2200HT-680-H-RC - Bourns

2200HT-680-H-RC 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 (AN16) and on their website. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
• How do I handle the high current rating of this inductor in my design?
  To handle the high current rating, ensure your PCB traces and vias can handle the current density. Use thick copper traces (at least 2 oz), and consider using multiple vias to reduce the current density. Also, ensure your design meets the recommended operating temperature range.
• What is the self-resonant frequency (SRF) of this inductor, and how does it affect my design?
  The SRF of the 2200HT-680-H-RC is not explicitly stated in the datasheet. However, Bourns provides an SRF calculator tool on their website. The SRF can affect your design by causing unwanted resonances and affecting the inductor's impedance. Ensure your design takes into account the SRF and its potential impact on your circuit's performance.
• Can I use this inductor in a high-temperature environment, and what are the derating factors?
  The 2200HT-680-H-RC is rated for operation up to 155°C. However, derating factors apply above 80°C. Consult the datasheet and Bourns' application notes for derating factors and guidelines on using this inductor in high-temperature environments.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize magnetic field interference, follow proper component placement and orientation guidelines. Keep the inductor away from sensitive components, and consider using shielding or mu-metal shielding to contain the magnetic field.
