Key Features

• Electrical Rating — 350 V rated voltage with 330 µF capacitance and capacitance tolerance of −20% to +20%.
• Low Loss / Low Impedance — tangent of loss angle (tan δ) specified as 0.2 measured at 20 °C, 120 Hz, supporting efficient energy storage and reduced heating.
• Ripple Current Capability — low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 256 mA (10 kHz), enabling use in switching power environments.
• Leakage Current — specified leakage current of 562 µA, expressed per the product data.
• High Endurance — rated endurance of 8000 hours at 105 °C under DC bias plus rated ripple current conditions.
• Compact Radial Package — φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm), supplied as bulk (no terminal forming) or bag-packed.
• Polarized, Through-Hole Form — radial lead mounting simplifies PCB implementation for through-hole designs.
• AEC-Q200 Rated — qualification present in the product data, supporting use in automotive-grade applications.

Typical Applications

• Switching Power Supplies — compact, low-impedance bulk capacitance for smoothing and energy storage in switch-mode power stages.
• Automotive Electronics — specified for automotive applications and supported by AEC-Q200 qualification for modules that require elevated reliability.
• High‑Voltage Power Rails — 350 V rating suits bulk filtering and energy buffering on high-voltage DC rails in power conversion equipment.

Unique Advantages

• High Voltage Capability: 350 V rating enables use on higher-voltage DC rails without series stacking.
• Long Operational Life: 8000 hours at 105 °C under rated conditions delivers predictable aging and maintenance planning for long-life systems.
• Frequency-Responsive Ripple Handling: Distinct low- and high-frequency ripple current specifications (160 mA at 120 Hz, 256 mA at 10 kHz) provide designers with explicit performance data across operating conditions.
• Compact Footprint: φ16 × 30.5 mm radial can offers high capacitance per package volume for space-constrained boards.
• Automotive-Grade Qualification: Inclusion of AEC-Q200 in the product data supports selection for automotive and other high-reliability applications.
