PRODUCTION DATA
Always try to use a low EMI inductor with a ferrite closed core. Some examples would be toroid and encased E core inductors. Open core can be used if they have low EMI characteristics and are located a farther away from the low-power traces and components. Make the poles perpendicular to the PCB as well if using an open core. Stick cores usually emit the most unwanted noise.
