Targeted for demanding power applications, the part provides 330 µF capacitance at a 25 V rating, AEC-Q200 qualification, and operational capability across −55 °C to 105 °C with a specified endurance of 5000 hours at 105 °C for the applicable size.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance at 25 V, with tolerance −20% to +20% for predictable bulk energy storage.
• Low Impedance Chip Type: Chip-type construction optimized for low impedance and measured tangent of loss angle (tan δ) of 0.14 at 20 °C, 120 Hz (25 V).
• Ripple Current Performance: Rated low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 600 mA (10 kHz), supporting smoothing and decoupling in power circuits.
• Thermal and Endurance Ratings: Operating temperature range −55 °C to 105 °C with an endurance rating of 5000 hours at 105 °C for the applicable size, enabling sustained performance under elevated temperature stress.
• Automotive-Grade Qualification: AEC-Q200 rating and RoHS compliance for use in regulated automotive and industrial manufacturing environments.
• Compact SMD Package: φ8 × 10L can in a surface-mount radial package with recommended land size 8.3 mm × 8.3 mm, supplied in embossed carrier taping for automated pick-and-place.
• Leakage and Stability: Specified leakage current of 82.5 µA and designed stability across low-temperature impedance ratios per the UCD series characteristics.

Typical Applications

• Automotive Power Modules: Suited for power smoothing and decoupling in automotive control modules where AEC‑Q200 qualification and high-temperature endurance are required.
• DC–DC Converters: Provides bulk capacitance and ripple handling for input/output filtering in switching regulators and power supply subsystems.
• High-Density PCBs: Designed for surface mounting on high-density boards and automatic assembly, enabling compact power delivery layouts.
• Embedded and Industrial Electronics: Useful for general power decoupling and energy storage in embedded controllers and industrial equipment operating across −55 °C to 105 °C.

Unique Advantages

• Low-impedance performance: Chip-type construction and measured tan δ support effective AC performance for ripple suppression and stable operation under load.
• Automotive-capable reliability: AEC‑Q200 qualification and 5000-hour endurance at 105 °C for the applicable size demonstrate suitability for long-life, high-temperature applications.
• Clear ripple-handling spec: Separate low- and high-frequency ripple current ratings (300 mA at 120 Hz and 600 mA at 10 kHz) provide designers with explicit performance expectations across frequency.
• Surface-mount, assembly-friendly package: φ8 × 10L SMD can and embossed carrier taping streamline placement on automated production lines for high-volume manufacturing.
• Wide operating range: −55 °C to 105 °C specification supports deployments across harsh environmental conditions without ambiguity.
• RoHS compliant: Environmentally compliant materials and manufacturing for regulated supply chains.
