UP4B-470-R - Eaton

UP4B-470-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  The recommended PCB layout and land pattern can be found in the Coiltronics application note AN-13, which provides guidelines for optimal performance and reduced electromagnetic interference (EMI).
• How does the inductor perform in high-temperature environments?
  The UP4B-470-R is rated for operation up to 125°C, but derating may be necessary for temperatures above 105°C. Consult the Coiltronics temperature derating chart for specific guidance.
• What is the self-resonant frequency (SRF) of the inductor?
  The SRF of the UP4B-470-R is typically around 150 MHz, but this can vary depending on the specific application and PCB layout. It's recommended to consult the Coiltronics application note AN-12 for more information on SRF and how to minimize its impact.
• Can the inductor be used in a high-current switching application?
  Yes, the UP4B-470-R is designed for high-current switching applications, but it's essential to ensure that the inductor is properly sized and that the PCB layout is optimized to handle the high currents and associated thermal stresses.
• What is the recommended storage and handling procedure to prevent damage?
  Coiltronics recommends storing the UP4B-470-R in a dry, cool place, away from direct sunlight and moisture. Handling should be done with care to avoid mechanical stress, and ESD precautions should be taken to prevent damage from static electricity.
