Working Principle

The working principle of HKQ0603S18NH-T is based on Faraday\'s law of electromagnetic induction. When alternating current passes through the inductor windings, electromagnetic fields are generated around it, which in turn generates a voltage opposite the original current direction. In other words, when the primary winding of the current passes through the inductor, a voltage is generated in the opposite direction in the secondary winding. This voltage has two important properties: the magnitude of the generated voltage depends on the time derivative of the primary current, and the phase difference between the primary current and the generated voltage is always 90 degrees. This means that the inductor can provide the required impedance to maintain the operational current within a certain range.

In conclusion, the HKQ0603S18NH-T is a non-magnetic inductor widely used in the field of electroacoustics, communication, and automotive electronics. Its working principle is based on Faraday\'s law of electromagnetic induction, which can provide electrical parameters that can be regulated in the component itself. Thus, the inductor can be used in a variety of applications to ensure the operation of each system is within the required range.
