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.
• Low Impedance Design — Chip-type, low-impedance construction optimized for ripple handling and transient response in power-supply circuits.
• High-Frequency & Low-Frequency Ripple Performance — Rated ripple currents of 300 mA at 120 Hz and 600 mA at 10 kHz, supporting both low- and high-frequency ripple filtering.
• Loss Characteristics — tanδ = 0.19 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for thermal and loss budgeting.
• Leakage Current — Specified leakage current of 33 µA, useful for predicting standby current and bias behavior.
• Automotive-Grade Reliability — AEC-Q200 rating and a 2000-hour endurance at 105°C (for φD ≤ 10 mm) for long-term operation in elevated-temperature environments.
• Wide Temperature Range — Operating range from -55°C to +105°C for compatibility with harsh ambient conditions.
• Compact Surface-Mount Package — φ6.3 × 7.7 mm can (L: 7.7 mm × D: 6.3 mm) with a recommended land size of 6.6 × 6.6 mm, supplied in embossed carrier tape for automated pick-and-place.
• Vibration Resistant — Designed with vibration resistance for reliable use in mechanically demanding environments.
• Regulatory — RoHS compliant.

Typical Applications

• Automotive Power Electronics — Suitable for smoothing and decoupling on low-voltage power rails in automotive control modules, supported by AEC-Q200 qualification and a wide temperature range.
• Embedded Power Supplies — Bulk energy storage and ripple filtering in compact, surface-mount DC–DC converters and regulators where space is constrained.
• High-Reliability Industrial Electronics — Filtering and decoupling in industrial control and monitoring systems that require extended endurance at elevated temperatures.
