• Robust Ripple Current Capability: 9.6 A at 120 Hz and 13.44 A at 10 kHz, enabling reliable handling of low- and high-frequency ripple in inverter and regenerative circuits.
• Screw Terminal Mounting: Radial can with screw terminals and bracket-mounted options for secure, low-impedance connections in power assemblies.
• Charge–Discharge Endurance: Qualified for repetitive charge–discharge cycling (50 million cycles at specified conditions), supporting high-speed charge/discharge loads.
• Leakage, Insulation & Voltage Proof: Leakage current specified as not more than 3√CV µA or 5 mA after 5 minutes (at 20 °C); insulation resistance >100 MΩ at DC 500 V; AC 2500 V dielectric proof for 1 minute between terminal and bracket.
• Compact High-Voltage Design: Marketed as higher-voltage and smaller-sized compared to the LNT series, offering space-saving advantages in high-voltage power modules.
• RoHS Compliant: Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Bulk energy storage and ripple filtering in inverter front-ends and DC link circuits for industrial drives.
