DR73-4R7-R Frequently Asked Questions (FAQ)
-
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.
-
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.
-
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.
-
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.
-
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.
