DR73-3R3-R Details

The recommended land pattern for the DR73-3R3-R is a rectangular pad with a size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
The DR73-3R3-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 DR73-3R3-R by the body, avoiding touching the leads or the core. Use a vacuum pickup or tweezers to place the component on the PCB, and avoid bending or flexing the leads during assembly.
The SRF of the DR73-3R3-R is typically around 150-200 MHz, but this can vary depending on the specific application and PCB layout.
While the DR73-3R3-R is suitable for high-frequency applications, its performance may degrade above 100 MHz. It's recommended to consult with Coiltronics or perform simulations to ensure the inductor meets the specific application requirements.
