EMVA500ADA220MF55G - Chemi-Con

EMVA500ADA220MF55G Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for this capacitor?
  The recommended PCB layout and land pattern can be found in Chemi-Con's application note AN-1001, which provides guidelines for optimal mounting and layout of their aluminum electrolytic capacitors.
• How does the capacitor's ESR (Equivalent Series Resistance) change with frequency?
  While the datasheet provides the ESR value at 100 kHz, Chemi-Con can provide additional ESR vs. frequency data upon request. Alternatively, engineers can use industry-standard ESR modeling tools to estimate the ESR at different frequencies.
• What is the capacitor's ripple current rating at high frequencies (e.g., 10 kHz to 100 kHz)?
  The datasheet provides the ripple current rating at 120 Hz, but for high-frequency applications, engineers should consult Chemi-Con's application note AN-1002, which provides guidelines for calculating the ripple current rating at higher frequencies.
• How does the capacitor's performance change with temperature?
  While the datasheet provides the capacitor's specifications at 20°C, Chemi-Con can provide additional data on the capacitor's performance at different temperatures upon request. Engineers can also use industry-standard models to estimate the capacitor's performance at different temperatures.
• Is the capacitor suitable for use in high-reliability or safety-critical applications?
  The EMVA500ADA220MF55G is a standard-grade capacitor, but Chemi-Con offers high-reliability and safety-critical versions of their capacitors with additional screening and testing. Engineers should consult Chemi-Con's product catalog or contact their sales representative for more information.
