• Electrical Ratings  12 µF capacitance at a rated voltage of 63 V with capacitance tolerance of ±20% (120 Hz, 20°C).
• Low ESR & High Ripple Handling  ESR of 51 mΩ measured at 100 kHz and rated ripple currents of 350 mA at 120 Hz and 700 mA at 100 kHz support high‑frequency decoupling and power-stage smoothing.
• High‑Temperature Endurance  Long life specification of 4000 hours at 135°C; endurance characteristics include defined limits for capacitance change, tan δ and ESR after test.
• Automotive Qualification  AEC‑Q200 qualified, meeting automotive-grade reliability requirements.
• Reflow & Environmental Compliance  Lead‑free reflow soldering compatible with a 260°C peak profile and RoHS compliant (2011/65/EU, (EU)2015/863).
• Operating Temperature & Robustness  Rated operating temperature range of -55°C to +135°C with specified impedance behavior across temperature extremes.
• Package & PCB Land  Compact SMD can: 6 × 6.3 mm (L × D) with recommended land size 6.6 × 6.6 mm, suitable for dense board layouts.

Typical Applications

• Automotive electronics  AEC‑Q200 qualification and extended high‑temperature endurance make this capacitor suitable for control modules and power electronics in automotive systems.
• High‑temperature control and power modules  Rated for operation up to 135°C and specified for 4000 hours at that temperature, supporting designs that must sustain elevated ambient temperatures.
• SMD power stages and high‑frequency decoupling  Low ESR (51 mΩ at 100 kHz) and defined ripple current ratings at 100 kHz enable reliable decoupling in compact surface‑mount power circuits.

Unique Advantages

• Long high‑temperature lifetime: 4000 hours at 135°C provides predictable aging and retention characteristics for designs exposed to sustained heat.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in applications with demanding qualification and reliability requirements.
• Low ESR with high ripple capability: 51 mΩ at 100 kHz and up to 700 mA ripple current at 100 kHz improve transient handling and reduce losses in power circuits.
• Surface‑mount convenience: Compact 6 × 6.3 mm SMD can and a 6.6 × 6.6 mm recommended land reduce board area and simplify automated assembly.
• Lead‑free reflow compatible: Designed for lead‑free reflow up to a 260°C peak, enabling modern SMD assembly flows while maintaining performance.
