DR73-101-R Details

The recommended PCB land pattern for the DR73-101-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a 1.3mm diameter hole in the center for the pin. The pad should be solder-mask defined (SMD) with a non-solder-mask-defined (NSMD) connection to the pin.
The DR73-101-R has a maximum operating temperature of 125°C. To ensure reliable operation, keep the component away from heat sources, use a sufficient copper area for heat dissipation, and consider using a thermal via or heat sink if necessary.
The recommended soldering profile for the DR73-101-R is a reflow soldering process with a peak temperature of 260°C, a dwell time above 220°C of 30-60 seconds, and a total process time of 3-5 minutes.
Yes, the DR73-101-R is designed to withstand vibrations up to 10G. However, it's essential to ensure proper PCB mounting and secure the component to prevent movement or damage.
To ensure magnetic shielding, keep the DR73-101-R at least 5mm away from other magnetic components, and consider using a magnetic shield or a mu-metal shield around the inductor if necessary.
