9220-16

Fixed Inductors

Fixed inductors are passive components used to induce a voltage in a conductor or to limit the amount of current through another component. The specific inductor being discussed in this paper is model 9220-16. This model is composed of two polymer-coated ferrite cores with various taps for varying current needs. This specific inductor is optimized for use in high power applications.

Application field

Model 9220-16 is specifically designed to be used in induction heating applications. This type of application uses an alternating current, usually alternating at a frequency ranging between several kHz to several hundred kHz, through a conducting material which is appropriately shaped so that it can create a desired shape or temperature profile in the material. Because this type of induction heating uses high frequencies, model 9220-16 is optimized to provide a reliable, high-quality inductance across the entire range of operating frequencies.

Additionally, model 9220-16 can be configured for use in telecommunications, power transmission, and other high power radiofrequency applications. In these applications, the inductor is used to compensate for and limit current values in an alternating current, and can be adjusted for use with various components and frequencies.

Working principle

The working principle of the model 9220-16 is much like any other type of inductor. In an alternating current, an alternating voltage is created through the inductor when a buildup of charges is formed at the component’s terminals. This stored energy is known as inductance, and influences the flow of current in much the same way as resistance. The model 9220-16 is designed to capitalize on this effect as it is integrated with two polymer-coated ferrite cores, which increase the inductor’s efficiency at higher frequencies.

This inductor is capable of packaging two inductors in one component, allowing for a wide-range of inductance values. A variety of high-frequency applications - from telecommunications to power transmission require that inductance values be changed to optimize the performance of various circuits. The model 9220-16 allows for this kind of flexibility.

Additionally, due to the inductors construction of two polymer-coated ferrite cores, it has the added benefit of improved thermal characteristics compared to some other types of inductors. This quality makes it useful in applications where current and voltage levels can change rapidly and frequently.

Conclusion

The model 9220-16 fixed inductor is optimized for use in high power applications such as induction heating, telecommunications, and power transmission. It is composed of two polymer-coated ferrite cores, which effectively increases the inductor’s efficiency. It is also capable of packaging two inductors in one component, allowing for varying inductance values across a wide range of frequencies. This combination of features makes this model a suitable choice for many high power applications.
