Fixed Inductors

Inductors, also known as coils, are electrical components that store energy in the form of a magnetic field. Fixed inductors are special types of inductors that can be used in various ways, such as to provide voltage stabilization or to filter out certain frequencies. One such type of fixed inductor is the PT25R-900HM. In this article, we will discuss its application field and working principle.

Application Field of the PT25R-900HM

The PT25R-900HM is a fixed inductor that is well-suited for use in automotive, industrial, and consumer electronics applications. It can be used for power line filtering, such as in power supply circuits, and it also has high DC current handling capability, making it suitable for low power starter motors and alternators. This type of inductor also features high current-carrying capacity, making it ideal for use in high power motor drivers and other power circuits.

Working Principle of the PT25R-900HM

The PT25R-900HM inductor works by blocking high-frequency signals while allowing low-frequency signals to pass. This is achieved through the use of two coils, one on the primary side of the inductor and one on the secondary side. When a current is applied to the primary coil, it creates a magnetic field which induces a current in the secondary coil. This induced current is out of phase with the original signal, resulting in a signal being blocked at the secondary side while allowing lower frequency currents to pass.The frequency that can be blocked is determined by the inductance of the inductor and the value of the resistor in the circuit. Increasing the inductance will block higher frequency signals, while a lower inductance will block lower frequency signals. Additionally, increasing the value of the resistor in the circuit will also block higher frequency signals.

Benefits of the PT25R-900HM

The PT25R-900HM is a reliable and cost-effective fixed inductor that can be used in a wide range of applications. Its wide current-handling capability makes it suitable for use in high power motor drivers, automotive, and industrial applications. Additionally, the PT25R-900HM also has the benefit of providing accurate, repeatable signal filtering, making it an ideal choice for use in power supply circuits and other applications where accuracy and repeatability are important.

Conclusion

The PT25R-900HM is a versatile fixed inductor that can be used in many different applications. It has a wide current-handling capability and is well-suited for high power motor drivers, automotive, and industrial applications. Additionally, its ability to provide accurate, repeatable signal filtering makes it ideal for use in power supply circuits and other applications where accuracy and repeatability are important. In summary, the PT25R-900HM is an excellent choice for those looking for a reliable fixed inductor for their projects.
