EMVA160ADA470ME55G - Chemi-Con

EMVA160ADA470ME55G Frequently Asked Questions (FAQs)

• What is the recommended voltage derating for this capacitor?
  Chemi-Con recommends a voltage derating of 10-20% to ensure reliable operation and extend the lifespan of the capacitor.
• How does the capacitor's ESR (Equivalent Series Resistance) change with frequency?
  The ESR of the EMVA160ADA470ME55G capacitor decreases with increasing frequency. According to Chemi-Con's application notes, the ESR at 100 kHz is approximately 1/3 of the ESR at 100 Hz.
• What is the maximum ripple current rating for this capacitor?
  The maximum ripple current rating for the EMVA160ADA470ME55G capacitor is not explicitly stated in the datasheet. However, according to Chemi-Con's application notes, the ripple current rating can be calculated using the formula: Irms = √(ΔV^2 / (ESR * f)), where ΔV is the voltage ripple, ESR is the equivalent series resistance, and f is the frequency.
• Is the capacitor suitable for use in high-temperature environments?
  The EMVA160ADA470ME55G capacitor has a maximum operating temperature of 105°C, making it suitable for use in high-temperature environments. However, it's essential to ensure that the capacitor is properly derated and that the operating conditions do not exceed the recommended specifications.
• What is the capacitor's moisture sensitivity level (MSL)?
  The EMVA160ADA470ME55G capacitor has an MSL rating of 2, which means it can withstand exposure to moisture for up to 4 days without requiring baking or other special handling procedures.
