ULD2W680MHD Frequently Asked Questions (FAQs)

  • Nichicon recommends a layout with short leads and a large copper area for heat dissipation. A minimum of 2 oz copper thickness is recommended. The capacitor should be placed close to the power source and the high-frequency circuitry should be kept away from the capacitor.
  • The ULD2W680MHD is designed to handle high-frequency ripple current. However, the capacitor's ESR increases with frequency, which can lead to increased heat generation. Nichicon recommends derating the capacitor's ripple current capability at high frequencies (above 10 kHz).
  • Nichicon recommends a maximum voltage derating of 80% of the rated voltage to ensure reliable operation and prevent premature failure. This means that for a 680V rated capacitor, the maximum allowed voltage is 544V.
  • The ULD2W680MHD is rated for operation up to 105°C. However, Nichicon recommends derating the capacitor's voltage and ripple current capability at high temperatures (above 85°C) to ensure reliable operation.
  • The ULD2W680MHD is designed to handle power cycling and on/off switching. However, Nichicon recommends minimizing the number of power cycles and on/off switching to prevent premature failure. The capacitor's lifespan can be affected by the number of power cycles and on/off switching.
