SDR1030-150M - Bourns

SDR1030-150M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the SDR1030-150M?
  Bourns provides a recommended PCB layout and land pattern in their application note AN204, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal management and to minimize electromagnetic interference (EMI).
• How do I select the correct current rating for my application?
  To select the correct current rating, you need to consider the maximum current required by your circuit, as well as the ambient temperature and the desired temperature rise. Bourns provides a current rating vs. temperature rise graph in the datasheet, which can help you make this determination.
• What is the maximum voltage rating for the SDR1030-150M?
  The maximum voltage rating for the SDR1030-150M is 150V, as indicated in the part number. However, it's essential to note that the voltage rating may be derated depending on the operating temperature and other environmental factors.
• Can I use the SDR1030-150M in a high-frequency application?
  While the SDR1030-150M is primarily designed for DC-DC converters and other low-frequency applications, it can be used in high-frequency applications up to 1 MHz. However, you'll need to consider the inductor's self-resonant frequency, core losses, and other high-frequency effects when designing your circuit.
• How do I ensure the inductor is properly secured to the PCB to prevent vibration and mechanical stress?
  Bourns recommends using a suitable adhesive, such as a thermally conductive epoxy, to secure the inductor to the PCB. Additionally, you can use a mechanical clamp or a bracket to further secure the inductor and prevent vibration and mechanical stress.
