B82479A1104M000 - TDK

B82479A1104M000 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the B82479A1104M000 can be found in the TDK Corporation's application note or footprint library. It typically includes a rectangular pad with a size of around 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's terminal.
• How do I handle the inductor's thermal derating?
  The thermal derating of the B82479A1104M000 inductor is typically handled by reducing the maximum current rating as the operating temperature increases. TDK Corporation provides a thermal derating curve in the datasheet, which shows the maximum current rating at different temperatures. Engineers can use this curve to determine the maximum current rating for their specific application.
• What is the inductor's self-resonant frequency?
  The self-resonant frequency of the B82479A1104M000 inductor is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance value and the parasitic capacitance. Typically, the self-resonant frequency of this inductor is in the range of 100-200 MHz.
• Can I use this inductor in a high-frequency application?
  The B82479A1104M000 inductor is designed for general-purpose use and may not be suitable for high-frequency applications above 10 MHz. For high-frequency applications, TDK Corporation offers other inductor series with lower parasitic capacitance and higher self-resonant frequencies.
• How do I ensure the inductor's reliability in a high-reliability application?
  To ensure the reliability of the B82479A1104M000 inductor in a high-reliability application, engineers should follow proper storage and handling procedures, use a robust PCB design, and implement adequate thermal management. Additionally, TDK Corporation provides reliability data and guidelines for using their inductors in high-reliability applications.
