• Conductive Polymer Electrolyte — Solid polymer chemistry provides low ESR and improved ripple handling compared to traditional electrolytics.
• Low ESR — 36 mΩ specified ESR at 100 kHz, supporting efficient high-frequency filtering and reduced dissipation.
• High Ripple Current — Handles 600 mA at 120 Hz and 1.2 A at 100 kHz, enabling reliable performance in switching regulators and power-conversion stages.
• Thermal Endurance & Operating Range — Rated for −55 °C to +125 °C with a specified lifetime of 6000 hours at 125 °C for the device size; designed for sustained operation in elevated-temperature assemblies.
• AEC‑Q200 Qualified — Qualified per AEC‑Q200 for applications requiring recognized component-level reliability (see datasheet for qualification details).
• SMD & Lead‑free Reflow Compatible — Surface-mount radial can designed for lead‑free reflow; compatible with 260 °C peak reflow profiles as specified for this series.
• Compact Footprint — Package dimensions L: 6 mm × D: 6.3 mm with recommended land size L: 6.6 × W: 6.6 mm for space-constrained board designs.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• Automotive Power Rails — Local bulk decoupling and smoothing in ECUs, power modules, and other vehicle electronics where AEC‑Q200 qualification and high-temperature operation are required.
• DC‑DC Converter Output Filtering — Low ESR and high ripple current handling reduce voltage ripple and thermal stress on regulator outputs.
• High‑Temperature Electronics — Use in control modules and power assemblies that operate across a −55 °C to +125 °C range and require reflow-compatible SMD components.
• Compact Power Modules — Small can package and SMD mounting enable placement in space‑constrained boards for onboard power stabilization.

Unique Advantages

• Low ESR for High-Frequency Performance: 36 mΩ at 100 kHz minimizes series losses and improves filtering effectiveness at switching frequencies.
• High Ripple Current Capability: Rated at 1.2 A (100 kHz) and 600 mA (120 Hz), enabling reliable operation in high-current power stages and reducing thermal buildup.
• Extended High-Temperature Life: Specified lifetime of 6000 hours at 125 °C supports long-term reliability in elevated-temperature applications.
• AEC‑Q200 Qualification: Qualification for automotive-grade reliability simplifies part selection for vehicle electronics and other high-reliability systems.
• Reflow-Ready SMD Form Factor: Lead‑free reflow compatibility to 260 °C peak allows standard SMT assembly and two reflow passes as specified.
• Small Board Footprint: Compact 6 × 6.3 mm can and recommended 6.6 × 6.6 mm land pattern save PCB area while providing adequate capacitance and performance.
