Let's break down the information:

100?H: This indicates the inductance value of the inductor, measured in Henrys (H). Inductance is a measure of an inductor's ability to store energy in a magnetic field when current flows through it. 100?H means 100 microhenries.

I-Shaped Magnetic Core: The "I-shaped" core refers to the physical shape of the magnetic core around which the wire is wound. This core is usually made of a magnetic material like iron or ferrite, and it enhances the inductor's ability to store energy efficiently.

8x10 mm: These are the physical dimensions of the inductor. It's 8 millimeters in width and 10 millimeters in length. This indicates the size of the component, which is important for fitting it into a circuit or on a circuit board.

Hole Mount: This indicates the method by which the inductor is mounted onto a circuit board or other surface. A hole mount means that the component has leads or pins that are meant to be inserted into holes on a circuit board, and then soldered in place to secure it.
