Key Features

• High Voltage Rating — Rated for 450 V, enabling use in high-voltage circuits where robust DC bias capability is required.
• High-Temperature Endurance — Specified operating temperature range of -25°C to 125°C with a rated lifetime of 2000 hours at 125°C for this part.
• Automotive-Grade Qualification — AEC‑Q200 qualification for suitability in designs requiring automotive-grade component qualification.
• Low and High Frequency Ripple Handling — Low-frequency ripple current of 154 mA (120 Hz) and high-frequency ripple current of 277.2 mA (100 kHz) to handle ripple across a wide frequency range.
• Electrical Characteristics — 22 µF capacitance with ±20% tolerance and a dissipation factor (tan δ) of 0.24 measured at 120 Hz, 20°C.
• Leakage Current — Specified leakage current of 496 µA after rated voltage application at 20°C.
• Radial Lead Package — Compact φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB insertion; available in bulk or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive electronics — Intended for automotive electronic systems that require high-voltage components with elevated-temperature endurance, leveraging the part's AEC‑Q200 qualification and +125°C rating.
• High-voltage power modules — Applicable where a 450 V rated electrolytic capacitor is needed for energy storage or smoothing under thermal stress.
• Elevated-temperature environments — Suited to designs that must maintain capacitor performance at temperatures up to 125°C with specified load-life characteristics.

Unique Advantages

• High-voltage capability: 450 V rating supports designs that operate at elevated DC voltages without requiring parallel stacking of lower-voltage components.
