Key Features

• High Voltage Rating — Rated up to DC 525 V to support industrial inverter and regenerative circuits.
• Capacitance — 5.6 mF nominal capacitance with ±20% tolerance (120 Hz, 20°C) for bulk energy storage and smoothing.
• High‑Temperature Endurance — Specified load life of 5000 hours at 105°C with application of rated ripple current; capacitance, tan δ and leakage current limits defined by the endurance test.
• High Ripple Current Handling — 17.5 A at 120 Hz and 24.5 A at 10 kHz, enabling performance in high‑frequency and high‑ripple environments.
• Thermal Range — Operating temperature range from −40°C to +105°C for wide ambient tolerance in industrial settings.
• Screw Terminal Mounting — Radial can with screw terminals for robust electrical and mechanical connections in power assemblies.
• Reliability & Safety — Insulation resistance >100 MΩ at DC 500 V (terminal to bracket) and withstands AC 2500 V for 1 minute between terminal and bracket; leakage current limits specified (≤3√CV μA or 5 mA after 5 minutes at 20°C).
• Cycling Endurance — Meets specified characteristics after 50 million charge/discharge cycles (3 Hz), demonstrating suitability for repetitive regenerative applications.
• Smaller Footprint vs. LNT — LNU series offers reduced size compared with LNT series while maintaining high‑voltage capability.

Typical Applications

• Industrial Power Supplies — Energy storage and smoothing in inverter front‑ends and high‑voltage DC rails for industrial equipment.
