400HXW270MEFR18X50 - Rubycon

400HXW270MEFR18X50 Frequently Asked Questions (FAQs)

• What is the recommended voltage derating for high-reliability applications?
  Rubycon recommends a derating of 10-15% for high-reliability applications to ensure long-term reliability and minimize the risk of capacitor failure.
• How does the capacitor's ESR affect its performance in high-frequency circuits?
  The ESR (Equivalent Series Resistance) affects the capacitor's performance in high-frequency circuits. A lower ESR results in less energy loss and improved overall circuit performance. The 400HXW270MEFR18X50 has a relatively low ESR of 18mΩ, making it suitable for high-frequency applications.
• What is the recommended storage condition for these capacitors to prevent degradation?
  Rubycon recommends storing the capacitors in a dry, cool place with a temperature range of -20°C to 40°C and relative humidity below 80%. Avoid storing the capacitors in direct sunlight, as this can cause degradation over time.
• Are these capacitors suitable for use in high-temperature environments?
  The 400HXW270MEFR18X50 has a maximum operating temperature of 105°C. While it can operate in high-temperature environments, it's essential to consider the derating factors and ensure the capacitor from excessive heat to prevent premature failure.
• What is the recommended soldering profile for these capacitors?
  Rubycon recommends a soldering profile with a peak temperature of 260°C, a soldering time of 3-5 seconds, and a preheating temperature of 150°C to 180°C. This ensures a reliable solder joint and minimizes the risk of damage to the capacitor.
