Coilcraft recommends a land pattern with a pad size of 2.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad and a 0.5 mm x 0.5 mm thermal pad in the center.
To ensure reliable operation, use a sufficient copper thickness (e.g., 2 oz or 3 oz) and a wide enough trace width to handle the high current. Also, consider using a heat sink or thermal vias to dissipate heat.
The SRF of the S5499-DLD is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, it falls in the range of 10-50 MHz.
The S5499-DLD is rated for operation up to 125°C, but its performance may degrade at higher temperatures. If your application requires operation above 125°C, consider using a different inductor or consulting with Coilcraft's application engineers.
Choose an inductor value based on your application's specific requirements, such as the desired inductance, current rating, and frequency of operation. Consult Coilcraft's inductor selection guides or application notes for more information.
