Introduction to Fixed InductorsA fixed inductor is an electronic component with a certain shape of copper wire or iron core as its conduction medium, which is mainly used to store energy or transmit signals. Most inductors are composed of windings of insulated wire or cores made of iron or ferrite (a ceramic-like material with high permeability) around a ferromagnetic core. In some inductors, the windings are built in layers in order to reduce their volume. The inductor in its simplest form is a coil of wire, however its useful properties do not come only from its coil of wire. Magnetic fields and core materials play important roles in its electrical properties.IMS05BH122KIMS05BH122K is a small-size fixed inductor produced by Shenzhen IMSAX Electronics Co., Ltd. It has a light weight, low profile and good heat dissipation.The IMS05BH122K is a low-current, low-profile, and broadband inductor with a rated current of 0.15A at 25°C and an inductance range of 0.125mH to 5.6mH @ 10kHz and 0.2mA. It is rated for operation temperature between -40°C to 85°C and an operating frequency from 0.1MHz to 10MHz.It is suitable for a wide range of applications, including DC/DC converter, power-line filtering, general EMI/RFI suppression, automotive, and others. The product can be used in pulsed operation with peak currents up to 0.8A.Application FieldThe IMS05BH122K is a great choice for high frequency DC-DC converters, power line filters, EMI/RFI suppression, automotive and other applications that need high frequency and high current operation. It is also suitable for frequency switching, common-mode filtering, bias winding, and other applications.The IMS05BH122K can also be used as an adjustable inductor. With the addition of a variable resistor, this inductor can be adjusted to obtain the desired inductance. This is a great advantage because it allows for more versatile applications, such as power line and noise suppression.Working PrincipleThe IMS05BH122K is an inductor with a simple construction which consists of windings of insulated copper wire around a core of ferrite or iron. The core prevents too much electrical energy from passing through the inductor, while the insulated copper wire acts as an electrical conductor for the current.The inductor works by reacting to the flow of current into it; this reactance to the current flow increases proportionally with the frequency of the current. This reactance generates an opposing voltage, which causes a voltage drop across the inductor. This voltage drop is usually equal to, but opposite in direction from, the applied voltage. This phenomenon is known as back EMF or counter EMF.In addition, the IMS05BH122K has a significant self-resonance frequency which is important when selecting an inductor for specific applications. Self-resonance is the frequency where the impedance of the inductor becomes a minimum and can be affected by the size of the inductor, the core material used and the number of windings.ConclusionIMS05BH122K is a small-size fixed inductor produced by Shenzhen IMSAX Electronics Co., Ltd. It has a light weight, low profile and good heat dissipation with a wide range of applications, such as DC/DC converter, power-line filtering, general EMI/RFI suppression, automotive, and others. The product is also suitable for use as an adjustable inductor, making it even more versatile. It works by reacting to the flow of current, generating an opposing voltage, and has a significant self-resonance frequency which is important for specific applications.
