Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance for bulk energy storage and decoupling.
• High‑temperature Endurance — Specified life of 1000 hours at +150°C, enabling prolonged operation in elevated-temperature environments.
• Wide Operating Range — Operational from −55°C to +150°C to cover harsh thermal conditions.
• Vibration Resistant — Chip-type construction with vibration resistance suited to mechanically demanding installations.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.18 and a measured leakage current of 326.4 µA, supporting predictable power-supply behavior.
• Ripple Handling — Rated ripple current of 536 mA at 120 Hz and 800 mA at 10 kHz for effective smoothing across low and high frequencies.
• Package & Mounting — Surface-mount radial can (φ12.5 × 13.5 mm) supplied in embossed carrier taping for automated assembly and pick-and-place processes.
• Qualified for Automotive Use — AEC‑Q200 rating and RoHS compliance to support regulated production environments.

Typical Applications

• Automotive Electronics — Bulk smoothing and energy storage in electronic control modules and power electronics where high temperature and vibration resistance are required.
• Power Conversion & Regulation — DC‑link and output smoothing in converters and regulators that operate across wide temperature ranges.
• Industrial & Transportation Equipment — Decoupling and energy buffering in vibration-prone systems exposed to elevated ambient temperatures.

Unique Advantages

• Proven high‑temperature durability: 1000 hours at +150°C provides measurable endurance for designs that must tolerate sustained heat.
• Wide thermal operating window: −55°C to +150°C supports deployment across harsh thermal environments without added thermal management for the capacitor itself.
• Designed for mechanical stress: Vibration-resistant chip package reduces risk of mechanical failure in mobile and industrial applications.
• High capacitance in a compact SMD can: 680 µF in a φ12.5 × 13.5 mm package helps minimize board real estate while delivering required bulk capacitance.
• Automotive-grade qualification: AEC‑Q200 rating and RoHS compliance simplify qualification for regulated programs and environmentally conscious production.
• Pick-and-place ready packaging: Embossed carrier taping enables high-throughput assembly and consistent placement accuracy.
