How to classify the inductance _Inductance coil _ electromagnetic coil introduction

How to classify inductance
First, sort by layout:
Inductors can be divided into wirewound inductors and non-wire wound inductors (multilayer chip, printed inductor, etc.) according to their layout. They can also be divided into fixed inductors and adjustable inductors.
Second, according to the placement method:
There are chip inductors and plug-in inductors. The shielded inductor is externally shielded from the inductor, and the exposed coil is often referred to as an unshielded inductor. Fixed inductors are also divided into hollow electronic sensors, core inductors, core inductors, etc. According to their layout shape and pin method, they can also be divided into vertical co-directional pin inductors and horizontal axial pin inductors. , large and medium inductors, petite inductors and chip inductors. The adjustable inductor is further divided into a magnetic core adjustable inductor, a copper core adjustable inductor, a sliding contact adjustable inductor, a series mutual inductance adjustable inductor and a multi-tap adjustable inductor.
Third, according to the operating frequency classification:
Inductance can be divided into high frequency inductors, intermediate frequency inductors and low frequency inductors according to the operating frequency. Hollow inductors, core inductors, and copper inductors are typically intermediate or high frequency inductors, while core inductors are mostly low frequency inductors.
Fourth, according to the classification:
Inductors can be classified into vibration inductors, proofing inductors, kinescope deflection inductors, choke inductors, filter inductors, barrier inductors, and compensated inductors.
The vibration inductor is further divided into a TV line vibration coil, a thing pillow shape proof coil, and the like. The kinescope deflection inductor is divided into a row deflection coil and a field deflection coil.
The choke inductor (also known as the choke) is divided into a high-frequency choke coil, a low-frequency choke coil, a choke coil for an electronic ballast, a TV line frequency choke, and a TV airport frequency choke.
The filter inductor is divided into a power supply (power frequency) filter inductor and a high frequency filter inductor.
