Key Features

• Capacitance & Tolerance — 3.3 µF nominal with tolerance of -20% to +20% for predictable performance at rated conditions.
• High Voltage Rating — Rated for 450 V operation, suitable for high-voltage input and filter circuits.
• Low-loss Behavior (tan δ) — tanδ (DF) = 0.25, measured at 20°C and 120 Hz, helping minimize dissipation in AC conditions.
• Ripple Current Handling — Low-frequency ripple current 41 mA (120 Hz) and high-frequency ripple current 65.6 mA (10 kHz) to support switching environments.
• Leakage Current — Specified leakage current 159.4 µA after rated voltage application, enabling predictable bias behavior.
• Endurance — 7000 hours at 105°C, providing long-term stability under elevated temperature stress.
• Temperature Range — Rated for operation from -25°C to 105°C to cover a wide range of ambient conditions.
• Package & Mounting — Radial lead, can-style package with size φ12.5 × 20L (Diameter 1.25 cm × Length 2 cm) and 5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• AEC Qualification — AEC-Q200 rated, indicating suitability for automotive electronics development and qualifying processes.

Typical Applications

• Switching Power Supplies — Input/output filtering and bulk decoupling where low impedance and reliable high-voltage performance are required.
• Automotive Electronic Modules — Power-conditioning and ripple suppression in automotive electronics, leveraging the AEC-Q200 rating and elevated-temperature endurance.
• High-Voltage Power Filters — Filtering and stabilization in high-voltage DC circuits that require compact radial-lead capacitors with defined leakage and ripple specs.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power stages and input filters without requiring multiple smaller capacitors in series.
• Compact radial can: φ12.5 × 20L footprint with 5 mm lead spacing provides a small, serviceable form factor for through-hole assemblies.
• Long elevated-temperature life: 7000 hours at 105°C supports sustained operation in thermally demanding environments.
• Measured low-loss behavior: tanδ = 0.25 at 20°C/120 Hz reduces dissipation and supports stable AC performance.
• Defined ripple handling: Specified ripple currents at 120 Hz and 10 kHz let designers size capacitance and cooling for switching loads with clarity.
• AEC-Q200 rated: Qualification aligned with automotive development workflows for modules intended for vehicle electronics.
