Fixed Inductors

Fixed inductors are electrical components that can provide a known inductance value while restricting current flow in certain conditions. The SPD73R-123M is a type of fixed inductor that has a number of useful characteristics and applications.

The SPD73R-123M is an axial-style fixed inductor with three terminals and a maximum voltage rating of 13 VDC. The device has a nominal inductance value of 0.56 μH and a DC resistance of 0.122 ohms. It is made of a ferrite core material and is typically placed near a ground plane to reduce inductive coupling. The device is commonly used for energy storage, noise filtering, and EMI suppression.

The working principle of the SPD73R-123M is based on the fact that a varying current passing through the inductor will create an accompanying magnetic field. This magnetic field will induce a voltage between the terminals of the device which acts to limit the rate of current flow. As the current is restricted, the voltage drop across the device will be minimized. The amount of current which the inductor can handle is determined by its inductance value, which is fixed when the inductor is produced.

The SPD73R-123M can be found in a variety of electronic applications such as motor control circuits, signal processing circuits, radio transmitters, and portable electronic devices. It is also used in power supplies, inverters, switching circuits, and voltage regulator circuits. The device is well suited for high-frequency applications as it provides high performance at high frequencies, while also having low resistance characteristics. Additionally, the SPD73R-123M can be used in low power applications since its structure is small and light.

In summary, the SPD73R-123M is a fixed inductor and a useful component for many electronic applications. Its working principle is based on the fact that it limits current flow while providing a known inductance value to suit particular applications. The device has three terminals and can handle voltages up to 13 VDC. It is used in a variety of applications, particularly those that require high frequency response and good noise filtering properties.
