Fixed inductors, understood also as chokes, are components designed to create a magnetic field when electrical current passes through them. The CI201210-68NJ is a type of fixed inductor, displaying properties such as high inductance, low resistance and excellent temperature stability. In the following sections, the application field and working principle of this device will be explained.

Application Field

The CI201210-68NJ generally found application in the fields of power supply systems, communication systems and telecommunications. PID control systems, wireless base stations and RCD protection make up the majority of its respective uses. In addition, its use can be extended to military applications as its resistance to temperature variation is excellent. An example of this would be the utilization of such chokes for LED circuits. In this way, the self-heating effect of the LEDs, along with the temperature variation induced by the power supply, will not affect the choke’s performance.

Working Principle

The electrical current flowing through the CI201210-68NJ generates a magnetic field, such that the current itself will be restrictively travelling through the external circuit. This principle is known as theproperty of inductance. As stated above, the device possesses a high inductance and lower resistance. This causes the current to encounter a higher level of impedance than if it was traveling through a regular lead, the consequence of such property being a higher voltage drop in the external circuit.

The self-heating in these devices is another concern when deciding if they are appropriate for a certain application field. As current flows through the CI201210-68NJ a certain amount of heat is dissipated. This implies that, in certain circuits, the frequency is higher and thus, inducing more heating than the device can handle. As such, exceeding duty-cycles or pulse-durations must be veriefied, so that the device does not overheat.

Conclusion

In conclusion, the CI201210-68NJ fixed inductor is a perfect fit for most power supply and communication systems. Its high inductance and resistance to temperature variation make it ideal for a variety of applications, ranging from military to industrial. Furthermore, since these devices generate their own heat, the frequency of the current passing through them must be taken into consideration in order to prevent overheating and ensure the device’s durability.
