Power supply inductor, surface mount inductor, tdk inductors

Power inductors are important in applications where voltage conversion is necessary because they yield lower core losses. Power inductors are also used in order to store energy, provide lower signal loss in system design and filter EMI noise. A power inductor is an electronic component which receives as well as stores electrical energy by using a magnetic field.
