SDR1307-820KL - Bourns

SDR1307-820KL 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 ensure the voltage across the inductor does not exceed 1.5 times the rated voltage to prevent saturation and reduce the inductor's lifespan.
• 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 tolerance on inductance value, and how does it affect my design?
  The inductor's tolerance is typically ±10%. To ensure your design's performance, consider the tolerance when selecting the inductor value and designing your circuit. You may need to adjust the inductor value or add additional components to compensate for the tolerance.
