Fixed Inductors

Fixed inductors are components that are used in electronic circuits to store energy in the form of a magnetic field. Fixed inductors are commonly used in power supplies, in particular in high-frequency applications where fast switching and wide operating frequency are required. One of the most popular types of fixed inductors is the SP1008R-183G. It is athrough-hole device with an unshielded construction.

SP1008R-183G Application Field and Working Principle

The SP1008R-183G can be used in a wide variety of applications, such as high frequency switching, DC/DC converters, and filter circuits. It can also be used in a number of other applications such as power amplifiers, audio power amplifiers, and EMI/RFI filters.

The SP1008R-183G is a fixed inductor with a high inductance value of 8.2 mH with a maximum current rating of 0.4A. The device is rated with a temperature range of -40°C to +125°C and is packaged in a small surface mountable, molded plastic case. It is suitable for a range of frequency applications, from 10kHz to 1MHz.

The working principle of a fixed inductor is based on Faraday\'s law of induction, which states that a change in magnetic flux, induced by a changing electric current, causes the creation of an electromotive force (EMF). This EMF is opposite in direction to the change in magnetic flux and opposes the change in current. This effect results in energy being stored in the form of a magnetic field.

When an AC current is applied to an inductor, the induced EMF causes a resistance to the current, resulting in a decrease in the rate of current change. This resistance is known as inductance and provides a form of energy storage, allowing current to flow through the inductor without having to be constantly supplied by the power source. This stored energy also helps to stabilize the voltage across the inductor as the current fluctuates. This allows it to be used as a starting point in the design of filter circuits and amplifiers.

The SP1008R-183G is an ideal choice for a wide variety of applications, including high frequency switching, DC/DC converters, and filter circuits. Its high inductance, easy mounting, and wide operating temperature range make it suitable for use in a wide range of applications. It is important to remember, however, that the power dissipated by the device must be taken into account, as it can cause increased heat generation and reduce component life.
