• Long-Life Endurance — Load life specified at 5000 hours at 105°C, with defined post-test limits for capacitance, tan δ and ESR.
• Low ESR & High-Frequency Performance — ESR of 28 mΩ measured at 100 kHz (20°C), supporting high-frequency ripple handling.
• Ripple Current Capability — Rated ripple current of 1.4 A at 120 Hz and 2.8 A at 100 kHz, enabling robust handling of AC stress in power circuits.
• Temperature Range — Operating range from −55°C to +105°C, with impedance stability specified at −55°C and +105°C relative to +20°C.
• Surface-Mount, Reflow-Compatible Package — Chip-type SMD can be processed with lead-free reflow (peak correspondence at 260°C) and has recommended land size of 8.3 × 8.3 mm; case footprint is approximately L:7 × D:8 mm.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized Device — Polarized capacitor for DC applications.

Typical Applications

• Automotive Electronics — Designed for automotive use where AEC-Q200 qualification and long high-temperature life (5000 h at 105°C) are required.
• Power Supply Filtering — Low ESR and specified ripple current at 100 kHz support filtering and decoupling in compact power modules.
• High-Temperature Environments — Suitable for assemblies that must operate across −55°C to +105°C with controlled impedance variation at temperature extremes.

Unique Advantages

• Long steady-state life: 5000 hours at 105°C provides predictable end-of-life behavior for designs requiring extended thermal endurance.
• Automotive-grade qualification: AEC-Q200 status supports use in systems with automotive reliability requirements.
• High ripple handling with low ESR: 28 mΩ ESR at 100 kHz combined with 2.8 A ripple current rating at 100 kHz helps maintain stable voltage under dynamic loads.
• Reflow-compatible SMD package: Supports lead-free reflow processing (260°C peak correspondence) for modern assembly flows.
• Wide operating temperature: −55°C to +105°C range and specified impedance ratios at −55°C and +105°C ensure consistent performance across temperature extremes.
• RoHS compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for environmentally conscious designs.
