Fixed inductors are electronic components that store energy in the form of an electrical current. They are used in many different types of electrical circuits and it is often necessary to have a wide range of fixed inductors available for a given application. The 78FR68K is a type of fixed inductor that is one of the most widely used inductors in the electronic component industry. It is a high-reliability, shock-resistant, and temperature-resistant type of fixed inductor.

The 78FR68K is a ceramic-based inductor that is composed of two or three layers of ceramic material, which are held together by an epoxy resin. The ceramic material is embedded in an epoxy ring which helps to protect the ceramic layers from external mechanical and temperature interference. The inductor coil is wound around the core, and this core typically consists of an inner core of iron, which is surrounded by a layer of air. The air layer helps to reduce the self-inductance of the inductor. The inner and outer cores are then sealed in a protective resin. The 78FR68K is available in different sizes, depending on application, and these can range from 75 mil to 2200 mil.

The 78FR68K is used most commonly in consumer and automotive applications, typically for frequency control. In this type of application, the 78FR68K fixed inductor is used to create a low-frequency signal that is used to tune the frequency of the operating device. Its high reliability and shock resistance make it suitable for high-load systems, and it is also suitable for pulse applications. The 78FR68K inductor is also capable of handling very high current levels, and it can withstand temperatures up to 150°C.

The 78FR68K fixed inductor is also commonly used in power supplies and in high-performance computer systems. In these applications, the 78FR68K is used as a stabilizer for the power supply system. Its temperature resistance makes it capable of withstanding high-temperature environments, which makes it particularly suitable for this type of application. The 78FR68K is also used to filter Radio Frequency (RF) signals and to provide protection against EMI interference. In addition to these applications, the 78FR68K can also be used in telecommunications systems and in RF applications to generate and control the power of the signals.

The working principle of the 78FR68K is based on the fact that when an electrical current is applied to the inductor, a magnetic field is generated. This magnetic field is used to store the electrical current in the form of an inductive reactance. The magnitude of the reactance depends on the size and number of layers of the inductor, as well as the number of turns in the coil. The reactance is used to resist the flow of current, and this resistance is the basis for the inductive operation of the 78FR68K.

In summary, the 78FR68K is a fixed inductor that is commonly used in consumer, automotive, power supply, and telecommunications applications. It is a ceramic-based inductor that is composed of two or three layers of ceramic material that is embedded in an epoxy-based ring. Its working principle is based on creating and maintaining an inductive reactance, which is used to resist the flow of current. The 78FR68K is a high-reliability, shock-resistant, and temperature-resistant inductor that is capable of withstanding temperatures up to 150°C.
