Capacitance, also called capacitance, is the amount of charge stored at a given potential difference, recorded as C, in Farads (F). Generally speaking, the charge will be moved by the force in the electric field, and when there is a medium between conductors, it will prevent the charge from moving and make the charge accumulate on the conductor, forming the accumulated storage of charge, and the stored charge is called capacitance. Capacitance is one of the electronic components used in many electronic devices, so it is widely used in isolation, coupling, bypass, filtering, tuning circuit, conversion, control circuit, etc.
With the rapid development of science and technology products, people’s living standard has been improving, and many electronic products have entered the family, because these devices have the risk of electric shock, fire, harmful radiation, chemical, blasting and mechanical injury, in order to protect the life and property of users, protect the interests of customers, and promote the enterprises to improve the quality of production, the country has formulated the standards of the products to reduce the above risks to small, and through legislation to ensure The implementation of the standards is ensured through legislation. The national certification organizations recognized by the country, the electronic products that have passed the relevant tests, to be recognized, to confirm that these products meet the relevant standards. Safety-compliant capacitors
The difference between high-voltage porcelain chip capacitors and safety capacitors is not clear to many people when choosing safety capacitors. The main consideration is the insulation level. The high-voltage porcelain chip capacitor is the general capacitor, which may not require safety approval, so it cannot be used before rectification, and cannot be connected across the right insulation requirements… The next step is to talk about how to choose the parameters of the safety capacitor.

The quality of the capacitor parameters in the switching power supply is generally the larger the capacity, the better, assuming the removal of fixed frequency harmonics, available f = L/2π*C accounting. Capacitor is one of the many electronic components used in electronic equipment, widely used in isolation, coupling, bypass, filtering, tuning circuit, conversion, control circuit and so on. In fact, you can also learn from the CE certified switching power supply (the same power or close to it) after disassembling and measuring the filtering inductor parameters and the amperometric capacitor parameters. x2 amperometric capacitor
When choosing the safety-regulated capacitors, you must find the regular manufacturers. For example, production equipment; R&D strength; whether the safety certification is complete to ensure the quality of safety capacitors. When you find a regular manufacturer of safety capacitor, the type of safety capacitor is complete, the parameter information is complete, and the manufacturer can also assist reasonably.
