Key Features

• Aluminum Electrolytic, Screw-Terminal Construction Heavy-duty screw terminals and radial can packaging provide a secure electrical and mechanical connection for high-current systems.
• High Capacitance and Voltage 12,000 µF capacitance at a 450 V rating offers substantial energy storage for DC link and smoothing applications.
• High Ripple Current Handling Rated for 38.20 A at 120 Hz (low frequency) and 53.48 A at 100 kHz (high frequency), supporting heavy ripple and fast charge–discharge cycles.
• Long Life Endurance Load-life rated to 5,000 hours at 85 °C with D.C. bias plus rated ripple current applied, meeting the LNC series endurance specifications.
• Wide Operating Temperature Range Specified for −40 °C to +85 °C operation to cover a broad range of industrial environments.
• Leakage Current Initial leakage current specified up to 5,000 µA (5 mA) per the product data.
• Compact High-Energy Form Factor Physical dimensions φ90 × 185 L (18.5 cm × 9 cm) provide high capacitance in a controllable footprint for panel or bracket mounting.
• RoHS Compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Ideal for inverter circuitry and DC link smoothing where sustained ripple current capability is required.
