Fixed inductors are devices used in electronic circuits to store electric energy in the form of a magnetic field. The TO1608-680M fixed inductor is specifically designed to meet the needs of demanding applications in power electronics and its applications are found in fields as diverse as consumer electronics, automotive, medical, military and more. In this article, the TO1608-680M application field and working principles will be discussed.

The TO1608-680M is a wire wound inductor with a ferrite core and a manganese zinc ferrite core. It features a wide, flat operating temperature range from -40°C to +85°C, low profiles, and the ability to withstand a maximum DC current, up to 2A. The inductance range is between 0.47uH to 470uH with a ± 20% tolerance. It is also RoHS compliant and is free of lead (Pb) and other hazardous materials, making it suitable for high reliability applications.

The TO1608-680M has a variety of application fields. It is widely used in power converters, DC-DC converters, switch-mode power supplies, inverters, switching regulators, and motor control systems. In addition, it can be used for noise reduction in signal line conditioning and in industrial applications where a reliable and efficient inductor is required. It can also be used for in-line noise filtering applications, such as in telecommunications. Another possible application of the TO1608-680M is in circuit testing and measurement equipment, such as oscilloscopes and analyzers.

The TO1608-680M has two main modes of operation that rely on the same principle: impedance and energy storage. When high frequencies are transmitted through the inductor, the device limits or filters the signal by storing energy in the form of a magnetic field in the core of the inductor. This function is known as impedance. When electrical frequencies increase, the inductance value of the inductor decreases, providing a "noise suppressor" effect. On the other hand, when low frequencies are passed through the inductor, the device stores energy in the magnetic field. This energy is released slowly and prevents fast changes in the voltages and currents, thus providing an energy storage capability.

The TO1608-680M can also be used to create a series of tuned circuits. In a tuned circuit, the inductor is combined with a capacitor to create a resonance frequency. By controlling the value of the inductance, the frequency of this resonance can be adjusted. This effect is used for a variety of applications, such as signal selection, filtering, and signal separation.

In summary, the TO1608-680M fixed inductor is a powerful and reliable device that has a wide range of applications in power electronics and more. It provides electrical design engineers with the flexibility to select a part that meets their specific requirements. Its ability to provide impedance and energy storage functions, as well as its compatibility with tuned circuits, make it an ideal device for many applications.
