Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 450 V for DC bus energy storage in inverter and regenerative systems.
• High ripple-current capability — Rated ripple current of 9.9 A at 120 Hz and 13.86 A at 100 kHz to handle both low- and high-frequency ripple in power electronics.
• Screw terminal package — Radial can with screw terminals for secure, high-current connections and straightforward installation in power assemblies. Physical size: L 8 × D 5.1 cm.
• Wide operating temperature and endurance — Operates from −40 °C to +85 °C with a load life of 5000 hours at 85 °C under rated ripple conditions.
• Charge–discharge endurance — Designed to tolerate high-speed charge/discharge cycling; specified endurance includes performance after 50 million charge–discharge cycles at room temperature (ΔV = rated × 0.3, 3 Hz).
• Leakage and insulation characteristics — Leakage current specified as not more than 3√V (µA) or 5 mA (whichever smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V and AC voltage proof 2500 V for 1 minute between terminal and bracket.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — DC bus smoothing and energy buffering where sustained ripple handling and 450 V rating are required.
• AC servomotor drives — Supports high-frequency regenerative voltages and frequent charge–discharge events encountered in servo systems.
• General motor control and drive systems — Suitable for inverter-fed motor drives that demand compact, high-ripple capacitors for reliable DC link performance.
• High-frequency regenerative systems — Designed for applications with significant high-frequency ripple up to 100 kHz, leveraging its specified high-frequency ripple current rating.

Unique Advantages

• Compact high-ripple design: Smaller-sized construction with higher ripple capability compared to prior LNC series variants, enabling space-efficient DC bus designs.
• Extended operational life at elevated temperature: 5000-hour rated life at 85 °C under applied ripple current provides predictable longevity in industrial environments.
