Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 25 V for bulk energy storage and decoupling.
• Polymer Hybrid Construction — Conductive polymer hybrid aluminum electrolytic design for reduced ESR and improved ripple handling compared to conventional electrolytics.
• Low Impedance / ESR — ESR of 16 mΩ (measured at 20°C, 100 kHz) to support low-loss decoupling and efficient power filtering.
• High Ripple Current — Low-frequency ripple current of 525 mA (120 Hz) and high-frequency ripple current of 3.5 A (100 kHz) to handle dynamic power demands.
• Electrical Loss — Tangent of loss angle (tan δ) of 0.14 at 20°C, 120 Hz, for predictable dielectric behavior under AC conditions.
• Leakage Current — Specified leakage current of 82.5 µA, measured per standard test conditions.
• Long Life at High Temperature — Endurance rated to 4000 hours at 135°C with defined limits on capacitance change, tan δ and ESR after test.
• Wide Operating Temperature — Rated for −55°C to 135°C for use in elevated-temperature environments.
• Packaging & Mounting — Surface-mount chip can (φ10 × 10L) supplied in embossed carrier taping for automated placement; vibration resistant construction.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant as specified in the product documentation.

Typical Applications

• Automotive systems — Suitable for automotive electronics that require AEC-Q200 qualification and operation across −55°C to 135°C.
• Power supply decoupling and smoothing — Low ESR (16 mΩ) and high ripple-current capability (3.5 A @100 kHz) support stable supply rails and transient load handling.
• High-temperature electronics — Long endurance of 4000 hours at 135°C addresses thermal stress and lifetime demands in hot environments.

Unique Advantages

• Low-loss performance: 16 mΩ ESR at 100 kHz delivers efficient energy transfer and reduced heat generation under high-frequency conditions.
• High ripple tolerance: 3.5 A high-frequency ripple current rating enables reliable operation with switching regulators and power converters.
• Extended high-temperature life: 4000-hour endurance at 135°C gives predictable long-term behavior in elevated-temperature applications.
• AEC-Q200 qualification: Meets automotive-grade passive component requirements for reliability in regulated-design environments.
• SMD convenience: Embossed carrier taping and chip can package simplify automated assembly and reduce handling steps.
• Robust electrical characteristics: Defined tan δ (0.14 at 20°C/120 Hz) and controlled leakage current (82.5 µA) support predictable circuit design and margining.
