DR74-221-R Frequently Asked Questions (FAQs)

  • The recommended land pattern for the DR74-221-R is a rectangular pad with a size of 4.5mm x 3.5mm, with a non-solder mask defined (NSMD) pad shape.
  • The DR74-221-R has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal interface material (TIM) to improve heat dissipation.
  • The SRF of the DR74-221-R is not explicitly stated in the datasheet, but it can be estimated to be around 100-150 MHz based on the inductor's physical characteristics and similar products.
  • While the DR74-221-R is a robust component, it's essential to ensure proper mounting and securing of the inductor to prevent mechanical stress and vibration-induced failures.
  • Consider factors such as the operating frequency, current requirements, and desired inductance value when selecting an inductor. Consult the datasheet and application notes for guidance, and consider consulting with a Coiltronics representative if needed.
