• ESR Performance — Equivalent series resistance of 150 mΩ measured at 100 kHz, with ESR specification verified following the −40 °C test.
• Ripple Current Handling — 250 mA at 120 Hz and 500 mA at 10 kHz, enabling filtering for both low‑ and high‑frequency ripple components.
• Surface‑Mount Can Package — Chip‑type radial can in SMD format compatible with automatic mounting machines fed with carrier tape; compact 1 cm × 1 cm footprint and matching land pattern guidance.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, supporting use in regulated environments and long‑lifecycle products.
• Reliability Characteristics — Endurance criteria: capacitance change within ±30% after 2000 hours at 135 °C; stable leakage and tan δ limits per datasheet endurance test.

Typical Applications

• Automotive power modules — Bulk decoupling and smoothing in electronic control units and power distribution modules where AEC‑Q200 qualification and high‑temperature capability are required.
• DC‑DC converters — Output filtering for low‑voltage converters that demand low ESR at high frequency and stable performance from −40 °C to +135 °C.
• Harsh‑environment industrial electronics — Power filtering in industrial sensors and control systems exposed to wide temperature ranges and thermal stress.
• Telematics and infotainment power rails — Energy storage and ripple suppression for onboard electronics that require reliable SMD mounting and long‑term endurance.

Unique Advantages

• High‑temperature endurance: Rated to +135 °C with 2000 hours endurance, supporting designs exposed to elevated operating temperatures.
• Automotive‑grade qualification: AEC‑Q200 qualification enables use in automotive systems and other regulated applications requiring component-level qualification.
• Verified low‑temperature ESR behavior: ESR specification includes results after a −40 °C test, providing clearer performance expectations across the full operating range.
• SMD compatibility for automated assembly: Designed for carrier‑tape feed and surface mounting to simplify high‑volume PCB assembly and reduce handling steps.
• Balanced ripple handling: Specified ripple currents at both 120 Hz and 10 kHz make the part suitable for mixed-frequency power environments.
