Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance.
• Low ESR — ESR of 15 mΩ measured at 20°C and 100 kHz, supporting low-loss operation in high-frequency environments.
• High Ripple Current — Low-frequency ripple current 2.25 A (120 Hz) and high-frequency ripple current 4.5 A (100 kHz) for robust smoothing and decoupling.
• Long Endurance — Endurance rated at 4000 hours at 125°C with defined post-test limits for capacitance, tan δ and ESR.
• Wide Temperature Range — Operates from −55°C to +125°C to handle elevated and sub-zero environments.
• Surface-Mount Chip Package — Chip-type SMD (radial can) package, size φ10 × 16L and recommended land size L: 1.03 × W: 1.03 cm, optimized for PCB mounting.
• AEC‑Q200 Qualified — Rated for automotive-grade reliability testing and applications that demand defined qualification standards.
• Lead‑Free Reflow Compatible — Meets lead‑free reflow soldering conditions with peak surface temperatures up to 260°C.
• Low Leakage — Specified leakage current of 405 µA after standard conditioning.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Automotive Electronics — Suitable for in-vehicle power systems and control modules where AEC‑Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering — Low ESR and high ripple-current ratings make the part effective for bulk smoothing and output filtering in DC‑DC converters and regulators.
• High-Reliability Industrial Power — Long life at elevated temperature and stable ESR after endurance testing support reliable operation in industrial power subsystems.

Unique Advantages

• High ripple-current capability: 4.5 A at 100 kHz and 2.25 A at 120 Hz reduce temperature rise under ripple loading, enabling more compact power designs.
• Low ESR for efficient power handling: 15 mΩ ESR at 100 kHz minimizes losses and improves transient response in filtering applications.
• Long-term thermal reliability: 4000 hours endurance at 125°C supports sustained operation in high-temperature environments.
• Automotive-grade qualification: AEC‑Q200 rating indicates the part meets defined automotive reliability test criteria.
• Reflow-friendly SMD form factor: Chip-type package and lead‑free reflow compatibility up to 260°C simplify assembly in modern manufacturing flows.
• Regulatory compliance: RoHS compliance supports use in regulated markets.
