Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 10 V rated voltage and a capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Long-Life High-Temperature Endurance — Rated for 5000 hours at +105°C; endurance limits: capacitance change within ±30%, tan δ up to 300% of initial specified value, and leakage current within initial specified limits after life test.
• Temperature Range — Operates across a category temperature range of −40°C to +105°C.
• Ripple Current Handling — Specified ripple currents of 238 mA at 120 Hz and 357 mA at 10 kHz, suitable for applications with AC ripple stress within these levels.
• Leakage Current Specification — After 2 minutes at rated voltage and 20°C, leakage current is ≤0.01 C·V or 3 µA, whichever is greater.
• Package & Mounting — Chip-type radial can SMD package designed for surface mounting on high-density PC boards; case dimensions L: 1 × D: 1 cm and recommended land size L: 1.03 × W: 1.03 cm.
• Standards & Compliance — AEC-Q200 qualified and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Construction — Polarized electrolytic capacitor suitable where polarity-aware placement is acceptable.

Typical Applications

• Automotive Electronic Modules — AEC-Q200 qualification and 5000-hour life at +105°C make this capacitor suitable for automotive electronics that require temperature durability and reliability.
• High-Density PCB Assemblies — Chip-type SMD design is optimized for surface mounting on compact, high-density printed circuit boards.
• Elevated-Temperature Systems — Long-life assurance at +105°C supports use in electronic systems that operate continuously at elevated temperatures.

Unique Advantages

• Long High-Temperature Endurance: 5000 hours at +105°C provides predictable aging characteristics for designs exposed to sustained elevated temperatures.
• AEC-Q200 Qualified: Qualification for AEC-Q200 supports selection for automotive-grade designs that require component-level reliability verification.
• Compact SMD Chip Package: Small L: 1 × D: 1 cm footprint and defined land size (1.03 × 1.03 cm) simplify layout on high-density PCBs.
• Measured Ripple Ratings: Published ripple current values at 120 Hz and 10 kHz allow designers to size the capacitor for expected AC stress conditions.
• RoHS Compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863), supporting regulatory and environmental requirements.
