• Low Loss Characteristic — tan δ = 0.15 measured at 20°C, 120 Hz, supporting efficient AC performance in ripple‑laden environments.
• Ripple Current Capability — 515 mA at 120 Hz (low frequency) and 824 mA at 10 kHz (high frequency), enabling handling of both low‑ and high‑frequency ripple currents.
• Leakage Current — Specified leakage current of 1860 µA, measured after voltage application conditions consistent with product testing.
• High Endurance — Rated life of 8000 hours at 105°C, suitable for long‑running power systems.
• Operating Temperature — −40°C to +105°C, accommodating a wide range of environmental conditions.
• Mechanical & Mounting — Radial lead can form factor, dimensions φ18 × 40 mm, lead spacing 7.5 mm (±0.5 mm), and pressure relief vent for safety.
• Automotive Qualification — AEC‑Q200 rated, indicating suitability for applications requiring AEC‑Q200 level qualification.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to support different production workflows.

Typical Applications

• Switching Power Supplies — Bulk energy storage and smoothing for low‑impedance performance in power converters and regulator stages.
• Automotive Electronics — Use in vehicle electrical systems where AEC‑Q200 qualification and wide operating temperature are required.
