We know that metal film capacitor
s, as a capacitor, are often changed by environmental factors, so we must always pay attention to its characteristics and pay attention to it when using it, so as to maximize its service life. Usually in the state of natural placement, if the humidity in the air is too high, a small amount of water vapor will permeate into it, so that the capacity of the capacitor will change. Therefore, it is better to place the capacitor in a relatively dry environment as much as possible. In addition to dryness, try to keep the environment clean to avoid excessive dust and acidic material loss. In addition to this, the metal film capacitors should be protected from additional voltages and environments where the ambient temperature changes too quickly. In many cases, It may not exceed the rated voltage, but the high-speed changing environment will always damage the quality of the capacitor. If smoke is found in the metal film capacitor during use, the power supply must be isolated to avoid fire. When you first use it, you must read the manual carefully, and master its work nature and characteristics so that you can accurately determine the location of the problem once you encounter a problem in the process of use. Metal film capacitors may have noise when they are in use. The main reason for the noise is that the effect of alternating current causes mechanical vibration between the films, and the voltage is not stable enough. Noise and high-frequency vibration, although this is the case, the noise does not actually affect the use of the capacitor, because the electrical characteristics of the capacitor itself have not changed in any way.
Wow, this sounds like a bit of a cruel question, but it is a vitally important question to ask yourself if you are struggling with your electrolytic capacitor suppliers and you would like to stop the electrolytic capacitor problem.
