Fixed Inductors: 4922-23H Application Field and Working Principle

Fixed inductors are electrical components that store energy in the form of a magnetic field which is generated when a current passes through it. The 4922-23H is a type of radial leaded fixed inductor specifically designed for industrial and consumer electronics. In this article, we will explore the application field of the 4922-23H, as well as discussing its working principle and associated considerations.

Applications & Uses

The 4922-23H fixed inductor is well suited for use in pulse transformers and several other high frequency applications – making this type of fixed inductor a popular solution for consumer electronic products. Manufactured with a metal core of core silicon steel or iron, the 4922-23H is also suitable for applications that require a DC bias. The DC bias therefore can be used for either AC or DC control of inductance values. Another use for the 4922-23H fixed inductor is common mode chokes. Common mode chokes are used in a variety of electrical applications, such as lightning protection or suppression of system noise such as electromagnetic inference (EMI). By integrating this device in the PCB design, the engineer may make use of its minimum component insertion heights for faster installations. A further use of the 4922-23H fixed inductor is in the, already mentioned, pulse transformer. Pulse transformers are commonly used for data and signal transmission. Due to the radial leaded design of the 4922-23H, it may easily be used as a pulse transformer filter in these sorts of circuits. In addition to these, other uses of the 4922-23H fixed inductor include, but are not limited to, power inverters, batteries, power sources and voltage regulators.

Working Principle

By definition, an inductor is simply a device that stores energy in the form of a magnetic field. The magnetic field is created when a current is passed through the device’s windings which are made from insulated conductors. The winding in the 4922-23H fixed inductor also has a core of silicon steel or iron, which increases the inductance of the device.The amount of inductance an inductor provides is a function of its core radius and the number of turns in the winding. If the current flowing through the winding increases, then the magnetic field generated by the winding will also increase, resulting in a larger amount of inductance. As with all electronic components, the design of the inductor must consider proper thermal management. Thus, the proper placement of other components such as heat-sinks and fans may be necessary to help cool down the inductor and associated electrical components.

Advantages and Considerations

The 4922-23H fixed inductor offers many advantages over other inductors. For instance, this particular inductor is easy to mount and includes a number of safety features, such as a metallic shield over its winding and an insulated core. The shield helps protect the winding from external electromagnetic interference, while the insulation prevents accidental shorting of the winding when it is installed.As mentioned earlier, the 4922-23H fixed inductor is suitable for a range of applications. Furthermore, its moderate power rating, wide frequency range and low loss characteristics make it well suited for applications such as transformers and chokes. When considering the use of the 4922-23H fixed inductor, several other considerations must be taken into account. For instance, its low self-resonance frequency requires a design that takes into account proper signal isolation and restriction of other frequency components. All of these factors must be factored into the overall design of the circuit.In conclusion, the 4922-23H fixed inductor is an effective solution for a variety of applications that require a reliable, high-power, low-loss and durable electronic component. The 4922-23H’s small size and wide frequency range make it an attractive option for industrial and consumer applications. With proper planning and consideration, the 4922-23H can provide reliable performance and years of service.
