• Surface-mount, tape-fed packaging — Chip-type radial can SMD package suitable for automatic mounting machines; recommended land size L: 1.28 × W: 1.28 cm.
• Polarized with low leakage — Polarized device with leakage current specified as not more than 0.01CV (µA) after 2 minutes at 20°C (per datasheet).
• AEC-Q200 qualified & RoHS compliant — Meets AEC-Q200 qualification and complies with RoHS (2011/65/EU, (EU)2015/863).
• Compact footprint — Package dimensions L: 1.35 × D: 1.25 cm with seated height and land pattern optimized for board-level density.

Typical Applications

• Automotive electronic systems — Bulk decoupling and smoothing on power rails in modules that require AEC-Q200-level qualification and sustained operation to +125°C.
• Power supply filtering — Bulk energy storage and ripple suppression in DC–DC converters and regulator outputs operating at elevated temperatures.
• Power conversion modules — Filtering and energy buffering in inverters, motor drives, and other high-temperature power electronics where low ESR and high ripple current are important.
• High-temperature electronics — Board-level decoupling and bulk capacitance for systems that must survive extended exposure to +125°C environments.

Unique Advantages

• High-temperature endurance: 3000 hours rated at 125°C provides predictable long-term performance in hot environments.
• Low-temperature ESR characterization: ESR specified at 100 kHz and validated after -40°C testing, supporting reliable operation across the full temperature range.
• Strong ripple handling: Rated ripple currents of 850 mA (120 Hz) and 1.7 A (10 kHz) support demanding power filtering duties.
• Automated assembly ready: Chip-type SMD radial can packaged for carrier-tape feeding simplifies high-volume PCB assembly.
• Automotive-grade qualification: AEC-Q200 qualification and RoHS compliance make the part suitable for regulated automotive and industrial programs.
• Compact board impact: Small footprint and defined land pattern (1.28 × 1.28 cm) help conserve PCB area while delivering high capacitance.
