• Life and endurance — Rated for 5000 hours at 105°C (load life), supporting long-term operation in elevated temperature environments.
• Loss characteristic (tan δ) — Specified tan δ of 0.28 (measurement condition: 20°C, 120 Hz) to quantify dielectric loss behavior.
• Ripple current capability — Handles 320 mA at 120 Hz and 480 mA at 10 kHz, suitable for power filtering and decoupling under AC ripple conditions.
• Leakage current — Measured leakage current of 29.61 µA under the specified test conditions.
• Temperature range — Robust operating range from -55°C to +105°C for broad environmental tolerance.
• Package and mounting — Surface-mount chip-type can (Radial, Can - SMD), size φ10×10L with surface mount land size L:1.03 × W:1.03 cm; supplied in embossed carrier taping for automated assembly.
• Compliance and qualification — AEC-Q200 qualified and RoHS compliant as indicated for the series.

Typical Applications

• Automotive electronics — Power rail filtering and energy smoothing in automotive modules, leveraging AEC-Q200 qualification and 105°C load-life endurance.
• High-density PCB power subsystems — SMD chip form factor and embossed carrier taping support automated placement in compact power supply designs.
• DC–DC converters and regulators — Ripple current ratings at both low and high frequency make this capacitor suitable for bulk filtering and decoupling on converter outputs.

Unique Advantages

• Long elevated-temperature life — 5000 hours at 105°C provides design confidence for applications with sustained high ambient temperatures.
• AEC-Q200 qualification — Series-level qualification supports use in automotive and other demanding reliability environments.
• Dual-frequency ripple handling — Specified ripple currents of 320 mA (120 Hz) and 480 mA (10 kHz) address both low- and high-frequency power disturbances.
• Clear electrical characterization — Specified tan δ (0.28 at 20°C, 120 Hz) and measured leakage current (29.61 µA) enable predictable design margining.
• SMD chip format with taped packaging — φ10×10L can size and embossed carrier taping streamline automated assembly on high-density boards.
• Wide operating temperature — -55°C to +105°C range supports deployment across diverse environmental conditions.
