Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20%.
• Low ESR — ESR of 17 mΩ measured at 20°C / 100 kHz, enabling efficient high-frequency performance.
• High Ripple Current — Low-frequency ripple current 400 mA (120 Hz) and high-frequency ripple current 4.0 A (300 kHz) for demanding power filtering tasks.
• Loss Characteristics — tan δ (dissipation factor) of 0.15 measured at 20°C / 120 Hz for predictable AC behavior.
• Leakage & Endurance — Leakage current specified at 660 µA and life/endurance of 2000 hours at 105°C under rated voltage.
• Robust Thermal Range — Rated for operation from −55°C to +105°C to suit a broad set of environments.
• Surface-Mount Can Package — φ8 × 11.7 mm radial can (SMD) optimized for PCB assembly; supplied in embossed carrier taping with moisture-proof packing.
• RoHS Compliant — Conforms to RoHS requirements.
• Reflow Compatibility — Series-level SMD type supports lead-free reflow soldering conditions up to a 260°C peak.

Typical Applications

• Power Supply Filtering — Low ESR (17 mΩ) and high ripple current (4.0 A at 300 kHz) make this capacitor suitable for bulk and output filtering in switching power supplies.
• DC-DC Converter Outputs — 330 µF capacitance and stable tan δ (0.15 at 120 Hz) support decoupling and voltage hold in high-frequency converter outputs.
• Embedded & Industrial Electronics — Wide operating range (−55°C to +105°C) and 2000 h life at 105°C provide reliable performance in industrial and embedded power circuits.
