DRQ73-150-R - Eaton

DRQ73-150-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Coiltronics recommends a PCB layout with a solid ground plane underneath the inductor, and keeping the traces as short and wide as possible to minimize parasitic inductance and resistance.
• How does the inductor perform in high-temperature environments?
  The DRQ73-150-R is rated for operation up to 125°C, but derating is recommended above 85°C to ensure reliability and prevent thermal runaway. Consult the datasheet for specific derating curves.
• What is the self-resonant frequency (SRF) of the inductor?
  The SRF of the DRQ73-150-R is typically around 150-200 MHz, but this can vary depending on the specific application and PCB layout. It's essential to consider SRF when designing high-frequency circuits.
• Can I use this inductor in a switching regulator design?
  Yes, the DRQ73-150-R is suitable for switching regulator designs, but ensure that the inductor is properly sized for the specific application, and consider factors like core loss, saturation, and EMI.
• What is the recommended storage and handling procedure for these inductors?
  Coiltronics recommends storing the inductors in a dry, cool place, away from direct sunlight and moisture. Handle the components by the body, avoiding touching the leads or core to prevent damage or contamination.
