Inductor selection analysis, let's understand together
Feb 27 , 2021
You should be clear about the scope of inductance in the power circuit. Since the inductance is mostly not stable during the entire working period of the components, it is particularly important to grasp the scope of the effective value. For inductors used in power switching applications, the overall goal of allowable harmonic distortion current and transient response will determine the inductance...

Be aware of these tips when using inductors
Feb 27 , 2021
The main uses of RF inductors are diverse, and can be used in various structural features to consider performance testing schemes for special applications. Matching, resonators and choke coils are the main common uses of inductors in RF power circuits. Matching includes removing the characteristic impedance mismatch and minimizing the reflective surface and loss of the middle route of power circui...

Talk about why inductance can eliminate EMC
Feb 27 , 2021
Filtering power capacitors, common mode inductors, and magnetic beads are common shadows in the power supply circuit of EMC design schemes, and they are also the three major artifacts for solving interference signals. Regarding the effects of these three in the power circuit, I firmly believe that many technical engineers do not understand. The content of the article analyzes the basic principles ...

Knowing this knowledge is very useful for using one-piece inductors
Feb 27 , 2021
One-piece inductors are also called: Molded inductors include magnets and windings themselves. Surface-mount inductors. The key difference from general output power control inductors depends on the fact that one-piece inductors have a winding first, and then The metal is formed by die-casting of powdered and filled aluminum with magnetic material, and the leads are drawn out from the side and then...

The situation of China inductor market this year
Feb 27 , 2021
1. Overview of inductors Inductors are electronic components that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only blocks the change in the amount of current. If the inductor has no current through it, it will try to block the current throug...

Let us learn about these kinds of inductors
Dec 17 , 2020
The inductor will have a blocking effect on the current passing through the inductor under the condition of alternating current. The higher the frequency of the inductor, the greater the blocking effect. This type of condition is called inductive reactance and is measured in ohms (Ω). Said. Inductor characteristic 2: The current passing through the inductor will not change suddenly, the current wi...

Principle and main function of transformer
Dec 17 , 2020
Current transformer is an electronic component that can convert electrical energy into magnetic energy, store it under appropriate conditions, and release it and then convert it into electrical energy. The most important role of inductor is electromagnetic conversion. All electrical conductors (transmission lines) will cause electromagnetic fields when passing current. When the electrical con...

How to choose split core current transformer correctly?
Dec 17 , 2020
Current transformers can be divided into high voltage and low voltage, which are mainly distinguished by the highest voltage of the equipment. Generally, 10KV or more is high voltage, 10KV is medium voltage, and 1kv and below are low voltage. Split core current transformer is mainly used in low voltage, because SCT must be opened and closed, which makes SCT unable to carry out effective sealing an...
