The safety capacitor is divided into x type and y type. AC power input is divided into 3 terminals: Fire L/Zero N/Ground, (L=Line, N=Neutral, G=Ground). Between “L-N”, i.e. “Fire-Zero”, is…
The X capacitor is also one of the safety capacitors, as the location of this capacitor is also critical. According to the actual needs, the capacitance of the X capacitor…
Y capacitors in safety capacitors: The two Y capacitors are connected in a critical position and must meet the relevant safety standards in order to prevent electronic devices from leakage…
With the rapid development of China’s economy, people’s living standards continue to improve, a large number of electronic products into the home, due to the existence of these devices electrocution,…
A film capacitor is a capacitor constructed by using a metal foil as the electrode and overlapping it with a plastic film such as polyethylene, polypropylene, polystyrene or polycarbonate from…
Film capacitor is a performance capacitor because it has many excellent characteristics. Its main characteristics are as follows: non-polarity, very high insulation impedance, excellent frequency characteristics (wide frequency response), and…
Film capacitors are made by overlapping a metal foil such as aluminum as the electrode and a plastic film and winding it together. However, there is another manufacturing method for…
Film capacitors are mainly used in many industries such as electronics, home appliances, communication, electric power, electrified railroad, hybrid cars, wind power generation, solar power generation, etc. The stable development…
Variable amperage capacitor is a capacitor whose electric capacity can be continuously adjusted within a certain range, and it is a kind of commonly used adjustable electronic components, including single-link…
1 Preface Electromagnetic interference in switching power supply modules has always been an important solution point. In principle, electromagnetic interference mainly comes from two aspects, which are conducted interference and…
