• Package and Mounting: Radial lead can package, size φ10 × 20 mm with 5 mm lead spacing, supplied in bulk or bag packing for flexible assembly.
• Standards & Compliance: AEC‑Q200 qualified and RoHS compliant, addressing industry reliability and environmental requirements.

Typical Applications

• Automotive power modules: Smoothing and decoupling in vehicle electronic modules where AEC‑Q200 qualification, 16 V rating and 5000 h high-temperature endurance are required.
• Power supply filtering: Bulk decoupling and hold-up in DC power rails, leveraging 680 µF capacitance and low impedance for reduced ripple and improved regulation.
• Motor control and drives: Energy buffering and ripple suppression in motor driver circuits that operate over wide temperatures and demand durable components.
• Industrial electronics: Filtering and transient suppression in controllers and power converters that require long life at elevated temperatures.

Unique Advantages

• Verified AEC‑Q200 Reliability: Qualification to AEC‑Q200 provides documented suitability for automotive-grade electronics and demanding environments.
• Long High‑Temperature Life: 5000 hours at +105°C under rated conditions reduces maintenance and replacement frequency in high‑temperature installations.
• Strong Ripple Handling: High-frequency ripple current rating of 880 mA and low-frequency rating of 598.4 mA support robust performance under continuous AC stress.
• Predictable Electrical Behavior: Low impedance (65 mΩ) and defined tan δ (0.16 at 20°C, 120 Hz) make it easier to design stable power systems and predict thermal/ripple losses.
• Compact Radial Form Factor: φ10 × 20 mm radial can with 5 mm lead spacing fits space-constrained boards while providing substantial capacitance.
• Regulatory Compliance: RoHS-compliant construction supports environmentally conscious designs and supply-chain requirements.
