Key Features

• Electrical Performance — 270 µF capacitance at 25 V with tolerance −20% to +20%; tangent of loss angle (tanδ) 0.14 measured at 20°C, 120 Hz.
• Low ESR & High Ripple Capability — ESR 20 mΩ measured at 100 kHz, 20°C; high-frequency ripple current 2.0 A (100 kHz) and low-frequency ripple current 300 mA (120 Hz).
• Leakage Current — Specified leakage current 67.5 µA after rated-voltage application.
• High Temperature Endurance — Rated operating range −55°C to +135°C with endurance of 4,000 hours at 135°C under rated conditions.
• Package & Mounting — Surface-mount radial can (chip type) with physical size φ10 × 10L (1 cm × 1 cm) and recommended land size 1.03 × 1.03 cm; supplied in embossed carrier taping for automated placement.
• Reliability & Durability — AEC‑Q200 qualification and vibration-resistant construction for reliable operation in harsh environments.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling on power rails for control modules and power converters where AEC‑Q200 qualification and high-temperature endurance are required.
• High-reliability industrial systems — Energy storage and ripple filtering in industrial controllers and power subsystems operating across −55°C to +135°C.
• Embedded power supplies — Local decoupling and transient energy buffering in compact SMD power designs that need low ESR and high-frequency ripple handling.

Unique Advantages

• Low ESR for efficient filtering: 20 mΩ ESR at 100 kHz enables improved high-frequency decoupling and reduced power dissipation under ripple load.
• High ripple-current handling: 2.0 A (100 kHz) HF ripple and 300 mA (120 Hz) LF ripple support demanding power stages and switching regulators.
• Wide operating temperature and long life: −55°C to +135°C range with 4,000 hours endurance at 135°C helps ensure long-term stability in harsh thermal environments.
• AEC‑Q200 qualified: Recognized qualification for designs that require automotive-grade component reliability.
• SMD-ready packaging: Compact φ10 × 10L can and embossed carrier taping streamline automated assembly and reduce board space.
• Low leakage: Specified leakage current of 67.5 µA supports effective charge retention in power-hold and standby circuits.
