DR73-4R7-R - COILTRONICS

DR73-4R7-R Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the DR73-4R7-R?
  The recommended land pattern for the DR73-4R7-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
• Can I use the DR73-4R7-R in a high-temperature environment?
  The DR73-4R7-R is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
• How do I handle the DR73-4R7-R during PCB assembly to prevent damage?
  Handle the DR73-4R7-R by the body, avoiding touching the leads or core. Use a vacuum pickup or tweezers to place the component on the PCB. Avoid bending or flexing the leads during assembly.
• What is the equivalent series resistance (ESR) of the DR73-4R7-R?
  The ESR of the DR73-4R7-R is approximately 0.15 ohms at 100 kHz, but this value can vary depending on the frequency and operating conditions.
• Can I use the DR73-4R7-R in a switching regulator application?
  Yes, the DR73-4R7-R is suitable for switching regulator applications due to its low core loss and high saturation current rating. However, ensure that the inductor is properly sized for the specific application and operating conditions.
