PWR4318W7R50JE Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal performance is to use a symmetrical layout, with the inductor centered on the PCB, and to keep the copper traces as short and wide as possible to minimize parasitic inductance and resistance.
  • To determine the correct inductor value, you need to consider the operating frequency, output voltage, and output current of your application. You can use online inductor selection tools or consult with a Bourns application engineer to determine the optimal inductor value.
  • The maximum operating temperature for the PWR4318W7R50JE is 125°C, with a derating of 1.25% per degree above 80°C.
  • Yes, the PWR4318W7R50JE is designed for high-frequency applications up to 5 MHz, making it suitable for switch-mode power supplies, DC-DC converters, and other high-frequency circuits.
  • The self-resonant frequency (SRF) of the PWR4318W7R50JE is approximately 25 MHz, which is above the typical operating frequency of most switching regulators.
