DR74-100-R Details

The recommended PCB land pattern for the DR74-100-R is a rectangular pad with a minimum size of 50 mils x 30 mils, with a non-solder mask defined (NSMD) pad shape.
The DR74-100-R's inductance value can vary with temperature. To minimize this effect, ensure the inductor is operated within its recommended temperature range (-40°C to +125°C) and consider using a temperature-compensated design.
The maximum current rating for the DR74-100-R is 10.5 A, but this can be affected by the operating frequency, temperature, and other factors. Always check the inductor's saturation current and temperature rise to ensure reliable operation.
Yes, the DR74-100-R is suitable for high-frequency applications up to 1 MHz. However, be aware that the inductor's impedance and losses will increase with frequency, affecting its performance.
To ensure proper soldering, use a soldering iron with a temperature of 250°C to 270°C, and apply a small amount of solder paste to the PCB pads. Avoid overheating the component or using excessive solder, which can cause damage.
