Fixed Inductors are commonly used in a variety of electrical devices such as radios, televisions, amplifiers, and other types of electrical circuitry. In particular, they are used to provide the necessary impedance (inductance) to a circuit to allow it to work properly. The 4922R-20K is a specific type of Fixed Inductor that is particularly well-suited for use in high-performance electrical applications. This article will explain the application field of the 4922R-20K as well as its working principle.The 4922R-20K Fixed Inductor is a high-precision component that is designed for use in applications where accuracy and stability are crucial. The 4922R-20K is a surface-mount component that is compatible with the standard printed circuit board (PCB) mounting technology. It is designed for accurate stand-alone operation without additional matching components, and it provides excellent long-term stability and low temperature coefficients. In addition, the 4922R-20K has very low reactance, which ensures that it will not significantly degrade performance.The 4922R-20K is primarily intended for use in high-performance audio applications such as high-fidelity preamplifiers, active crossover networks, and advanced signal processing circuits. It is also suitable for use in precision timing circuits and in medical instrumentation. Its excellent performance characteristics make it well-suited for use in demanding applications such as military and aerospace, where accuracy and stability are essential.The working principle of the 4922R-20K is based on the principle of induction. An inductor is composed of a coil of wire that creates a magnetic field when a current passes through it. This magnetic field induces a voltage in the coil, which is then transferred to whatever circuit it is connected to. This voltage is proportional to the rate of change of the current, and is usually measured in Henrys (H).In the case of the 4922R-20K, the inductor is made up of a single-layer coil of heavy-gauge steel. This coil is wound in a tight, symmetrical pattern such that the magnetic field is evenly distributed throughout the coil. As current is passed through the coil, the magnetic field causes the core of the coil to become magnetized, which induces a voltage. This voltage is then transferred to whatever circuit the 4922R-20K is connected to.The 4922R-20K also features an internal resistance of 0.1 Ω (ohms). This is important, as it ensures that the inductor does not draw too much current from the circuit, which could potentially cause it to overheat or fail. As a result, the 4922R-20K provides reliable performance even in applications with high current demands.The 4922R-20K is an excellent choice for high-performance electrical applications due to its high precision and excellent stability. Its 0.1Ω internal resistance ensures that it does not draw too much current from the circuit, and its single-layer coil design provides an evenly distributed magnetic field for excellent induction. As a result, it is perfect for use in areas where accuracy and stability are essential, such as military and aerospace. Overall, it is a reliable and versatile inductor that can handle a variety of demanding applications.
