Solve the problem of inductor heating

No matter what type of rod-shaped inductor coil, it is inevitable that it will heat up during use! Heating is a normal phenomenon, but if the heating is too large, it may not be a normal phenomenon.

In fact, the solution to inductor heating is essentially the same even for different inductor types. It needs to be solemnly explained: the function of the rod-shaped inductor coil is to store energy, suppress electromagnetic interference, pass DC and block AC. When the current flowing through the inductor coil is large, the coil will heat up. In severe cases, it will get hot, the inductance of the inductor will decay, and the surface temperature of the inductor body will rise. When the temperature rise current exceeds 40 degrees Celsius, the inductor will lose its inductance characteristics. In severe cases, the entire PCB board will be burned. According to the experience summary of the case, the common reasons for the heating of the rod-shaped inductor coil are mainly the following:

1. If the abnormal heating of the magnetic rod coil inductor is caused by improper use of the equipment, this only needs to adjust the use method and use it correctly according to the specifications. In fact, it can be solved.

2. If the abnormal heating is caused by the quality problem of the magnetic rod coil inductor:

The treatment method for this reason is relatively responsible, because it may involve the traceability of the magnetic rod coil inductor product itself. Any product quality problem means that there may be a large number of substandard products in the batch of magnetic bar coil inductors produced by the supplier.

The correct way to deal with it is to determine which aspect of the product causes the quality problem. Is it the poor quality of the enameled wire used, or the coil winding does not meet the requirements, or the problem with the core powder formula that causes abnormal heating? This requires our technical intervention and a comprehensive test and analysis of the product to find out the problem. As long as we can determine the problem, we can provide specific and effective solutions.
