PT75R-1260HM

Fixed inductors are components which are composed of an iron core and physical winding assembly, that acts like a single electrical component. The PT75R-1260HM is an inductor of the fixed variety, and finds application in a variety of fields. This article will discuss the application field and working principle of the PT75R-1260HM.The PT75R-1260HM is a fixed inductor with a range of nominal inductance from 3μH to 3mH, a tolerance of ±20%, and current ratings up to 12A. It is suitable for SMPS and buck converters, low-inductance DC/DC converters, EMI and power line filtering, as well as PFC and low-profile motors. The product is intended for applications in automotive, industrial, and consumer products and is designed to withstand temperatures as high as 150°C.The working principle of the PT75R-1260HM is based on Faraday\'s law of induction, which states that the electromotive force (EMF) induced in a circuit due to a change in magnetic flux is equal to the time-rate of change of the flux. In the case of an inductor, a current-carrying conductor is wound to form a coil, which induces a magnetic field. When a change in current either entering or exiting the inductor is detected, a voltage is generated due to the passage of time and this voltage acts as an EMF in the opposite direction of the source. This is known as self-induction and acts as a dampening effect on the current, providing a lag between the cause and effect of the current change.The use of a fixed inductor ensures that a specific value of inductance is maintained regardless of the current fluctuations, allowing for more precise control of the electrical power. This also explains why the current ratings of the PT75R-1260HM are so high. The combination of the magnetic core and the number and composition of the windings makes it possible to create an inductor with a specific inductance and a greater ability to withstand higher current ratings.The use of a magnetic core also allows for better heat dissipation from the inductor to the surrounding environment. The way in which a coil of wire stores energy as a magnetic field also helps ensure that the inductor doesn’t overheat, allowing for better thermal performance.In summary, the PT75R-1260HM is a fixed inductor with a range of nominal inductance from 3μH to 3mH, a tolerance of ±20%, and current ratings up to 12A. It finds application in SMPS and buck converters, low-inductance DC/DC converters, EMI and power line filtering, as well as PFC and low-profile motors. The product works according to Faraday\'s law of induction, which states that a voltage is generated due to the passage of time in response to a change in current either entering or exiting the inductor. Its combination of magnetic core and winding makes it possible for the inductor to have a specific inductance and a greater ability to withstand higher current ratings.
