Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) nominal capacitance with a 450 V rated voltage, suitable for extra-high voltage filtering and energy storage stages.
• Screw Terminal Package: Radial can with screw terminals for secure, low-resistance power connections in industrial assemblies.
• High Ripple Current Capability: Rated ripple current of 11.2 A at 120 Hz and 15.68 A at 100 kHz to support demanding switching and inverter loads.
• Long Endurance at Elevated Temperature: Specified for 20,000 hours of rated ripple life at +85°C, offering extended service life under continuous ripple stress.
• Operating Temperature Range: −25 °C to +85 °C, enabling use across a wide range of industrial ambient conditions.
• Polarized Design: Polar aluminum electrolytic capacitor with ±20% capacitance tolerance at 120 Hz, 20 °C.
• Leakage Current Specification: Leakage current after 5 minutes at 20 °C is not more than 3√(C·V) µA or 5 mA, whichever is smaller, providing predictable leakage behavior for power designs.
• RoHS Compliance & Safety Options: RoHS compliant (2011/65/EU,(EU)2015/863) with flame-retardant electrolyte versions available in the LNX series.

Typical Applications

• Industrial Power Supplies: Bulk filtering and smoothing in industrial AC/DC and DC/DC supplies where high-voltage filtering and long ripple life are required.
• Inverter Circuitry: Energy storage and ripple management on inverter DC links and power conversion stages subject to high switching stress.
• Extra‑High Voltage Power Stages: Filtering and decoupling in equipment that requires capacitors rated for hundreds of volts and high ripple currents.
• General Purpose Power Electronics: Use where a polarized, high-capacitance, high-voltage screw-terminal capacitor is needed for reliable long-term operation.

Unique Advantages

• High ripple endurance: Measured ripple ratings (11.2 A at 120 Hz, 15.68 A at 100 kHz) support heavy switching loads and reduce the need for parallel parts.
• Extended operational life: Rated for 20,000 hours at +85 °C under specified ripple current, minimizing maintenance and replacement frequency in long-running equipment.
• Extra‑high voltage capability: 450 V nominal rating enables use in high-voltage DC link and power conversion applications without up-rating multiple lower-voltage parts.
• Robust mechanical termination: Screw-terminal radial can construction provides secure electrical and mechanical connections for industrial environments.
• Predictable leakage behavior: Leakage limits defined as 3√(C·V) µA or 5 mA after 5 minutes at 20 °C help designers budget standby loss and protection schemes.
• Regulatory and safety options: RoHS compliance and availability of flame-retardant electrolyte variants support regulatory and fire-safety considerations.
