• Surface-Mount Radial Can Package — Package case listed as radial, can - SMD enables placement on high-density PCBs and compatibility with automatic pick-and-place via carrier tape.
• Automated Assembly Ready — Designed for surface mounting on boards and applicable to automatic mounting machines fed with carrier tape.
• Wide Operating Temperature — Rated from −55 °C to +105 °C to cover harsh thermal environments.
• Long High‑Temperature Lifetime — 5000 hours at 105 °C endurance rating for long-term operation under elevated temperatures.
• Ripple Current Capability — Rated ripple currents of 810 mA at 120 Hz and 931.5 mA at 10 kHz to support dynamic load conditions.
• Polarized Design with Standard Tolerance — Polarized capacitor with tolerance of −20% to +20% for design predictability.
• AEC‑Q200 Qualified & RoHS Compliant — AEC‑Q200 qualification and RoHS compliance align this part with automotive and regulated-environment requirements.
• Compact Dimensions and PCB Land Pattern — Physical size L: 2.1 × D: 1.25 cm with recommended surface-mount land size L: 1.28 × W: 1.28 cm for layout planning.

Typical Applications

• Automotive Electronic Modules — Suited for automotive control units and power modules that require AEC‑Q200 qualified bulk capacitance in an SMD form factor.
• High‑Density PCB Power Rails — Provides bulk decoupling and energy storage on compact, high-density circuit boards where board area is constrained.
• Automated Production Lines — Designed for carrier-tape feeding and automatic mounting, easing integration into high-volume SMT assembly processes.

Unique Advantages

• Compact bulk capacitance: 2.2 mF in a small radial can SMD package reduces system board area for energy storage needs.
• Automotive-grade reliability: AEC‑Q200 qualification provides a verified quality baseline for automotive and similarly stringent applications.
