HKQ04020N7S-T Working PrincipleThe working principle of the HKQ04020N7S-T fixed inductor is based on the concept of electromagnetic induction. The inductor consists of a coil of winding and a core material with a fixed air gap. When an electrical current passes through the winding, a magnetic field is generated. This magnetic field then induces an electromagnetic force, which opposes the current and increases the voltage across the inductor. This voltage is proportional to the rate of change of the current, which is known as inductance, and is measured in units of Henrys. The inductance of the HKQ04020N7S-T fixed inductor is stable regardless of temperature, making it suitable for a variety of applications. It also has a very low parasitic inductance, which reduces noise and increases system performance. Additionally, the leaded SMD structure provides easy integration and cost effective solutions for high reliability applications. The HKQ04020N7S-T fixed inductor is a highly reliable and highly efficient component that is suitable for a wide range of applications. Its high temperature range, wide current range, and low parasitic inductance make it a versatile option for applications that require continuous and reliable power delivery.
