Fixed Inductors are components that store energy in the form of a magnetic field in order to control current in a circuit. The PT150-1250-VM is an example of an application-specific, fixed inductor. In this article, we\'ll discuss the application field and working principle of the PT150-1250-VM.The PT150-1250-VM is a high-efficiency, high temperature-resistant inductor that is designed to be used in 3.3V DC-DC buck converters, a type of switch-mode power supply. The inductors are used to reduce the ripple in the output voltage and provide better overall regulation.The PT150-1250-VM consists of a metal core with a length of 12.5 mm, the diameter of the coil is 6.6 mm, and the total height is 15.3 mm. The core material is made of high-temperature ferrite material is 67-55-12. The inductance is 150 uH, and the rated current is 1.2A. The resistance is 0.37 ohms. Finally, the maximum temperature rating for the inductor is +105 degrees Celsius.The working principle of the PT150-1250-VM is based on Faraday\'s law of induction, which states that when a flux of magnetic field, or current, changes, an electromotive force is induced. In the case of the PT150-1250-VM, the changing current creates a magnetic field in the core material, which induces a voltage across the terminals of the inductor.The electrical characteristics of the PT150-1250-VM are determined primarily by three factors: the size of the coil, the number of turns, and the core material. By increasing the number of turns, the inductance of the coil increases. The core material affects the impedance, meaning the higher the impedance, the more efficiently the inductor resists the changes in the current.The PT150-1250-VM is designed for applications that require high efficiency and high temperature resistance, such as in 3.3V DC-DC buck converters. The high efficiency of the design ensures that the output voltage is well-regulated and has low ripple.In conclusion, the PT150-1250-VM is a high-efficiency, high-temperature fixed inductor designed for use in 3.3V DC-DC buck converters. Its ability to resist high temperatures and efficiently regulate current makes it an ideal choice for such applications.
