Key Features

• Capacitance & Voltage: 680 µF nominal capacitance at a rated voltage of 25 V, with a tolerance of -20% to +20% for predictable bulk energy storage.
• High-temperature Endurance: Load life of 5000 hours at 125°C; endurance specifications include capacitance change within ±30% after the rated test.
• Automotive Qualification: AEC-Q200 Qualified and explicitly described as suited for automobile electronics, supporting use where heavy-duty service is required.
• Wide Operating Range: Rated for −55°C to +125°C to cover harsh thermal environments common in automotive and industrial applications.
• Ripple Current Capability: Handles 804 mA at 120 Hz and 1.2 A at 10 kHz, enabling effective smoothing under both low- and high-frequency ripple conditions.
• Leakage and Loss Characteristics: Leakage current specification of ≤ 0.03CV (µA) after 1 minute at 20°C; maximum tan δ for the 25 V rating is 0.16, supporting stable ESR behavior.
• Compact Surface-Mount Package: Chip-type radial can in an SMD package with physical dimensions L: 2.15 × D: 1.6 cm and recommended land size L: 1.63 × W: 1.63 cm for PCB integration.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated manufacturing requirements.

Typical Applications

• Automotive electronics: Energy storage and smoothing in electronic modules where long life at elevated temperatures and vibration resistance are required.
• Power supply decoupling in harsh environments: Bulk capacitance for voltage stabilization in systems operating across −55°C to +125°C.
• High-temperature electronics: Designed for assemblies that must maintain capacitance and leakage performance after prolonged exposure to 125°C.

Unique Advantages

• Long high-temperature life: 5000-hour rated life at 125°C reduces replacement frequency and supports extended field operation in hot environments.
• Automotive-grade reliability: AEC-Q200 qualification and explicit suitability for automobile electronics provide confidence for vehicle-level designs.
• High ripple tolerance: Rated ripple currents at both 120 Hz and 10 kHz help ensure effective smoothing across a range of switching and supply conditions.
• Compact SMD can format: Chip-type surface-mount construction offers board-space-efficient bulk capacitance for dense power electronics layouts.
• Measured leakage and loss performance: Defined leakage current limit (≤ 0.03CV µA) and specified tan δ support predictable thermal and electrical behavior in system models.
• Regulatory readiness: RoHS compliance simplifies integration into designs targeted for regulated markets.
