DRQ73-220-R - Eaton

DRQ73-220-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the DRQ73-220-R?
  The recommended PCB land pattern for the DRQ73-220-R can be found in the Coiltronics application note AN-001, which provides detailed guidelines for PCB layout and design.
• How do I handle the DRQ73-220-R's high current rating in my design?
  To handle the high current rating of the DRQ73-220-R, ensure that your PCB traces and vias are designed to handle the maximum current rating. Use thick copper traces, and consider using multiple vias to reduce resistance and thermal stress.
• What is the operating temperature range for the DRQ73-220-R?
  The operating temperature range for the DRQ73-220-R is -40°C to +125°C, as specified in the datasheet. However, it's essential to consider the derating curves for inductance and current rating at higher temperatures.
• Can I use the DRQ73-220-R in a high-frequency application?
  Yes, the DRQ73-220-R is suitable for high-frequency applications up to 1 MHz. However, it's crucial to consider the inductor's self-resonant frequency (SRF) and ensure that it does not resonate at the operating frequency.
• How do I select the correct inductor value for my design?
  To select the correct inductor value, consider the required inductance, current rating, and operating frequency. Use the Coiltronics inductor selection guide or consult with an applications engineer to ensure the DRQ73-220-R meets your design requirements.
