4r7 inductor
A component widely used in electronic circuits, the 4r7 inductor enjoys both precision and stability. Mainly for storing energy in a magnetic field, but also acts to smoothen, filter and isolate electronic signals its main purposes are functionally diverse. In terms of technology it has high saturation currents and low resistance, allowing it to give good performance even under conditions of high frequency operation. The smallness of its size means it can be used in designs requiring space efficiency such as on PCB boards. 4r7 inductors are used in a range of applications across different industries that include power supplies and inverters (industry), consumer electronic products such as mobile telephones, computers and communications equipment. *Some examples of this are speaker coils for portable audio systems.*
