Fixed Inductors play a major role in many electronics applications. The SD3118-3R3-R is an example of a fixed inductor which, when incorporated into a circuit, works to achieve certain desired characteristics. In this article, the application field and working principle of the SD3118-3R3-R will be discussed.

Fixed inductors are passive components used to store energy in the form of a magnetic field. This magnetic field is created when current passes through the active element of the component, typically made of windings of wire around a core material. The SD3118-3R3-R is an example of a fixed inductor, which can be used in circuits to filter, couple, and decouple signals.

The SD3118-3R3-R is rated with a inductance value of 3.3 uH, a max dc current of 18A and a rated dc current of 10.3 A. It also has a high-temp rating of 125°C and a low-temp rating of -55°C. These characteristics make the SD3118-3R3-R well suited for a wide range of applications, including automotive, industrial and consumer electronics.

Typically, the working principle of fixed inductors is based on Faraday’s Law of induction. As current passes through the windings of the active element, a magnetic field is created which induces a voltage in the opposite direction to the flow of current. This induced voltage is known as “back-emf” and is used to filter or couple signals in the circuit.

In addition to these basic functions, fixed inductors can also be used to provide DC-DC conversion, frequency filters, voltage dividers, and noise suppression. The SD3118-3R3-R is especially well-suited for DC-DC conversion, as it can provide high inductance, low losses, and high current capabilities. Additionally, the SD3118-3R3-R is also widely used in applications such as motor drives, solar panel inverters, and power supplies.

To summarize, the SD3118-3R3-R is a fixed inductor used in many electronics applications. It is rated with a inductance value of 3.3 uH, a max dc current of 18A and a rated dc current of 10.3 A, and its operation is based on Faraday’s Law of induction. It can be used to filter, couple, and decouple signals as well as for DC-DC conversion, frequency filters, voltage dividers, and noise suppression.
