This part targets applications that require reliable bulk capacitance and stable performance across a wide temperature range, with endurance and low-temperature ESR characteristics specifically documented for high-reliability designs.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 10 V with ±20% tolerance, providing bulk energy storage suitable for decoupling and smoothing functions in power systems.
• High Temperature Operation — Specified for continuous use from -40 °C to +125 °C, with endurance tested to 2000 hours at 125 °C.
• Low-Temperature ESR Specification — ESR performance is specified after testing at -40 °C (added low-temperature ESR specification), supporting predictable behavior in cold-start conditions.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant, indicating suitability for reliability-conscious applications including automotive electronics.
• Surface-Mount Packaging — Chip-type aluminum electrolytic in an SMD can package compatible with carrier-tape automatic placement; recommended land pattern 8.3 × 8.3 mm for PCB design.
• Endurance and Stability — Meets endurance criteria after 2000 hours at 125 °C with capacitance change within ±30%, leakage current within initial limits, and tan δ limited to specified multiple of initial value.
• Leakage Current — After 1 minute at rated voltage and 20 °C, leakage current is specified as ≤ 0.03CV or 4 µA, whichever is greater.
• Ripple Current Ratings — Ripple current specified at 125 mA (120 Hz) and 250 mA (10 kHz), allowing designers to size parts for expected AC stress.

Typical Applications

• Automotive Electronics — Suited for automotive control modules and subsystems where AEC-Q200 qualification and wide temperature range are required.
• High-Temperature Electronic Assemblies — Ideal for equipment and PCBs that operate continuously at elevated temperatures up to 125 °C.
• Automated Surface-Mount Production — Designed for carrier-tape feeding and automatic placement, streamlining high-volume SMT assembly processes.

Unique Advantages

• Documented High-Temperature Endurance — 2000 hours at 125 °C verification provides quantifiable lifetime data for reliability planning.
• Cold-Start Performance Specified — ESR specified after -40 °C testing helps ensure predictable low-temperature behavior in system-level validation.
• AEC-Q200 Qualification — Qualification supports use in reliability-driven segments such as automotive electronics where component-level robustness is required.
• Assembly-Ready SMD Format — Carrier-tape compatible chip package and a defined PCB land pattern (8.3 × 8.3 mm) reduce assembly risk and speed production setup.
• Regulatory Compliance — RoHS compliant for environmental and regulatory alignment in global production.
• Measured Leakage and Ripple Specs — Clear leakage current and ripple current specifications enable accurate thermal and reliability calculations during design.
