Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance for power storage and bulk decoupling.
• High‑Temperature Endurance: Rated for −40°C to +125°C with a rated life of 5000 hours at 125°C, suitable for continuous high-temperature operation.
• Reliability & Qualification: AEC-Q200 qualified and RoHS compliant, reflecting suitability for regulated, safety‑conscious designs.
• Ripple Performance: Low-frequency ripple current 830.8 mA at 120 Hz and high-frequency ripple current 1.24 A at 100 kHz to handle AC stress on DC rails.
• Low Impedance & Loss: Impedance of 180 mΩ and tangent of loss angle (tan δ) of 0.08 measured at 20°C, 120 Hz, supporting efficient energy delivery.
• Leakage Current: Specified leakage current of 528 µA for predictable standby characteristics after application of rated voltage.
• Package & Mechanical: Radial-lead can package with 5 mm lead spacing (±0.5 mm), size φ12.5 × 25 mm (L: 2.5 cm × D: 1.25 cm), and bulk/bag packing options for high-volume assembly.

Typical Applications

• Automotive Electronics: Designed for in-vehicle electronics where +125°C endurance, AEC-Q200 qualification, and long life are required.
• Power Supply Filtering: Bulk energy storage and ripple handling on high-voltage rails using the 220 µF / 80 V rating and specified ripple currents.
• Heavy‑Duty Embedded Systems: Systems that demand stable capacitance and low impedance across wide temperature ranges and prolonged operation.

Unique Advantages

• High-Temperature Capability: Continuous operation to +125°C with a 5000-hour rated life at that temperature reduces risk in hot environments.
• AEC-Q200 Qualified: Explicit qualification for automotive-grade applications supports deployment in regulated vehicle electronics.
• Measured Ripple Performance: Published low- and high-frequency ripple current ratings (830.8 mA at 120 Hz, 1.24 A at 100 kHz) provide predictable behavior under AC stress.
• Low Loss and Low Impedance: 0.08 tan δ and 180 mΩ impedance at specified conditions help maintain efficiency and stable voltage rails.
• Compact Radial Form Factor: φ12.5 × 25 mm can with 5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• RoHS Compliant: Conforms to RoHS requirements for environmentally regulated production and end products.
