Old electrician engineer teach you how to choose power transformer type and to calculate transformer capacity. Power transformer is the key equipment in the power supply system, its main function is t

Features: Fully transformer printed circuit board is directly welded and installed, beautiful appearance, small installation height, compact structure, sturdy, moisture-proof, flame retardant, high e

The difference between I- type inductor and SMD winding inductor the most basic difference is that the patch winding inductor is patch type without pin, I-word inductor is plug-in type with pin, wave

What is the relationship between the inductance value and the air gap of the ferrite core? So the larger the air gap of the magnetic core, the lower the permeability and the smaller the inductance.

As we all know, an isolation transformer is a transformer with electrical isolation between the input winding and the output winding. Its structure, like other toroidal transformers, uses toroidal cor

When designing a new model, if we need to use a chip power inductor, how should we select it? We can judge from the following aspects.

selection of common mode inductance parameters 1. Input current. 2. Frequency. 3. Impedance.

What is the inductance represented by 2r2,4r7 and 6r8 on the chip inductor?

Inductor is an element that can convert electrical energy into magnetic energy and store it. The structure of inductor is similar to that of transformer, but there is only one winding. The inductor ha

Introduction to basic knowledge of transformer The transformer is composed of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power

Metal soft magnetic powder cores have been quickly and widely used in various scientific and technological fields and industrial fields because of their superior characteristics to other soft magnetic
