• High Ripple Current (Low Frequency) Rated ripple current of 1.735 A at 120 Hz to support substantial AC ripple in power rails.
• Temperature and Lifetime Operating range −55 °C to 105 °C with a load life specified as 2000 hours at 105 °C.
• Package & Mounting Surface-mount (radial can SMD) with body dimensions L: 8 × D: 6.3 mm and recommended land size L: 6.6 × W: 6.6 mm for compact PCB layouts.
• Soldering Compatibility Lead-free reflow compatibility with peak soldering temperature correspondence up to 260 °C.
• Polarity & Tolerance Polarized capacitor with capacitance 390 µF and tolerance ±20% at 120 Hz, 20 °C.
• Standards & Compliance AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive AEC-Q200 qualification and high ripple-current capability make this capacitor suitable for automotive electronics requiring stable power filtering and decoupling under elevated temperature and vibration conditions.

Unique Advantages

• Low ESR (14 mΩ at 100 kHz): Reduces AC losses and heat generation during high-frequency operation, improving power-stage efficiency.
• High ripple-current handling: Supports both 120 Hz and 100 kHz ripple levels (1.735 A and 3.47 A respectively), enabling reliable smoothing of noisy power rails.
• Compact SMD radial can: Small footprint (8 × 6.3 mm) and defined land pattern simplify board layout while delivering high capacitance.
• Long high-temperature life: 2000 hours at 105 °C provides predictable endurance for designs exposed to sustained elevated temperatures.
• Automotive-ready qualification: AEC-Q200 status gives design confidence for vehicle electronics and other demanding applications.
• RoHS compliant and lead-free reflow capable: Meets environmental directives and modern assembly processes with a 260 °C peak reflow correspondence.
