How to extend the shelf life of chip inductors?
As for the shelf life of chip inductors, I believe everyone knows it, usually 6 months, depending on the manufacturing process and storage environment.
In terms of service life, we must first start with the characteristics of magnetic materials. Generally speaking, ferrite materials are cast at a high temperature of more than 1,000 degrees.
Therefore, it has high strength and can be guaranteed forever. Then it is enameled copper wire. Generally, when choosing an inductor, it will be based on the inductance.
DC resistance DCR and DC current IDC are evaluated. The current is usually halved. Of course, the smaller the resistance, the better.
If all parameters are met, the coil will work easily. When the inductor is installed on the PCB board, it can be guaranteed forever. Of course, if it works in harsh environments or is not used as required, its life will be reduced accordingly.
SMD inductors, chip inductors mainly have 4 types, namely wire-wound, multilayer, woven and thin-film chip inductors. Two types of wire-wound type and laminated type are commonly used.
has good magnetic barrier properties, high sintered density, and good mechanical strength. Integrated structure, high reliability; good heat resistance and solderability; regular shape, suitable for automatic appearance installation and production.
