Power supply inductor, high power inductors, high current inductors

 Reliable and efficient, power inductors are passive components that feature a tightly coiled conductive wire to create a magnetic field and store energy. They contribute to minimal signal loss, effectively filter EMI interference and maintain steady current flow making them the preferred option for circuit with varying voltage.
