UMA1E4R7MDD Frequently Asked Questions (FAQs)

  • Nichicon recommends a voltage derating of 80% or less to ensure reliable operation and extend the lifespan of the capacitor.
  • The ESR of the UMA1E4R7MDD is relatively low, which means it can handle high-frequency switching and reduce energy losses. However, it's essential to consider the ESR when designing the circuit to ensure optimal performance.
  • While the capacitor is rated for operation up to 105°C, it's essential to consider the derating curve and ensure the capacitor doesn't exceed its maximum operating temperature to maintain reliability.
  • The capacitance of the UMA1E4R7MDD decreases as the temperature increases. According to the datasheet, the capacitance can decrease by up to 20% at 105°C compared to its nominal value at 20°C.
  • Nichicon provides a recommended land pattern and soldering process in their documentation. It's essential to follow these guidelines to ensure reliable solder joints and prevent damage to the capacitor.
