EEUFS1K681 Frequently Asked Questions (FAQs)

  • Panasonic recommends a PCB layout with a large copper area for the capacitor pads, and a short and wide connection to the power plane to minimize ESR. A 4-layer PCB with a dedicated power plane is also recommended.
  • The EEUFS1K681 is designed to handle high-frequency ripple current, but it's essential to consider the frequency and amplitude of the ripple current when selecting the capacitor. Panasonic provides a ripple current vs. frequency chart in the datasheet to help with selection.
  • Panasonic provides a derating curve in the datasheet, which shows the reduction in capacitance and increase in ESR as the temperature increases. Engineers should derate the capacitor's capacitance and consider the increased ESR when operating at high temperatures.
  • Yes, the EEUFS1K681 is designed to withstand high vibrations. Panasonic specifies a vibration endurance of 10-2000Hz, 1.5mm amplitude, and 3 hours per axis. However, it's essential to ensure the capacitor is properly mounted and secured to the PCB to prevent mechanical stress.
  • The EEUFS1K681 is designed to handle power cycling and on/off switching, but it's essential to consider the number of cycles and the rate of change of voltage and current. Panasonic recommends following the recommended voltage and current ratings to ensure the capacitor's reliability.
