Fixed inductors are electrical components that are designed to provide a controlled amount of electrical resistance to the current going through them, with the main purpose of limiting this current to a predetermined amount. ELJ-FCR27KF is a type of fixed inductor that can be used in a variety of applications, and its working principle can be explained with the help of a simple analogy.

Consider a garden hose with a nozzle attached to it. If the nozzle is opened, the pressure at which the water is released from the hose can be regulated to different levels by controlling the size of the nozzle opening. In the same way, a fixed inductor functions to regulate the amount of current that passes through it in a circuit. It works on the principle that a magnetic field tends to resist changes in electric current. When adequate current is supplied to an inductor, it produces a magnetic field that causes a back-EMF (electrodynamic force) to be generated, which opposes the current flow.

The ELJ-FCR27KF fixed inductors are typically used for DC/DC, switching, regulator, and transformer applications. It is a high current, surface mountable, chip form inductor that has a low profile construction. This makes it suitable for use in small form factor applications. The rated inductance range is from 3.3nH to 27nH, and the maximum DC resistance is 0.04 Ω. The ELJ-FCR27KF is also capable of operating over a wide temperature range of -40°C to +125°C.

The maximum DC current range of the ELJ-FCR27KF is 0.1A to 0.45A and it can handle transient current up to 5.5A depending on the part number. Its uses are more limited than other types of fixed inductors because it is not designed to be used in power circuits. It is mainly used in logic circuits, such as in digital processors and other similar systems that require a high degree of accuracy and reliability.

The ELJ-FCR27KF is built with a ferrite core material, which means that it is prone to heat dissipation. This is why it should not be used in high power applications since it is likely to overheat under these conditions. To ensure safe operational temperatures, it must be operated within its specified temperature range. In addition, it should be kept away from environments with high levels of vibration, as this can cause the components of the inductor to become damaged.

The ELJ-FCR27KF is a versatile fixed inductor that can be used in numerous applications. Its ability to handle transient current up to 5.5A and operate over a wide temperature range of -40°C to +125°C make it a great choice for many types of projects. Its ferrite core construction also makes it suitable for use in logic circuits, where precision and reliability are key.
