SDR6603-101M - Bourns

SDR6603-101M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize electromagnetic interference (EMI), keep the inductor at least 5 mm away from sensitive components. You can also use shielding techniques, such as copper tape or mu-metal shielding, to contain the magnetic field.
• What is the maximum allowable voltage across the inductor?
  While the datasheet specifies a maximum rated current, it's essential to consider the voltage across the inductor as well. As a general rule, keep the voltage across the inductor below 1.5 times the rated voltage to prevent saturation and ensure reliable operation.
• How do I handle the inductor's self-resonant frequency (SRF) in my design?
  The SRF is typically above the operating frequency range. However, if your design operates near the SRF, consider adding a damping resistor in series with the inductor to minimize resonance effects.
• What is the inductor's thermal derating curve, and how does it affect my design?
  Bourns provides a thermal derating curve in their datasheet. This curve shows the inductor's current-carrying capacity at elevated temperatures. Ensure your design takes into account the reduced current rating at higher temperatures to prevent overheating and ensure reliability.
