Factory requirements of safety capacitors and its different forms
For safety capacitors, we may not be familiar with it or know it, but our life is inseparable from it. It often appears in small household appliances and power chargers. Today, I will briefly describe the safety capacitors. Factory condition and its different forms. The function of safety capacitors is just like its name. When encountering bad products or improper use, electric shock, fire and other accidents, it will reduce the harm, reduce the user's property loss, and protect the user's safety. It is often used in circuits. Bypass, energy conversion, coupling, blocking through traffic, filtering, control, etc. Safety capacitors play an important role in the electrical appliances we use.
The production of safety capacitors must comply with safety regulations and pass the safety standard test certification, because not every country's household electricity voltage is the same, generally after the safety capacitors are produced, the voltage will be tested in the relevant departments, so When we see a safety capacitor, its surface Run Capacitor will be printed with the safety certification LOGO of many countries. There are many types of safety capacitors. The most common and the most used are Y capacitors and X capacitors. Most of the X capacitors are square, that is, shaped like a box, and its capacity is uF level. The yellow X capacitor is the most common X capacitor on the market, and it is also the earliest capacitor on the market. The appearance of the yellow safety capacitor is eye-catching, and it is laser printed, with good printing effect and clear handwriting. Blue shell and red shell are the two capacitor colors commonly used by well-known foreign brands. While strictly controlling the product quality, its novel and bright shell color can better reflect its uniqueness.
Y capacitors are usually ceramic capacitors. In the past, they were mostly oblate and blue in color. The capacity of Y capacitors was nf level. Of course, with the advancement of the times and the advancement of science and technology, Y safety capacitors are not static. It has a new SMD Y capacitor. This SMD Y capacitor has the advantages of small weight, light weight and high reliability. , which are very suitable for gallium nitride and small household appliances products, and, with the explosion of gallium nitride chargers in the market last year, more and more chargers, power supplies, and small household appliances companies have begun to use this patch Y capacitance. The above is the editor's introduction to the role of safety capacitors and its different forms. We will see you in the next issue.
