450MXK270MEFCSN25X35 - Rubycon

450MXK270MEFCSN25X35 Frequently Asked Questions (FAQs)

• What is the recommended voltage derating for this capacitor?
  Rubycon 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 450MXK270MEFCSN25X35 capacitor decreases with increasing frequency. According to Rubycon's application notes, the ESR at 100 kHz is approximately 1/3 of the ESR at 100 Hz.
• Is the capacitor suitable for high-temperature applications?
  The 450MXK270MEFCSN25X35 capacitor has a maximum operating temperature of 125°C, making it suitable for high-temperature applications. However, the capacitor's lifespan and performance may degrade at elevated temperatures.
• What is the recommended mounting and soldering method for this capacitor?
  Rubycon recommends using a reflow soldering method with a peak temperature of 260°C for 10-30 seconds. The capacitor should be mounted with the terminals facing downwards to prevent moisture ingress.
• Are there any specific storage and handling precautions for this capacitor?
  Yes, Rubycon recommends storing the capacitors in a dry, cool place, away from direct sunlight and moisture. The capacitors should be handled with care to prevent mechanical stress and electrostatic discharge.
