Designed for demanding environments, it combines a compact φ8 × 10 mm SMD can with a wide operating temperature range and AEC‑Q200 qualification for automotive use.

This part targets applications that need bulk capacitance, stable performance across −55°C to +105°C, and long-term endurance (2000 hours at 105°C), while fitting into compact surface-mount assemblies with embossed carrier taping packaging.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in low-voltage power rails.
• Electrical Losses — Tangent of loss angle (tan δ) of 0.19 measured at 20°C, 120 Hz, providing quantified loss performance for design verification.
• Leakage Current — Specified leakage current of 99 µA at the rated condition, suitable for designs that require controlled leakage behavior.
• Ripple Current Capability — Low-frequency ripple current of 296 mA at 120 Hz and high-frequency ripple current of 384.8 mA at 10 kHz to support AC stress on power rails.
• Temperature & Endurance — Operating range from −55°C to +105°C and endurance of 2000 hours at 105°C, supporting prolonged operation under elevated temperatures.
• Package & Mounting — φ8 × 10 mm radial can in an SMD configuration, surface-mount land recommendation 8.3 × 8.3 mm, and supplied in embossed carrier taping for pick-and-place assembly.
• Polarized Construction — Polarized electrolytic capacitor for correct-oriented DC applications.
• Automotive Rating — Rated to AEC‑Q200, meeting automotive electronic component qualification requirements.

Typical Applications

• Automotive electronics — Suited for automotive modules requiring an AEC‑Q200 qualified 10 V, 330 µF surface-mount capacitor with a wide temperature range.
• Power supply filtering — Provides bulk capacitance and ripple handling on low-voltage power rails in compact board layouts.
• Embedded systems — Fits space-constrained surface-mount assemblies that need stable capacitance from −55°C to +105°C and long-term endurance.

Unique Advantages

• AEC‑Q200 qualification: Provides a recognized automotive-grade qualification for designs targeting vehicle electronics.
