• Screw Terminal Mounting — Radial can package with screw terminals for secure, low-impedance connections in power assemblies.
• High Ripple Current — Rated ripple current of 9.9 A at 120 Hz and 13.86 A at 100 kHz to support heavy AC and high-frequency loading conditions.
• Wide Temperature Range — Operates from −40°C to +85°C to cover typical industrial ambient conditions.
• Extended Load Life — Load life specified as 5000 hours at 85°C under rated ripple current, supporting long-term operation in power electronics.
• Charge–Discharge Endurance — Characterized for 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz cycle) at room temperature, maintaining capacitance, tan δ, and leakage current within specified limits.
• Electrical Safety Parameters — Leakage current spec after 5 minutes: not more than 3√(V) µA or 5 mA (whichever is smaller) at 20°C. Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; AC 2500 V for 1 minute between terminal and bracket shows no abnormality.
• Polarized, Compact Package — Polarized aluminum electrolytic can in a smaller-sized LNC package (L: 8 × D: 5.1 cm) with a seated height max of 3.15 inch, offering space-efficient power filtering.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in inverter-based and industrial power supply designs where high voltage and high ripple handling are required.
• Inverter Circuits — DC link and bus capacitor for general inverters, supporting charge–discharge cycles and high-frequency ripple currents.
• AC Servomotor Regeneration — Suited for handling high-frequency regenerative voltages in AC servomotor drives and related motor control systems.
• High-Frequency Power Electronics — Applications that demand robust performance under high-speed charge–discharge conditions and elevated ripple currents.

Unique Advantages
