Fixed Inductors

A fixed inductor, also known as a choke or coil, is an electrical device that increases the electrical resistance to a current, thereby limiting the amount of electrical current passing through the device. It is made up of coils of insulated wire encased in a box or shell.

The 4302R-102J is a fixed inductor used in both AC circuits and DC circuits. It has an inductance of 102 mH and an operating temperature range of -25°C to +55°C.

Application Field

The 4302R-102J is used in filter circuits for electronic applications. It is typically used in circuits that require a low impedance path for AC signals or a high DC resistance for DC signals. It can also be used in circuits to limit current spikes and generate inductive energy.

Other applications include: high frequency filtering, attenuation of interfering signals on AC power lines, protection circuits in battery operated appliances, regulates current in RF devices, used in high frequency oscillator circuits, and in switching power supplies.

Working Principle

When a current is passed through the 4302R-102J, it has the effect of generating an electromagnetic field in and around the coil of wire. This field acts like a magnet, creating an opposing force which opposes the current and prevents it from passing through the inductor. It is the opposing force created by the magnetic field that causes the current to decrease, limited or regulated.

The amount of opposition from the magnetic field will depend on the type of inductor, the amount of current, and the size of the inductor. The size and type of inductor determines the amount of current that can be limited or regulated.

Conclusion

The 4302R-102J is a fixed inductor used in filters for AC and DC circuits. It has an inductance of 102 mH and an operating temperature range of -25°C to +55°C. The inductor has many applications, such as high frequency filtering, attenuation of interfering signals on AC power lines, protection circuits in battery operated appliances, and more. It works by generating an electromagnetic field in and around the coil of wire, creating an opposing force which opposes the current and prevents it from passing through the inductor.
