This magnetic field is confined to the area within the coil, which is the area in which all of the inductor\'s energy is focused. When a voltage is applied to the inductor, a current is generated, the magnitude of which depends on the applied voltage, the inductance and the inductor\'s internal resistance.At higher frequencies, the inductor\'s internal impedance becomes more resistive and the energy is dissipated as heat, this is known as Loss. Therefore, at higher frequencies, the amount of energy that is transfer to the load is reduced. To reduce this, a shield is placed over the coil of the inductor to minimize the currents generated in the parasitic capacitances. As a result, it prevents the current from leaking into adjacent components and also reduces energy losses.ConclusionThe SLF12565T-150M4R2-PF is a surface mount inductor designed for high-frequency switching applications. It features a optimized magnetic circuit structure, and an external shield that provides high efficiency under high-frequency and heavy load conditions. The SLF12565T-150M4R2-PF is suitable for medium power applications and used widely in power supply, telecoms, automation, automotive, and audio systems.
