The skeleton of the I-inductor is supported by the winding of the copper core coil. I-inductance is one of the attributes of an electronic circuit or device that refers to: When the current changes, the electromotive force that resists the current change due to electromagnetic induction Some large fixed inductors or adjustable inductors (such as oscillating coils, choke coils, etc.), the commonly used I-inductors are regarded as the vertical version of axial inductors, which is convenient to use and similar to axial inductors, but the commonly used I-inductors can have a larger volume of inductors. The current can also be applied to a certain extent; Most of them are enameled wire (or gauze wire) directly wrapped around the skeleton, and then the magnetic core or copper core, iron core, etc. is loaded into the inner cavity of the skeleton to improve its inductance. The skeleton is usually made of plastic, bakelite, ceramic, and can be made into different shapes according to actual needs. Small inductors (such as I-inductors) generally do not use a skeleton, but directly wrap the enamelled wire around the magnetic core.
H-shaped inductor coils are generally composed of magnetic or iron cores, frameworks, winding groups, shielding covers, packaging materials, etc.
