• Dissipation Factor (tan δ): 0.2 (measured at 20°C, 120 Hz) — Characterized loss for AC performance planning.
• Leakage Current: 758 µA — Measured leakage for power budgeting and standby current calculations.
• Long Endurance: 8000 hours at 105°C — Specified life for high-temperature continuous operation.
• Temperature Range: −40°C to +105°C — Suitable for wide operating temperature envelopes.
• Package & Mounting: Radial lead can, size φ20 × 31 mm with 10 mm lead spacing (±0.5 mm) — Compact through-hole footprint for board-level power stages.
• Packaging Options: Bulk (no terminal forming) or bag packing — Options for production handling and assembly.
• Qualification: AEC-Q200 listed in specifications — Supports use where AEC-Q200 qualification is required.

Typical Applications

• Switching Power Supplies: Low-impedance design and specified ripple currents make the capacitor well-suited for bulk smoothing and decoupling in switching regulators and power modules.
• Automotive Power Systems: AEC-Q200-listed construction and 8000-hour endurance at 105°C support use in automotive power electronics and on-vehicle power subsystems.
• Industrial Power Conversion: High 350 V rating and long life allow use in industrial DC-DC converters, inverters, and other power-conditioning equipment.

Unique Advantages

• High-voltage capability: 350 V rating enables use in higher-voltage DC bus and energy-storage applications without series stacking.
• Extended lifetime at elevated temperature: 8000 hours at 105°C provides predictable longevity for continuous high-temperature operation.
• Broad ripple handling: Specified ripple currents at 120 Hz and 10 kHz ensure the part can handle both low- and high-frequency AC stress typical of switching environments.
• Compact radial package: φ20 × 31 mm can-style radial package with 10 mm lead spacing offers a small footprint for through-hole power designs.
• Measured electrical characteristics: Defined tan δ (0.2) and leakage current (758 µA) give clear parameters for circuit design and verification.
• Automotive-qualified passive rating: Inclusion of AEC-Q200 in specifications supports design choices where that qualification is a requirement.
