• High‑Temperature Long Life — Rated for continuous operation up to 105 °C with an endurance specification of 5000 hours under D.C. bias plus rated ripple current at 105 °C.
• Snap‑in Radial Can Package — Snap‑in terminal type in a radial can package for robust board mounting and mechanical stability in power assemblies.
• Ripple Current Performance — Specified ripple current of 1.33 A at 120 Hz and 1.902 A at 50 kHz for effective smoothing in power conversion circuits.
• Operating Temperature Range — −25 °C to +105 °C, enabling use across a wide range of industrial operating environments.
• Leakage and Loss Characteristics — Leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20 °C; tan δ limits and impedance behavior are specified in the LGX series datasheet.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Circuits — Bulk and smoothing capacitor for rectifier stages in general inverters, benefiting from 450 V rating and high‑temperature endurance.
• Switching Power Supplies — Bulk energy storage and output filtering in SMPS designs where high voltage handling and long ripple endurance at 105 °C are required.
