DR73-220-R - Eaton

DR73-220-R Frequently Asked Questions (FAQs)

• What is the recommended PCB pad layout for the DR73-220-R?
  The recommended PCB pad layout for the DR73-220-R is a rectangular pad with a minimum size of 50 mils x 30 mils, with a non-solder mask defined (NSMD) pad shape to ensure proper soldering and thermal relief.
• How do I handle the DR73-220-R's thermal considerations?
  To handle thermal considerations, ensure a minimum of 1 mm clearance around the inductor, avoid mounting components that may obstruct airflow, and consider using a thermal interface material (TIM) to improve heat dissipation.
• What is the maximum allowed voltage for the DR73-220-R?
  The maximum allowed voltage for the DR73-220-R is 250 Vrms, but it's recommended to derate the voltage based on the operating frequency and temperature to ensure reliable operation.
• Can I use the DR73-220-R in a high-temperature environment?
  The DR73-220-R is rated for operation up to 125°C, but it's recommended to derate the current rating and consider using a higher temperature-rated inductor or a custom design for extreme temperature environments.
• How do I ensure the DR73-220-R meets my specific application's requirements?
  To ensure the DR73-220-R meets your application's requirements, consult with Coiltronics' application engineers or perform thorough testing and characterization of the inductor in your specific circuit and operating conditions.
