Fixed inductors refer to electrical components that are composed with one or more inductors. In modern electronic circuit designs, they are used as both static and dynamic compoents to filter, limit, store and process electrical signals. One typical type of fixed inductor is the SD3814-680-R, which is widely used in digital systems, medical equipment, communications, and automotive industries. This article introduces the application field and working principle of SD3814-680-R.

SD3814-680-R is a surface-mountable inductor with a wide operating range and high performance. With a 3.8 milliohms internal resistance and a 0.15uH inductance value, it can withstand a maximum current of 680mA and a maximum voltage of 20V. Thanks to its unique construction, the parts features a reliable performance in terms of low-resistance, low-field noise and low-temperature drift. It can be used in a variety of digital circuits and electronic device, particularly in high-frequency systems where the performance and reliability of the inductor is of critical importance.

The working principle of the SD3814-680-R is based on the Faraday’s Law of Induction. When an external alternating current is applied to the inductor, a magnetic field is generated, and the generator of that magnetic field is the inductor itself. This magnetic field produces a continuous electromotive force in the inductor, which in turn drives the current in the circuit. The intensity of the magnetic field can be regulated by controlling the intensity of the alternating current.

Furthermore, the operation of the SD3814-680-R can be divided into two processes: induction and damping. Induction occurs when the alternating current stimulates the electromagnetic field of the inductor. The generated magnetic field creates an electromagnetic force in a direction orientated to the changes of the alternating current, causing an electromagnetic induction process which induces a current in the coil. Damping, on the other hand, takes place when the alternating current ceases to generate a significant electromagnetic field in the inductor. This reduces the induced current in the circuit, thus providing the inductor with a dampening effect.

The SD3814-680-R is a versatile fixed inductor for a variety of electronic applications. It is cost-effective and has a high degree of reliability, making it a popular choice among professional and hobbyist electronic equipment users. With its superior performance and wide range of uses, the SD3814-680-R is a solid choice for any type of digital system, medical equipment, communications networks and automotive industry applications.
