Key Features

• Electrical Performance — 330 µF capacitance at 50 V with ±20% tolerance (measured at 120 Hz, 20°C), providing bulk energy storage and smoothing for power rails.
• Ripple Current Capability — Rated ripple current of 440 mA at 120 Hz and 660 mA at 10 kHz, supporting AC ripple filtering in power circuits.
• Temperature and Lifetime — Operating range from −55°C to 105°C with a rated endurance of 5000 hours at 105°C, enabling use in elevated-temperature environments.
• Reliability and Qualification — AEC-Q200 qualified and RoHS compliant, supporting designs that require automotive-grade screening and lead-free compliance.
• Package and Mounting — Chip-type radial can SMD package sized L: 2.1 × D: 1.25 cm with recommended land size L: 1.28 × W: 1.28 cm; intended for surface-mount assembly and automatic tape-fed pick-and-place.
• Polarized Construction — Polarized aluminum electrolytic design for applications requiring axial bulk capacitance in an SMD form factor.

Typical Applications

• Automotive Electronics — Use in vehicle electronic modules where AEC-Q200 qualification and elevated-temperature endurance are required for power smoothing and energy storage.
• Power Supply Filtering — Bulk decoupling and ripple suppression on high-density PC boards in power conversion and regulation stages.
• High-Density PCB Assemblies — Surface-mount chip form factor that supports automatic tape-fed mounting for compact, densely populated boards.

Unique Advantages

• High Capacitance in an SMD Chip — 330 µF enables significant bulk storage while maintaining a surface-mount chip footprint for space-constrained designs.
• Automated Assembly Ready — Compatible with carrier-tape fed pick-and-place processes to streamline manufacturing and reduce assembly time.
• Automotive-Grade Qualification — AEC-Q200 qualification provides an added level of component screening for reliability-sensitive applications.
• Wide Temperature Endurance — −55°C to 105°C operating range and 5000-hour life at 105°C support long-term operation in elevated temperatures.
• Measured Ripple Handling — Specified ripple current ratings at both low and high frequencies (120 Hz and 10 kHz) help designers select a capacitor matched to their ripple environment.
