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 inductor will be much shorter.
There are two factors that affect the life of chip inductors:
1. Factors affecting the service life of chip inductors are related to the material characteristics
Magnetic materials, such as ferrite, are fired at a high temperature of more than 1,000 degrees. They have high strength and can be stored forever. Some materials are greatly affected by temperature, and it is especially easy to cause chip inductance loss during storage。
2. The service life of chip inductors is also related to the enameled wire used
When selecting a chip inductor, the inductor will be wound according to the inductance and resistance value. By using a suitable enameled wire, the chip inductor in the circuit can work easily without carrying too much load, and the service life will be longer.‘
3. The biggest factor affecting the service life of chip inductors is the environment
The environment has a great influence on the service life of the inductor. For example, when the inductor is used in a poor-quality environment or is not used as required, its service life will be reduced. On the contrary, if it is used under reasonable requirements, it will increase the use time.
