Fixed inductors refer to electrical components that store energy as electromagnetic fields when current passes through them. They are widely used in various industrial and consumer electronics applications such as filtering, power supplies, circuit protection, and frequency-dependent signal conditioning. The primary purpose of an inductor is to offer electrical resistance and to reduce the negative effects of stray electrical signals that may disrupt equipment operation or upset a circuit. The most common applications of fixed inductors are digital signal processing, data conversion, RF communication, and audio and video processing.

100-121M inductors are a form of small size, fixed inductors used for signal processing applications. They are available in a variety of sizes and shapes, ranging from small surface mount packages to large, elongated power inductors. These inductors are designed with an advanced loop construction that provides excellent thermal stability and electromagnetic performance, allowing for higher currents and higher frequencies with lower losses. Because of their small size and high-frequency performance, they are often used in circuits with high current requirements and/or high signal bandwidths.

In terms of application fields, 100-121M inductors are widely used in switching power supplies, computers, telecom systems, and UPS, among others. They are also commonly found in the efficient design of DC/DC converters (such as buck, boost, and buck-boost converters), and are often used in the design of ultra-wideband amplifiers, high-frequency DC/DC converters, and high-performance switch mode power supplies.

The working principle of fixed inductors is based on Faraday\'s law of induction, which states that when an electrical current passes through an inductor, it creates an electromagnetic field. This field creates a secondary voltage in the form of an electromotive force (EMF), which is opposed to the primary current. The induced EMF is proportional to the rate of change of the primary current, thus producing a resistive component in the circuit. This resistance is called inductive reactance, or inductance, and it is the amount of opposition offered by the inductor to AC.

The 100-121M inductors offer several advantages, including high frequency switching and high current ratings, making them an attractive choice for a wide range of applications. They feature a low-profile design with a high saturation current, allowing for high-current operation at higher frequencies without causing excessive heat generation. They also provide superior high-frequency performance compared to standard ferrite inductors, as well as better temperature stability and magnetic noise immunity. Finally, these inductors are available in various sizes, shapes, and package types to meet the demand for different application scenarios.
