Fixed Inductors

Fixed inductors, or fixed inductive components, are a type of electrical device used to store energy in an electrical field. They have the ability to resist changes in currents or magnetic flux due to an alternating current or magnetic field. They are essential components of circuits in a variety of applications, and are commonly used to restrict or manage the flow of electric current, as well as provide electromagnetic compatibility with other components.One particular type of fixed inductor is the PTKM25-30SM, which is a surface-mount or PCB based inductor component. The PTKM25-30SM is a high-performance, high-saturation inductor designed to provide a fixed inductive element for surface mount applications. The device features a extremely low profile design, making it ideal for use in space-constrained applications. In addition, the component has an exceptionally low series resistance (ESR) to limit any heating or power loss associated with the inductor.The PTKM25-30SM is available in various inductance values between 1.9uH to 22uH. It is suitable for frequencies ranging from 10kHz to 250kHz. This makes the component versatile and applicable to a wide variety of applications.The operating principle of the PTKM25-30SM is similar to other types of inductive components. When a DC current is passed through the inductor, it induces a magnetic field. This magnetic field is stored within the device and acts as a way of temporarily storing electrical energy. When the current level within the device is increased, the magnetic field also increases, causing an increase in the stored energy. When the electrical supply is suddenly removed, the magnetic field collapses and releases the stored energy in the form of a secondary current. Due to the high efficiency of the device, PTKM25-30SM inductors are suitable for use in a variety of applications, including power management circuits, DC/DC converters, flyback transformers, and resonant circuits. The component is also able to provide a very high energy storage capacity in both AC and DC circumstances. Furthermore, due to its low profile design, the PTKM25-30SM is highly compatible with circuit boards containing a variety of components and can be housed in small-sized equipment.Overall, the PTKM25-30SM is an excellent surface-mount inductor component that offers high performance and efficiency. Its wide frequency range and low resistance characteristics make it suitable for a variety of applications, such as power management, DC/DC converters, flyback transformers, and resonant circuits. In addition, its low profile design ensures compatibility with circuit boards, making it an ideal choice for space-constrained equipment.
