URS2C470MHD - Nichicon

URS2C470MHD Frequently Asked Questions (FAQs)

• What is the recommended voltage derating for this capacitor?
  Nichicon recommends a voltage derating of 80% or less for the URS2C470MHD capacitor to ensure reliable operation and prevent overheating.
• How does the capacitor's ESR (Equivalent Series Resistance) change with frequency?
  The ESR of the URS2C470MHD capacitor decreases with increasing frequency. According to Nichicon's application notes, the ESR at 100 kHz is approximately 30% of the ESR at 100 Hz.
• Is the capacitor suitable for use in high-temperature environments?
  The URS2C470MHD capacitor has a maximum operating temperature of 105°C, making it suitable for use in high-temperature environments. However, the capacitor's lifespan and performance may degrade at temperatures above 85°C.
• Can the capacitor be used in DC-DC converter applications?
  Yes, the URS2C470MHD capacitor is suitable for use in DC-DC converter applications due to its low ESR and high ripple current rating. However, the capacitor's voltage rating and ripple current capability should be carefully evaluated to ensure reliable operation.
• How does the capacitor's capacitance change with temperature?
  The capacitance of the URS2C470MHD capacitor decreases with increasing temperature. According to Nichicon's datasheet, the capacitance at 105°C is approximately 80% of the capacitance at 20°C.
