Fixed inductors are passive electronic components used to store electrical energy in an electromagnetic field. The PD105R-123K is one example of a fixed inductor. It is a surface-mountable, mid-range power inductor designed for low ripple and low volume applications. This particular type of fixed inductor is used in power supplies, motor controls, and other high-power applications where low noise and/or low voltage is required.

Application Field

The PD105R-123K is ideal for use in power supplies, motor controls, power amplifiers, and other high-power, low voltage applications. It can be used in AC and DC applications, and is designed to work with a specific frequency range. The PD105R-123K is particularly well-suited for high current applications and is highly efficient. It has a low ripple voltage and is designed for a low noise environment.

Working Principle

The PD105R-123K is a surface-mountable, axial-leaded fixed inductor. The main component is an inductor made of highly conductive materials such as copper, aluminum, or steel that is wound in a coil. The inductor stores electrical energy in the form of an electromagnetic field. When a current passes through the inductor, the magnetic field around the inductor increases. This increase in the magnetic field causes a voltage drop across the inductor, resulting in a decrease in the current. The current is reduced by an amount proportional to the inductance of the inductor. This is known as inductive reactance.

In addition to its inductive reactance, the PD105R-123K also takes advantage of the negative resistance effect of magnetic fields in order to reduce the overall power consumption of the device. This effect is known as self-resonance, and it results in an oscillation of the current and voltage in the circuit. The inductor is able to reduce the current in a controlled manner without damaging the circuitry.

The PD105R-123K is also designed to be highly efficient. Its winding is made from high-grade material to reduce losses and increase current carrying capacity. It also has an internal shield to protect the components of the device from external interference. The PCB is also designed to dissipate heat quickly, ensuring that the inductor stays cool and operates efficiently.

In summary, the PD105R-123K is a fixed inductor that is designed for low ripple, low volume applications. It is suitable for a variety of applications, including power supplies, motor controls, and high-power, low voltage applications. It has a high efficiency and low noise operation. Additionally, its self-resonance effect reduces the overall power consumption of the device. The PD105R-123K is a valuable component for many electronic applications.
