Key Features

• Capacitance and Voltage — 1.5 mF (1500 µF) nominal capacitance with a 500 V rated voltage; the LNU series supports rated voltages up to DC525 V.
• High Temperature & Long Life — Rated operating range −40°C to +105°C with a load life of 5000 hours at 105°C when subjected to rated ripple current.
• High Ripple Current — Ripple performance of 6.6 A at 120 Hz and 9.24 A at 10 kHz, suitable for high-frequency inverter and regenerative loads.
• Screw-Terminal Package — Radial can with screw terminals designed for secure, low-resistance connections; nominal bolt size for the series is M5 and brackets are supplied separately.
• Charge–Discharge Endurance — Specified endurance for charge–discharge behavior up to 50 million cycles (test condition: cycle 3 Hz with defined ΔV).
• Compact High-Voltage Design — High-voltage, smaller-sized construction compared with the LNT series for space-constrained high-voltage designs.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Used as a bulk/filter capacitor in inverter power supplies to handle high DC link voltages and ripple currents.
• Motor Drive & Servo Systems — Suited for regenerative voltage handling and high-frequency energy recovery in AC servomotors and drive inverters.
