The shelf life of SMD inductors is almost known to the insiders, which is generally about 6 months to 1 year, but it is not absolute. It depends on the manufacturing process and preservation environment of inductors. The life of SMD inductors made of inferior materials and placed in humid environment will be much shorter.
The factors affecting the life of the inductor are as follows
1. The factors affecting the life of the inductor of the patch are related to its material characteristics. Magnetic materials, such as ferrite materials, are fired at a high temperature above 1000 degrees, which have high strength and can be stored permanently. Some materials are greatly affected by temperature, and it is especially easy to lose the inductance of the patch when stored;
Second, the service life of SMD inductor is also related to enameled wire. When choosing the chip inductor, the inductor winding is carried out according to the inductance and resistance value, and the appropriate coating wire is used, so that the chip inductor in the circuit works simply, does not bear the load and has a long life;
Third, the environment is the biggest factor affecting the service life of the SMD inductor. Environment has a great influence on the life of inductor. If the inductor is not used as required, or if it is used as required, its service life will be shortened, otherwise it will increase the service time when used under reasonable requirements;
