● The inductance is suitable for woofer circuits.
● It can be used for main circuit or bypass circuit.

 

BL stacked inductor is an important electronic component, and its production process involves multiple steps and materials.

 

The production process of BL stacked inductor mainly includes the following key parts:

 

Material selection: NiCuZn soft ferrite magnetic material is mainly used. This material has different initial magnetic permeability, which is conducive to the production of high-inductance inductors. The resistivity, specific surface area, particle size distribution and other characteristics of the material have an important influence on the performance of the inductor.

 

Production process: It involves the use of organic resin, organic solvent and other materials. At a temperature of 50~80 degrees, the resin is dissolved by organic solvent to form the required inductor structure.

 

Performance indicators: The performance indicators of stacked chip inductors include Q value (quality factor) and self-resonant frequency. Q value is a measure of the relative loss of inductance, and self-resonant frequency is the frequency point at which the distributed capacitance and inductance of the inductor resonate. ‌

In addition, multilayer chip inductors also involve the understanding of some professional terms, such as: ‌

Ferrite: a non-metallic magnetic material prepared by ferric oxide and other oxides through a ceramic production process. ‌

Soft ferrite: a ferrite with a narrow and long hysteresis loop, high magnetic permeability, and low coercive force, used to make inductive components. ‌

Magnetic flux: in a magnetic field, the product of the magnetic induction intensity and the direction perpendicular to the magnetic field, that is, the magnetic flux. ‌

Magnetic medium: a mixture of magnetic materials and dielectric materials. ‌

Electromagnetic shielding: a measure used to suppress radiation interference and high-frequency conducted interference. ‌

The production process of BL multilayer inductors involves a variety of materials and professional production technologies to ensure that the performance and quality of the final product meet the standard requirements.
