Key Features

• Core Electrical — 330 µF nominal capacitance with a rated voltage of 25 V and polarization as an aluminum electrolytic capacitor. Capacitance tolerance is ±20%.
• High-Temperature Endurance — Rated for 5000 hours of load life at 125 °C, enabling sustained operation under elevated thermal stress.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU and (EU)2015/863), supporting designs that require automotive-grade reliability and environmental compliance.
• Operating Range — Specified operating temperature from −55 °C to +125 °C for broad thermal capability in harsh environments.
• Ripple Performance — Rated ripple current of 502.5 mA at 120 Hz and 750 mA at 10 kHz, with frequency-dependent ripple characteristics available in the series data.
• Leakage & Loss — Leakage current specified as not more than 0.03CV (µA) after 1 minute at 20 °C; tan δ (loss factor) for 25 V is specified (max. 0.16 at 120 Hz, 20 °C).
• Surface-Mount, Vibration-Resistant Package — Chip-type SMD (radial can - SMD) package with compact dimensions: body L 13.5 mm × D 12.5 mm and seating/land recommendations provided for PCB layout.

Typical Applications

• Automotive electronics — Suited for vehicle electronics where heavy-duty service and high-temperature endurance are required.
