Key Features

• Construction – Conductive Polymer Hybrid: Chip-type aluminum electrolytic design using conductive polymer hybrid technology for improved reliability at elevated temperatures.
• High Temperature Rating: Rated operating range from -55°C to +135°C with a long-life specification of 4000 hours at 135°C.
• Capacitance & Voltage: 330 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR & High Ripple Current: ESR specified at 16 mΩ (100 kHz, 20°C) with ripple current ratings of 3.5 A at 100 kHz and 525 mA at 120 Hz.
• Reliability & Qualification: AEC-Q200 qualified and RoHS compliant; endurance limits include capacitance change within ±30% and ESR/tan δ within 200% after endurance testing.
• Surface-Mount Can Package: Radial, can-style SMD package with overall dimensions approximately 1 cm × 1 cm and recommended land size 1.03 cm × 1.03 cm for PCB layout.
• Endurance & Shelf Life: Endurance performance verified for 4000 hours at high temperature and shelf-life stability tests (1000 hours at 135°C) per datasheet conditions.

Typical Applications

• Automotive Electronics: Intended for automotive systems requiring high-temperature operation and long-term reliability; AEC-Q200 qualification and 135°C endurance support use in temperature-challenging locations.
• Power Conversion and Regulation: Low ESR and high ripple-current capability make this part suitable for bulk decoupling and smoothing in power converters and DC–DC regulation stages.
• Compact High-Temperature SMD Designs: Small surface-mount can footprint (≈1 × 1 cm) enables space-efficient board layouts where elevated temperature endurance is required.

Unique Advantages

• High-temperature endurance: Rated for continuous operation up to 135°C with a specified 4000-hour life at that temperature, reducing the risk of premature aging in hot environments.
• Efficient power handling: Low ESR (16 mΩ at 100 kHz) and high ripple-current ratings reduce losses and improve thermal performance in high-power circuits.
• Qualified for demanding applications: AEC-Q200 qualification and RoHS compliance provide documented reliability for regulated and safety-conscious designs.
• Compact SMD can format: Surface-mount radial can package and small footprint enable integration into space-constrained assemblies without sacrificing performance.
• Documented endurance behavior: Clear endurance and damp-heat performance limits (capacitance, tan δ, ESR, leakage) help predict in-system performance over long service intervals.
