UP2B-2R2-R - Eaton

UP2B-2R2-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the UP2B-2R2-R?
  The recommended PCB land pattern for the UP2B-2R2-R is a rectangular pad with a size of 2.5mm x 1.5mm, with a 0.5mm clearance around the pad to ensure proper soldering and to prevent electrical shorts.
• Can I use the UP2B-2R2-R in a high-temperature environment?
  The UP2B-2R2-R is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation. It's also important to consider the PCB material and other components' temperature ratings when designing for high-temperature applications.
• How do I handle the UP2B-2R2-R's magnetic field in a densely populated PCB?
  To minimize the impact of the UP2B-2R2-R's magnetic field on nearby components, it's recommended to keep a minimum distance of 5mm between the inductor and other components, and to orient the inductor to minimize the magnetic field's effect on adjacent components. Additionally, consider using shielding or magnetic shielding materials to contain the magnetic field.
• What is the self-resonant frequency of the UP2B-2R2-R?
  The self-resonant frequency of the UP2B-2R2-R is typically around 100-150 MHz, but this can vary depending on the specific application and PCB layout. It's essential to consider the self-resonant frequency when designing filters or other high-frequency circuits to ensure optimal performance.
• Can I use the UP2B-2R2-R in a switching regulator application?
  Yes, the UP2B-2R2-R is suitable for switching regulator applications due to its low DC resistance and high current rating. However, it's essential to consider the inductor's core loss and saturation characteristics to ensure reliable operation and to prevent overheating.
