The service life of Flat Wire Common Mode Filter Inductor is affected by many factors, so it is difficult to give an exact fixed time, but a rough estimate can be made by analyzing its influencing factors.
First, the working environment of the inductor is a key factor. If it is in an environment with high temperature, high humidity or a lot of corrosive substances, its service life may be significantly shortened. High temperature will cause the performance of the materials inside the inductor to deteriorate. For example, the insulation layer of the coil may age and become brittle, thereby increasing the risk of short circuit. High humidity environment may cause the inductor to rust, affecting its electrical performance. In extremely harsh environments, it may fail after a few years of use.
Secondly, the current size and frequency passing through the inductor will also affect its life. Excessive current will cause the inductor to heat up more, and long-term high current state will accelerate the fatigue and aging of the internal materials. High-frequency operation will make the electromagnetic field inside the inductor change more violently, which may cause increased core loss and coil heating, thereby shortening the service life. If the operating current and frequency are within the normal range and the environmental conditions are good, its service life may reach 5 years or even longer.
The manufacturing quality and material selection of the inductor are equally important. High-quality core materials, good insulation materials, and sophisticated manufacturing processes all help to extend the service life of the inductor. Flat Wire Common Mode Filter Inductors made with high-quality materials and advanced processes can usually work stably for more than 5 years under normal use conditions.
In addition, the load characteristics of the inductor will also affect its life. If the load changes frequently or there are large instantaneous pulses, it will cause greater stress on the inductor, thus affecting its service life.
For example, in an industrial automation control system, the Flat Wire Common Mode Filter Inductor used has a service life of 8 years after reasonable maintenance and care due to the moderate working environment temperature, stable current, and small load changes.
However, in another communication device, due to the high operating frequency, large current changes, and harsh environment, the same model of inductor may experience performance degradation or failure after 3 years.
In summary, the service life of Flat Wire Common Mode Filter Inductors is usually between 3 and 8 years, but the specific duration depends on many factors such as the working environment, current frequency, manufacturing quality, and load characteristics. In order to extend its service life, it should be ensured to work in a suitable environment as much as possible, avoid overload and frequent drastic changes, and choose products with reliable quality.
