TNR14V471K - Chemi-Con

TNR14V471K 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 TNR14V471K 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.
• Is the capacitor suitable for use in high-temperature environments?
  The TNR14V471K capacitor is rated for operation up to 125°C, but Chemi-Con recommends derating the voltage and current ratings for extended operation above 105°C to ensure reliability.
• What is the recommended mounting and soldering method for this capacitor?
  Chemi-Con recommends using a reflow soldering process with a peak temperature of 260°C for 10-30 seconds. For hand soldering, use a soldering iron with a temperature of 350°C or less.
• Are there any specific considerations for using this capacitor in high-vibration or high-shock environments?
  Yes, Chemi-Con recommends using a capacitor with a longer lead length (e.g., 10 mm or more) to reduce the risk of mechanical stress and vibration-induced failure.
