Key Features

• Capacitance & Tolerance: 10,000 µF nominal with ±20% tolerance (120 Hz, 20°C), providing substantial bulk energy storage for power rails.
• Voltage Rating: 16 V rated voltage suitable for low-voltage power supply filtering and energy buffering.
• Wide Temperature Range: Rated for −55°C to +105°C to maintain functionality across wide ambient conditions.
• Endurance: 2000 hours at 105°C life rating, with specified limits on capacitance change, dissipation factor, and leakage after the endurance test.
• Ripple Current Capability: Low-frequency ripple current 2.06 A at 120 Hz and high-frequency ripple current 2.369 A at 10 kHz for effective AC load handling.
• Leakage Current: Specified leakage current of 4800 µA (product value) for initial condition considerations in design.
• Package & Mounting: Radial lead can, size φ18 × 35.5 mm (L), lead spacing 7.5 mm ±0.5 mm; available in bulk (no terminal forming) or bag packing.
• Reliability Rating: AEC-Q200 listed in specifications for enhanced component qualification where specified.
• Polarized Device: Polarized electrolytic capacitor; observe polarity in assembly and circuit design.

Typical Applications

• High-grade Audio Equipment: Bulk capacitance for power supply smoothing and energy storage in audio devices that require stable low-frequency performance and long-term reliability.
• Power Supply Filtering: Large-capacitance filtering in low-voltage power rails where 16 V rating and high ripple current capability are needed.
• Industrial and Electronic Systems: General-purpose bulk energy storage in electronic assemblies operating across a wide temperature range (−55°C to +105°C).

Unique Advantages

• Substantial Bulk Capacitance: 10,000 µF provides significant energy reserve for smoothing and load transients in compact radial-can form.
• Temperature and Endurance Robustness: −55°C to +105°C range and 2000 h endurance at 105°C support long-term stability in harsh operating environments.
• High Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to account for both low- and high-frequency AC stresses.
• Qualified Reliability: AEC-Q200 listing in the product specifications signals enhanced quality controls useful for reliability-focused designs.
• Practical Packaging Options: Offered in bulk (no terminal forming) or bag packing to accommodate automated or manual assembly workflows.
