SRU1048-4R7Y Frequently Asked Questions (FAQs)

  • The recommended land pattern for the SRU1048-4R7Y can be found in the Bourns Application Note S-8151, which provides guidelines for PCB layout and land pattern design.
  • To handle the high current rating of the SRU1048-4R7Y, ensure that the PCB traces and vias are designed to handle the maximum current rating of the inductor. Use a sufficient trace width and via size to minimize resistance and heat generation.
  • The derating curve for the SRU1048-4R7Y can be found in the datasheet, which provides information on the inductor's current rating vs. ambient temperature. The curve helps designers determine the maximum current rating at a given temperature.
  • To select the correct SRU1048-4R7Y inductor, consider factors such as the required inductance value, current rating, and operating frequency. Use Bourns' online inductor selection tool or consult with a Bourns application engineer for assistance.
  • The SRU1048-4R7Y has a tolerance of ±20% on its inductance value. This means that the actual inductance value may vary by up to 20% from the nominal value specified in the datasheet.
