Fixed Inductors

Inductors are electronic components that are designed to store and release energy in the form of a magnetic field. The basic design of an inductor consists of a wire coil, wrapped around a central core material, usually a ferromagnetic material such as iron. The core material helps to increase the inductance by concentrating the magnetic field generated by the wire coil.

1008-681F Application Field and Working Principle

The 1008-681F is a fixed inductor made from low-loss ferrite toroidal core material. It has a flat top outer surface and the diameter of the core is 8mm. The inductance value of the 1008-681F is 10uH with a rated current of 2.1A. It is ideal for use in DC/DC converters, power amplifiers, EMC/EMI filters, wireless charging coils and other applications that require a high inductance value.

In electrical terms, an inductor stores energy in the form of a magnetic field. This is generated when an electric current passes through the inductor coil. When the current is changed, either increasing or decreasing, the resulting change in the magnetic field induces a voltage in the inductor which opposes the change. This effect is called inductive reactance and is the key principle behind the working of an inductor.

The 1008-681F is made from a low-loss ferrite core material which means it has very low losses when the inductor is in use. This means more of the energy stored in the magnetic field is utilized more efficiently, especially in applications such as DC/DC converters, which require a high inductance value. It also means that the inductor can handle higher currents without heating up too much, which makes it ideal for power amplifiers and wireless charging coils.

The 1008-681F can also be used in a variety of EMC and EMI filtering applications. As mentioned above, the core material of the inductor has low losses, which make it suitable for use in circuits that require low noise levels. The inductor can also be used to filter out high frequency signals, which can be generated by digital circuits. This helps reduce the effects of noise and interference on the electronic circuits.

The 1008-681F is a popular choice for a variety of applications due to its high inductance value, low losses and relatively low cost. It can be used in applications such as DC/DC converters, power amplifiers, EMC/EMI filters and wireless charging coils. It is also a great choice for EMC/EMI filtering applications due to its low losses, which help to reduce the effects of noise and interference on electronic circuits.
