Frequently Asked Questions
What is the maximum ripple current?
The rated ripple current is 8.5A at 85C and 120Hz. This high ripple current rating makes it suitable for high-power power supply applications. At lower temperatures, the capacitor can handle proportionally higher ripple currents.
For applications exceeding 8.5A ripple current, consider using multiple capacitors in parallel.
What is the expected lifetime?
The rated lifetime is 5,000 hours at 85C. Using the Arrhenius equation, expected lifetime extends to approximately 20,000 hours at 65C. Every 10C reduction in operating temperature approximately doubles the capacitor lifetime.
For maximum lifetime, operate at lowest practical temperature with 80% voltage derating.
What mounting considerations apply?
Snap-in capacitors require proper PCB mounting holes sized for the snap-in terminals. Standard hole spacing is 7.5mm for this case size. The PCB must provide adequate copper area for heat dissipation.
Design PCB with proper hole sizes and spacing. Provide adequate copper area for thermal management.
What voltage derating is recommended?
Industry best practice recommends operating at no more than 80% of rated voltage. For this 63V capacitor, maximum operating voltage should be 50V. For detailed specifications and application support on aishi SN-22000uF-63V, refer to the datasheet or contact our team.
Design for 80% voltage derating for optimal reliability.
Can multiple capacitors be paralleled?
Yes, multiple snap-in capacitors can be connected in parallel to increase total capacitance and share ripple current. When paralleling, total capacitance adds linearly while ESR reduces proportionally.
For very high current applications, parallel multiple capacitors. Ensure symmetrical layout for balanced current sharing.
