Engineered for demanding power electronics, this part is suited to power supply and ballast applications and is AEC‑Q200 qualified for use in automotive-related designs, offering extended endurance at elevated temperature.

Key Features

• Capacitance & Rated Voltage — 22 µF nominal capacitance with a 400 V rated voltage and tolerance of ±20%.
• High ripple current capability — Specified low-frequency ripple current of 275 mA at 120 Hz and high-frequency ripple current of 550 mA at 100 kHz, supporting robust filtering and smoothing in power circuits.
• Long lifetime at high temperature — Endurance specified for 12,000 hours at +105 °C under rated ripple and DC bias conditions.
• Low loss — Tangent of loss angle (tan δ) up to 0.24 measured at 20 °C, 120 Hz (rated voltage 400 V), supporting stable AC performance.
• Leakage current — Specified leakage current of 452 µA.
• Robust temperature range — Rated for operation from −40 °C to +105 °C to cover a wide range of ambient conditions.
• Package & mounting — Radial lead, can-style package (φ10 × 30.5 mm), lead spacing 5.0 mm, supplied in bulk or bag packing (no terminal forming).
• Quality & compliance — AEC‑Q200 qualified and RoHS compliant, supporting reliability and regulatory requirements for regulated markets.

Typical Applications

• Power supplies — Bulk filtering and smoothing in high-voltage DC rails where 400 V rating and high ripple tolerance are required.
• Ballasts — AC/DC ballast circuits that demand sustained ripple handling and long operating life at elevated temperature.
• Automotive power electronics — Energy storage and smoothing in automotive subsystems, leveraging AEC‑Q200 qualification and extended endurance at +105 °C.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without series stacking.
• Designed for sustained ripple: Clear low- and high-frequency ripple current specifications (275 mA at 120 Hz, 550 mA at 100 kHz) allow designers to size capacitors with confidence.
• Long operational life: 12,000-hour endurance at 105 °C supports reliable service in thermally stressful environments.
• Automotive-grade qualification: AEC‑Q200 status provides an added level of process and part qualification for vehicle-related applications.
• Compact radial form factor: φ10 × 30.5 mm can with 5.0 mm lead spacing offers a space-efficient solution for through-hole boards and assemblies.
• Regulatory compliance: RoHS compliant for global regulatory alignment.
