Key Features

• Electrical Performance — 330 µF capacitance at 16 V with ±20% tolerance and a tanδ of 0.20 (max) measured at 20°C, 120 Hz, providing predictable AC behavior for decoupling and bulk energy storage.
• Ripple Handling — Rated ripple current of 290 mA at 105°C/120 Hz and 435 mA at 10 kHz, enabling reliable smoothing under typical power-supply ripple conditions.
• Low Leakage — Specified leakage current of 52.8 µA for controlled standby currents in energy‑sensitive circuits.
• Long Life Endurance — 5000 hours rated life at 105°C, designed for extended service in elevated temperature applications.
• Temperature Range — Operates from −55°C to +105°C to cover a wide set of environmental conditions.
• Package & Mounting — Chip-type, radial can SMD (φ10 × 10 mm) optimized for surface mounting on high-density PCBs; supplied in embossed carrier taping for automated assembly.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, reflecting suitability for stringent reliability requirements.

Typical Applications

• Automotive electronics — Bulk storage and filtering on high-density surface-mount PCBs used in automotive electronic modules where AEC‑Q200 qualification and long life are required.
• Power supply filtering — Smoothing and decoupling in DC‑DC converters and voltage regulators that need high capacitance and defined ripple performance.
• Industrial control — Energy buffering and noise suppression in control boards exposed to wide temperature swings and extended duty cycles.

Unique Advantages

• High capacitance in compact SMD form — 330 µF in a φ10 × 10 mm package reduces board area compared with through-hole equivalents while supporting surface-mount assembly.
• Endurance for elevated temperatures — 5000 hours at 105°C provides predictable lifetime for designs operating in sustained high-temperature environments.
• Defined ripple and loss characteristics — Specified ripple current (290 mA @ 120 Hz / 105°C; 435 mA @ 10 kHz) and tanδ (0.20 @ 16 V, 120 Hz) help designers size capacitors for stable power performance.
• Controlled leakage — Low leakage current (52.8 µA) helps maintain system standby behavior and predictable bias conditions.
• Surface-mount readiness — Embossed carrier taping and chip-type SMD construction streamline pick-and-place assembly on high-density PCBs.
• Standards and environmental compliance — AEC‑Q200 qualification and RoHS compliance support deployment in regulated and reliability-focused programs.
