Fixed inductors, also known as choke coils, are electronic components that store energy in the form of an electric or magnetic field. SPD73R-472M is a type of fixed inductor. This article will discuss its application field and working principle.

Application Field

SPD73R-472M fixed inductors are widely used in many electronics, such as LCD TVs, audio players, mobile phones, and more. It is also often used in power supply circuits where its ability to store energy for a short period of time can be employed to control the ripple current, reduce noise and interference, and stabilize the steady state voltage. It is particularly useful in high-speed switching applications, where it can prevent spikes from being transmitted along a signal line.

Working Principle

SPD73R-472M fixed inductors work by rapidly changing the magnetic field generated when a current flows through it. This generates a voltage that is proportional to the rate of change of the current. This voltage opposes the current flow and results in the inductor opposing any changes in the current. This inductance allows the current to remain steady and therefore the device is useful for storing energy.

When a current is applied, the inductor is either “charging up”, if the current is increasing, or “discharging”, if the current is decreasing. In either case, the magnetic field generated by the current increases or decreases accordingly, and thus a voltage proportional to the rate of change is generated. This voltage opposes the current flow, effectively damping any changes in the current flow.

This same process occurs in reverse when the current is removed; the voltage generated by the inductor causes the current to decrease, allowing it to store energy during this process. SPD73R-472M inductors typically have a working voltage range of up to 6V and a working frequency range of up to 1MHz.

In summary, SPD73R-472M fixed inductors are useful for their ability to rapidly change a magnetic field when a current flows through it, which generates a voltage. This voltage opposes the current flow and dampens any changes in the current, allowing it to be used for storing energy. It is mainly used in power supply circuits, as well as in high-speed signal transmission applications.
