The SP1008R-103H is an inductor produced by the AVX Corporation. It is a surface-mount fixed inductor constructed using SMD (Surface Mount Devise) technology. It is a radial leaded device with an inductance of 10–20uH. It is usually made from ceramic and is in a 7.7mm x 4.6mm x 8.8mm package with a rated current of up to 4.2A. The SP1008R-103H is designed primarily for DC-DC converters, high frequency rectification circuits, battery charging and life support circuits.

The inductor has a variety of applications in the areas of consumer electronics, industrial electronics, communications, aerospace, automotive, medical and telecommunications. It is an ideal component to add stability to power circuits. The SP1008R-103H is also suitable for power system snubber applications and electromagnetic interference (EMI) suppression. It is also widely used in switching circuits, filter inductors, transformers, and filter transformers.

The working principle of the SP1008R-103H is based on the production of a magnetic field by an electric current. A surface mounted inductor consists of several magnetic layers, which are wrapped in insulation. When an electric current is applied, a magnetic field is produced around the coil. This magnetic field interacts with the magnetic fields of the other layers producing an AC magnetic field. The AC magnetic field induces an electric potential difference in each of the layers, causing current to flow.

The shape and size of the inductor determines its advantages and disadvantages, such as its inductance and its current rating. Its small size allows it to be used in tight spaces, but can lead to problems with cooling and insulation. Its current rating is also a limitation when used for high power applications. The SP1008R-103H’s ceramic construction makes it resistant to vibration and shock.

The SP1008R-103H is a useful component in a wide range of electrical and electronic circuits. Its small size and reasonable current rating make it ideal for DC-DC converters, high frequency rectification circuits, battery charging and other power circuits. Its suitability for EMI suppression and snubber applications makes it a valuable component in many consumer, industrial, automotive, telecommunications and medical applications.
