Fixed Inductors

Inductors are passive electronic components that are used to store energy in the form of an electromagnetic field. They are usually made from a coil of wire, although some other materials like powdered iron are also used. Fixed inductors are not adjustable in any way, and have a fixed value of inductance. The PTKM25-180SM is a type of fixed inductor that is used in various applications.

Application Field

The PTKM25-180SM fixed inductor is commonly used in a wide range of electronic circuits, such as switch mode power supplies, voltage regulators, decoupling, high-frequency inverter circuits, and more. It is designed with a high operating temperature range and has a wide frequency range and high current handling capabilities. This makes it ideal for use in high-power applications. In addition, this fixed inductor also has a low DC resistance and inductance drift over temperature.

Working Principle

The PTKM25-180SM fixed inductor works on the principle of electromagnetism. When a current is passed through a coil of wire, it produces a magnetic field. This magnetic field is stored in the core of the inductor as electromagnetic energy. When a current is applied to the inductor, the magnetic lines of flux, which were stored in the core, induce a voltage in the coil. This voltage is proportional to the rate of change of current (time derivative) that is passed through the inductor. This voltage is known as inductance, and is measured in henries.

The PTKM25-180SM fixed inductor is designed for use in high-power circuits. It features a high inductance value and low DC resistance. The operating temperature range is wide, and the inductance drift over temperature is lower than most other similar components. It is capable of handling high frequencies, and is also protected from saturation.

Conclusion

The PTKM25-180SM is a type of fixed inductor that is designed for use in high-power applications. It has a high operating temperature range, wide frequency range, high current handling capabilities, and low DC resistance. It works on the principle of electromagnetism, where a magnetic field is stored in the core of the inductor as electromagnetic energy and a voltage is induced in the coil when a current is applied. Thus, it is used in various applications, such as switch mode power supplies, voltage regulators, decoupling, and more.
