UVR2A471MHD - Nichicon

UVR2A471MHD Frequently Asked Questions (FAQs)

• What is the recommended voltage derating for this capacitor?
  Nichicon recommends derating the voltage by 10-20% to ensure reliable operation and prevent overheating.
• How does the capacitor's ESR (Equivalent Series Resistance) change with frequency?
  The ESR of the UVR2A471MHD capacitor decreases with increasing frequency, but the datasheet does not provide a specific graph. However, Nichicon's application notes suggest that the ESR at 100 kHz is typically around 10-20% of the ESR at 100 Hz.
• What is the maximum ripple current rating for this capacitor?
  The maximum ripple current rating for the UVR2A471MHD capacitor is not explicitly stated in the datasheet. However, Nichicon's application notes suggest that the capacitor can handle a maximum ripple current of around 2-3 Arms at 100 kHz, depending on the operating temperature and voltage.
• How does the capacitor's capacitance change with temperature?
  The capacitance of the UVR2A471MHD capacitor decreases with increasing temperature, with a typical temperature coefficient of -55 ppm/°C. This means that the capacitance will decrease by approximately 0.055% for every 1°C increase in temperature.
• Is the capacitor suitable for use in high-reliability applications?
  Yes, the UVR2A471MHD capacitor is suitable for use in high-reliability applications, such as aerospace, automotive, and medical devices. Nichicon's manufacturing process and quality control measures ensure that the capacitor meets the requirements for high-reliability applications.
