Answers to questions about the shelf life of chip inductors and influencing factors
Almost everyone in the industry knows the shelf life of chip inductors, usually about 1 year, but this is not absolute. It depends on the production process and storage environment of the inductor, and the chips produced with inferior materials and placed in a humid environment The life of the in...Read more -
Common mode inductance acts on the input end of the power module
A common mode inductor means that two coils are wound on the same iron core, with opposite windings, the number of turns and the same phase. Commonly used in switching power supplies to filter common-mode electromagnetic interference signals, EMI filters are used to suppress electromagnetic waves...Read more -
Analysis of factors that need to be paid attention to when selecting chip inductors
When we are choosing a product, we usually choose according to external factors. The same is true for chip inductors. We need to consider some external or internal factors to choose a suitable chip inductor for us, which affects the chip. There are many factors for inductance If the product needs...Read more -
How to distinguish shielded inductor and unshielded inductor?
I believe many people are confused about the comparison of shielded inductor and unshielded inductor. According to the difference of magnetic shielding performance, there are two different names of shielded inductor and unshielded inductor. Shielded inductor includes chip inductor and I-shaped in...Read more -
The function of chip inductors
1. Chip inductors are magnetic induction components with insulated wires, which are one of the commonly used passive components. 2. The function of the chip inductor: The function of DC resistance and AC is mainly to isolate AC signals, and at the same time form a resonant circuit with fil...Read more -
The difference between manganese-zinc and nickel-zinc of ferrite ring inductors
Ferrite magnetic ring inductance is divided into manganese-zinc ferrite ring and nickel-zinc ferrite ring. Depending on the material used, the calcined material is also different. The nickel-zinc ferrite magnetic ring is mainly made of iron, nickel, and zinc oxides or salts, and is made by electr...Read more -
The role of magnetic ring inductance
The magnetic ring of the magnetic ring inductor manufacturer and the connecting cable form an inductor (the wire in the cable is wound on the magnetic ring as an inductance coil). It is a commonly used anti-interference component in electronic circuits and is good for high-frequency noise. The sh...Read more -
The ferrite rob will have different impedance characteristics at different frequencies
Magnetic rob have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies, and the impedance rises sharply at high frequencies. The higher the signal frequency, the easier it is for the magnetic field to radiate out. Generally, signa...Read more -

How to select the inductor? This articlet tell you all!
Summary Inductors are very important components in switching converters, such as energy storage and power filters. There are many types of inductors, such as for different applications (from low frequency to high frequency), or different core materials that affect the characteristics of the induc...Read more -
What are the advantages of Sendust magnetic ring in inductance application?
Relative to the magnetic saturation flux density, ferrosilicon is higher than sendust. However, sendust has more prominent advantages, which are manifested in better soft saturation, negligible core loss, temperature stability and low cost of use. Inductors using sendust magnetic powder cores can...Read more -
What’s the role common mode choke play in daily life?
Today we are going to show you the role of common mode inductance of magnetic ring. The magnetic ring common mode inductance is mainly used for the following three points: 1. Magnetic ring common mode inductors are widely used in refrigerators, washing machines, cameras, small-size fluorescent la...Read more
