Fixed Inductors
AISC-1812H-220K-T is a ceramic core bead inductor and belongs to the category of fixed inductors. The general purpose of this type of inductors is to restrict current flow to a certain value. A fixed inductor is a passive electrical element and is composed of a conductor, such as copper wire, wound around a core material. This winding generates a predominantly magnetic field and it is this magnetic field that creates the inductance of a given device.AISC-1812H-220K-T is a low-profile, high-stability, professional-grade inductor with a maximum current rating of 220K A. It has a tightly controlled inductance tolerance of only +/-5%, ensuring excellent performance in high-frequency applications. The inductor’s inductance range is between 1812H and 220K. This ceramic core bead inductor allows for higher currents than ferrite core bead inductors, and it offers much better performance at higher frequency ranges.When applying AISC-1812H-220K-T, it is necessary to take into consideration the self and mutual inductance of the overall system, as this affects the performance. As with any other type of inductors, the current frequency and magnitude of current affect the inductance of AISC-1812H-220K-T; thus, higher inductance values are achieved at lower frequencies and higher current magnitudes. In addition, a suitable core size is also required to achieve the expected inductance values. The operating principle of AISC-1812H-220K-T is based on the principle of mutual inductance. This means that when a current flows through the device, it creates a magnetic field. This magnetic field then induces a voltage across the inductor, which is opposite in polarity to the current that goes through it. This voltage then acts like a resistor, limiting the current flow, thus preserving the stability of the system. AISC-1812H-220K-T is mainly used in electrical and electronics applications, such as high-frequency switching and signalling circuits, audio amplifier circuits, radio frequency filters and oscillators. Its high current rating makes it suitable for power and related switching circuits as well. This type of inductor is also commonly used in AC power switching applications, particularly those with complex switching requirements.AISC-1812H-220K-T is a very versatile and reliable electric part. Its high performance, superior quality, and wide application field make it an ideal choice for all kinds of applications. With a competitive price and excellent build quality, AISC-1812H-220K-T is a great asset for any designs requiring high performance and reliability.
