DRQ74-100-R - Eaton

DRQ74-100-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 DRQ74-100-R is rated for operation up to 125°C, but derating may be necessary for temperatures above 100°C. Consult Coiltronics' application notes for specific guidance on high-temperature operation.
• What is the self-resonant frequency (SRF) of the inductor?
  The SRF of the DRQ74-100-R is typically around 150-200 MHz, but this can vary depending on the specific application and PCB layout. Consult Coiltronics' application notes or contact their technical support for more information.
• Can the inductor be used in a switching regulator application?
  Yes, the DRQ74-100-R is suitable for switching regulator applications, but the designer should ensure that the inductor is properly sized for the specific application and that the switching frequency is within the recommended range.
• What is the recommended storage and handling procedure for the inductor?
  Coiltronics recommends storing the inductors in a dry, cool place, away from direct sunlight and moisture. Handling should be done with care to avoid mechanical stress or damage to the component.
