DR74-2R2-R - Eaton

DR74-2R2-R Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the DR74-2R2-R?
  The recommended land pattern for the DR74-2R2-R is a rectangular pad with a size of 4.5mm x 3.5mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the DR74-2R2-R's sensitivity to temperature?
  The DR74-2R2-R has a temperature range of -40°C to 125°C. To handle temperature sensitivity, ensure proper thermal management, use a thermally conductive adhesive, and consider using a thermal interface material (TIM) if necessary.
• What is the maximum current rating for the DR74-2R2-R?
  The maximum current rating for the DR74-2R2-R is 2.2A. However, it's essential to consider the inductor's saturation current, which is typically 70-80% of the maximum current rating, to ensure reliable operation.
• How do I minimize radiated emissions when using the DR74-2R2-R?
  To minimize radiated emissions, use a shielded enclosure, keep the inductor away from sensitive components, and consider using a common-mode choke or ferrite bead in conjunction with the DR74-2R2-R.
• What is the equivalent series resistance (ESR) of the DR74-2R2-R?
  The ESR of the DR74-2R2-R is approximately 0.15 ohms. This value can affect the inductor's performance in high-frequency circuits, so it's essential to consider ESR when designing with this component.
