Magnetic ring coil manufacturers can respond to winding inductors instead of multilayer ferrite chip inductor, and explain in detail the difference between the two

Magnetic ring coil manufacturers can respond to winding inductors instead of multilayer ferrite chip inductor, and explain in detail the difference between the two.


First of all, the magnetic ring coil manufacturers tell you what inductance can be divided into several categories, according to what way to divide, so that you have a common sense of the inductor this new thing. Inductors can be divided into four major categories from the manufacturing process, winding, laminated, braided and thin film chip inductors, commonly used are mainly wound and laminated inductors.


The former is the result of the miniaturization of traditional wound inductors. The latter is produced using multi-layer printing technology and stacking process.


The volume is smaller than the wound chip inductor.


Wound-type inductors: It is characterized by a wide range of inductance (mH ~ H), high precision inductors, loss is small (that is, large value of Q), allowable current, production process inherited strong, simple, low cost; There are restrictions on further miniaturization. The ceramic core wound chip inductor can maintain a stable inductance and a relatively high Q value at such a high frequency, and thus has a place in the high-frequency loop.


Magnetic ring coil manufacturers can answer the question of whether you can replace the winding inductance with the  multilayer ferrite chip inductor or replace the  multilayer ferrite chip inductor with the winding inductance when the same inductance value is used. These two are used as inductances, except for the inductor. What are the differences in the value of these issues? Can they really replace them?


Magnetic ring coil manufacturers believe that in addition to the most commonly used inductance value, inductors have the following common parameters: Intrinsic capacitance (related to resonant frequency, the operating frequency of the inductor is much lower than this frequency, otherwise there will be problems); quality factor ( Depends on the frequency-selective performance of the circuit, the larger Q, the smaller the power loss, the higher the efficiency, the better the frequency selection performance), and the rated current (the maximum allowable current in the inductor). Whether or not it can be replaced depends on the use of the environment. In areas such as high-current, high-frequency radios, and resonant circuits, many factors must be taken into account when replacing. It is best to try out samples in advance.


Therefore, according to magnetic coil manufacturers and other industries speaking, winding inductance instead of  multilayer ferrite chip inductor is not impossible, the key is to control the above factors in the same range of values
