).
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Drives — Supports high‑frequency regenerative voltages and rapid charge/discharge cycles in motor drive DC bus and energy recovery circuits.
• General Inverters — Serves as DC link/filter capacitance in inverter topologies where voltage fluctuation and ripple are present.
• Voltage Doubler Rectifier Circuits — Suitable for rectifier circuits including voltage doubler configurations where stable high‑voltage capacitance is required.
• Equipment in Fluctuating Voltage Environments — Provides robust capacitance and endurance for installations subject to varying supply conditions and transient events.

Unique Advantages

• High ripple capacity at switching and high frequency: Specified ripple currents at 120 Hz and 10 kHz enable reliable operation in regenerative and switching power systems.
• Screw‑terminal robustness: Radial can with screw terminals provides secure bolted connections for high‑current DC bus installations.
• Proven endurance under thermal and electrical stress: 5000 hours at 85 °C endurance rating plus 20 million charge/discharge cycles provide predictable long‑term behavior in demanding applications.
• Wide operating temperature range: −25 °C to 85 °C supports diverse industrial environments without compromising specified electrical characteristics.
• Measured leakage current limits: Defined leakage current formula gives clear expectations for initial insulation performance after application of rated voltage.
• RoHS‑compliant: Meets current RoHS directive requirements for restricted substances.
