Fixed Inductors are electrical components that are used in a variety of electronic circuits and systems. Typical applications are used to provide high-frequency filtering, achieve extremely low-noise sections, provide surge protection, or control a wide range of frequencies for various applications. The most common type of fixed inductors is called the HK10052N7S-T. The HK10052N7S-T Application FieldThe HK10052N7S-T is mainly used in high-frequency interfering circuits, such as, frequency divider, digital-analog converters, etc. It is designed for use in very small area and connects directly to the traces on the PCB. The typical applications for the HK10052N7S-T include communication applications such as wireless transmitters, cellular transceivers, GPS modules, and digital TV tuners. The HK10052N7S-T is one of the most commonly used inductors due to its low power consumption and its ability to minimize noise interference due to its shielded structure. The metal shield reduces interference from external sources by decreasing the coupling of external energy into the internal environment of the inductor, allowing it to function efficiently and reliably.The HK10052N7S-T Working PrincipleThe HK10052N7S-T is a self-shielded inductor. Its main parts consist of an inner core, a wire winding, and a shield. The inductor’s winding is made of high-conductivity thin copper foil. This copper foil is connected to the PCB trace on one side and wound around the inner core on the other side. The shield, which is made of metallic material such as stainless steel or nickel iron, is secured around the body of the inductor. It acts as an electromagnetic barrier that reduces interference. The inner core consists of a ferrite material with many slots in which the wire winding are placed. The winding is a basic square-shaped helix with a varying number of turns depending on the inductance value of the HK10052N7S-T. The length of the turns is also varied according to the inductor value. When a voltage is applied to the conductor, an electric current is set up within the conductor. This current produces a magnetic field that is affected by the amount of turns of the wire. The helical windings act as a transformer by amplifying the magnetic field. The more the number of turns, the higher the amplified magnetic field, thus resulting in the induction of a greater effect.The shield also plays an important role in the HK10052N7S-T. It acts as an electromagnetic absorber that absorbs external electromagnetic energy by reducing the coupling of external interference into the inductor. This reduces noise levels in the circuit. ConclusionThe HK10052N7S-T fixed inductor is a type of component that is used in many electronic circuits and devices. Its high-frequency filtering capabilities, low-noise performance, and surge-protection features make it a very reliable and effective device. Its core and winding structure allows for efficient operation, while the metal shield reduces interference from external sources. With its wide range of application fields, the HK10052N7S-T fixed inductor is a common and reliable component for many applications.
