Key Features

• Capacitance and Tolerance — 33 µF nominal capacitance with tolerance of -20% to +20%, enabling predictable bulk energy storage and filtering behavior.
• High Rated Voltage — 400 V rated voltage for high-voltage power rails and DC link applications that require elevated voltage handling.
• Radial Lead, Compact Can — φ16 × 30.5 mm package with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole assemblies and hand or wave soldering processes.
• Wide Operating Temperature — Specified for -40°C to +105°C operation, supporting applications across typical industrial and automotive temperature ranges.
• Long Endurance — 8000 hours rated life at 105°C, providing long-term stability under elevated temperature and DC bias.
• Ripple Current Capability — Low-frequency ripple current of 140 mA (120 Hz) and high-frequency ripple current of 224 mA (10 kHz), supporting smoothing and decoupling in switching supplies.
• Loss Characteristic — Dissipation factor (tan δ) of 0.25 measured at 20°C, 120 Hz under 400 V, allowing assessment of internal losses for thermal and efficiency calculations.
• Leakage Current — Specified leakage current of 628 µA, useful for standby and bias current budgeting.
• AEC‑Q200 Rated — Meets AEC‑Q200 designation as listed in the product specifications, aligning with certain automotive component expectations.
• Packaging — Supplied in bulk/no terminal forming or bag packing, suitable for low-volume production and prototyping workflows.
• Product Status — End Of Life status is indicated for this part number; verify availability and consider alternatives for new designs.

Typical Applications

• Switching Power Supplies — Bulk filtering and smoothing on high-voltage rails where a compact, high-voltage electrolytic is required.
• Automotive Power Electronics — Use in in-vehicle power systems and control modules where AEC‑Q200-rated components are specified.
• DC Link and Power Conversion — Energy storage and ripple suppression for converters and DC–DC stages operating at elevated DC bias.

Unique Advantages

• High-Voltage Capacity: 400 V rating enables deployment on higher-voltage DC rails without series stacking.
• Compact Through-Hole Form Factor: φ16 × 30.5 mm can with standard 7.5 mm lead spacing minimizes board area compared with larger cans while preserving through-hole robustness.
• Endurance at Elevated Temperature: 8000-hour life at 105°C supports reliable long-term operation in thermally demanding environments.
• Measured Ripple Performance: Specified ripple-current values at both low (120 Hz) and high (10 kHz) frequencies help predict heating and lifetime under real switching loads.
• Quantified Loss and Leakage: Published tan δ and leakage current values allow accurate thermal and leakage budgeting in power designs.
• Automotive-Grade Listing: Inclusion of AEC‑Q200 in the specifications supports selection for automotive-related assemblies where that qualification is required.
