SD3814-6R8-R

Fixed inductors, or inductors, are passive electronic components that consist of a coil of insulated copper wire wrapped around a center core of metal such as iron or ferrite, which stores energy in the form of a magnetic field. The SD3814-6R8-R is an inductor with a resistance value of 6.8R, a maximum voltage of 40V and a width of 2.6mm. It is a surface mount device, meaning that it can be soldered directly to the surface of a printed circuit board or other substrate without the need for additional mounting hardware.

The application field of the SD3814-6R8-R is very wide. It is used in applications where a high-frequency resonant circuit, such as a filter, is required. Due to its low series resistance, the inductor is often used to create noise or emi cancellation. It is also commonly found in DC-DC converters for power management systems, as well as in analog or digital signal processing systems.

The working principle of the SD3814-6R8-R is based on Faraday’s law of induction, which states that a changing magnetic field will induce an electric field, and vice versa. As the current flows through the inductor, a magnetic field is created. This field, in turn, induces a voltage in the coil, which is in opposition to the current flow. This voltage is known as the back EMF, or counter-electromotive force. This opposing voltage effectively reduces the current, resulting in a situation of stability. This is known as the inductive reactance of the inductor.

The SD3814-6R8-R is capable of managing up to 40V and 5A of continuous current, with a limited peak current of 20A. This makes it suitable for use in a variety of applications, from filters to high-current DC-DC converters. Thanks to its low series resistance, the SD3814-6R8-R is able to maintain a low thermal profile, resulting in more efficient and reliable operation in most applications.

In conclusion, the SD3814-6R8-R is a versatile and reliable fixed inductor. Its wide application field and working principle based on Faraday’s law of induction make it suitable for a variety of applications. Thanks to its low series resistance and high current capacity, it is ideal for power management systems as well as noise or EMI cancellation in both analog and digital signal processing systems.
