API Delevan provides a recommended PCB land pattern in their application notes, which can be found on their website. The recommended land pattern is 0.25 inches (6.4 mm) in length and 0.15 inches (3.8 mm) in width.
To prevent moisture-related issues, it's essential to follow proper storage and handling procedures. Store the components in a dry, cool place, and avoid exposing them to high humidity or temperature fluctuations. If the components are exposed to moisture, bake them in a dry oven at 125°C (257°F) for 24 hours to remove any moisture.
While the datasheet doesn't specify a maximum voltage rating, API Delevan recommends derating the voltage based on the operating frequency. As a general guideline, the maximum allowable voltage is 1.5 times the rated voltage at frequencies below 1 MHz, and 1.2 times the rated voltage at frequencies above 1 MHz.
The 4212R-7 is rated for operation up to 125°C (257°F). However, the inductor's performance may degrade at higher temperatures. If your application requires operation above 125°C, consider using a high-temperature version of the inductor or consulting with API Delevan's application engineers for guidance.
To minimize EMI, ensure proper PCB layout and routing, keeping the inductor away from noise-sensitive components. Additionally, consider using shielding or a metal can to enclose the inductor, and follow API Delevan's application notes for EMI reduction techniques.
