Different surface mount (SMD) inductor construction types are available to suit different needs including unshielded, shielded, low profile, and low EMI families. For compact densely populated board designs, as typical in new IoT designs, the shielded and low EMI inductors are good choices, since their magnetic flux is better contained within the inductor resulting in lower noise induced in surrounding PCB traces and components. For the highest efficiency and power handling, unshielded types can offer the best performance and are available in low profile.
