Key Features

• Capacitance & Voltage — 1200 µF rated capacitance with ±20% tolerance at 120 Hz, 20°C, and a rated voltage of 63 V.
• Low Impedance Performance — Maximum impedance of 0.054 Ω at 20°C/100 kHz and tan δ of 0.08 (measured at 120 Hz, 20°C), suitable where low AC impedance is required.
• High Ripple Current — Rated ripple current of 2430 mArms at 105°C/100 kHz and 1.215 A at 120 Hz for handling significant AC stress.
• Thermal & Endurance — Wide operating temperature range from -55°C to +105°C and endurance specification of 5000 hours at 105°C.
• Reliability & Compliance — AEC-Q200 rating noted in specifications and RoHS compliant.
• Package & Assembly — Surface-mount radial can with case size φ18 × 21.5 mm (dimensions L: 2.15 × D: 1.8 cm) and supplied in embossed carrier taping for automatic mounting.
• Leakage & Loss Characteristics — Specified leakage current of 756 µA at 20°C after 2 minutes and a maximum tan δ consistent with performance at the rated voltage.

Typical Applications

• Automotive power electronics — AEC-Q200 qualification, 63 V rating and 5000 h endurance at 105°C make this capacitor suitable for automotive power modules and related systems requiring elevated temperature reliability.
• High-temperature power supplies — The -55°C to +105°C operating range and long endurance support use in power supplies and converters exposed to sustained heat.
• Surface-mount bulk decoupling — Compact φ18 × 21.5 mm SMD package and embossed carrier taping enable automated placement for bulk energy storage and decoupling on densely populated PCBs.

Unique Advantages

• High capacitance in a compact SMD form: 1200 µF in a φ18 × 21.5 mm package provides substantial energy storage while supporting surface-mount assembly.
• Low impedance across frequency: 0.054 Ω maximum at 100 kHz and tan δ of 0.08 help minimize voltage ripple and losses in AC-stressed circuits.
• Robust thermal endurance: Rated for 5000 hours at 105°C, enabling reliable operation in elevated-temperature environments.
• High ripple handling: 2430 mArms at 105°C/100 kHz and 1.215 A at 120 Hz provide strong performance for applications with significant ripple currents.
• Automated assembly ready: Surface-mount radial-can package supplied in embossed carrier taping simplifies pick-and-place integration.
• Industry-focused qualification and compliance: AEC-Q200 listing and RoHS compliance support use in regulated product programs.
