• Low impedance performance: Specified impedance of 170 mΩ provides low ESR behavior for improved power stability in compact circuits.
• Ripple current capability: Rated ripple current of 450 mA at 120 Hz and 675 mA at 10 kHz supports AC ripple smoothing across a range of frequencies.
• Temperature and endurance: Operating temperature range from -55 °C to +105 °C with a rated lifetime of 5000 hours at 105 °C.
• Package and mounting: Chip‑type, can SMD package sized L: 1 × D: 0.8 cm with recommended surface mount land size 8.3 × 8.3 mm; designed for surface mounting on high‑density PC boards and compatible with carrier‑tape automated mounting.
• Automotive qualification and environmental compliance: AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronic modules: Use in automotive control and power modules that require components qualified to AEC‑Q200 and rated for extended operation at elevated temperatures.
• High‑density PCB power circuits: Surface‑mount format and compact size allow placement on densely populated boards where space and reliable power decoupling are critical.
• Power smoothing and ripple suppression: Low impedance and specified ripple current ratings support AC ripple smoothing in compact DC power systems.
• Automated assembly lines: Designed for carrier‑tape feeding and placement by automatic mounting machines to streamline high‑volume PCB assembly.

Unique Advantages

• Long high‑temperature endurance: 5000 hours at 105 °C delivers predictable lifetime performance in elevated‑temperature environments.
• AEC‑Q200 qualification: Provides an automotive‑grade reliability benchmark for designs targeting transportation and other rugged markets.
• Low impedance and frequency range ripple handling: 170 mΩ impedance and specified ripple currents at 120 Hz and 10 kHz help maintain stable power rails across common switching frequencies.
• Compact SMD can package: Small footprint (L: 1 × D: 0.8 cm) and defined land pattern (8.3 × 8.3 mm) enable placement on space‑constrained, high‑density PCBs.
• Assembly‑friendly design: Chip type compatible with carrier‑tape automated mounting reduces manual handling and supports efficient production flow.
• Regulatory compliance: RoHS conformity reduces material‑restriction risks for global product deployments.
