Key Features

• Electrical Performance — 1200 µF capacitance with ±20% tolerance and a rated voltage of 63 V; low dissipation factor (tanδ) of 0.08 measured at 20 °C, 120 Hz for stable AC behavior.
• High Ripple Handling — Low-frequency ripple current of 1.215 A (120 Hz) and high-frequency ripple current of 2.43 A (10 kHz) suitable for power-supply smoothing and converter outputs.
• Leakage and Stability — Specified leakage current of 756 µA and low-impedance construction for reliable performance under continuous bias.
• Reliability & Endurance — Rated for 5000 hours at 105 °C; meets endurance and shelf-life criteria outlined in the series datasheet.
• Automotive-Ready Qualification — AEC-Q200 rated, enabling use in designs that require component-level automotive qualification.
• Robust Mechanical & Packaging — Vibration-resistant construction and supplied in embossed carrier tape for automated surface-mount assembly.
• Compact Chip Form Factor — Physical size listed as φ18 × 21.5L with dimensional summary L: 2.15 × D: 1.8 cm and recommended surface-mount land size L: 1.83 × W: 1.83 cm.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Automotive Electronics — Power filtering and decoupling in vehicle control modules where AEC-Q200 qualification and extended temperature range are required.
• DC–DC Converters — Bulk and output filtering for converters that demand high ripple-current capability at both low and high frequencies.
• Industrial Power Supplies — Energy storage and smoothing in industrial regulators and power-conditioning circuits operating up to 105 °C.
• Embedded Systems — Local energy buffering and transient suppression on surface-mount PCBs using automated placement and tape-fed packaging.

Unique Advantages

• High ripple-current capability: Supports both low-frequency (1.215 A at 120 Hz) and high-frequency (2.43 A at 10 kHz) ripple currents for versatile power-stage use.
• Extended high-temperature endurance: 5000-hour rating at 105 °C provides predictable lifetime performance for thermally demanding designs.
• AEC-Q200 qualification: Explicitly qualified for applications requiring automotive-level component reliability.
• Low-loss operation: Tanδ of 0.08 (20 °C, 120 Hz) for reduced heating and improved AC stability in filtering roles.
• Surface-mount automation ready: Embossed carrier taping and vibration-resistant construction streamline high-volume PCB assembly and rugged deployment.
• Clear form-factor data: Documented mechanical dimensions and recommended land pattern simplify layout and mechanical integration.
