Current supply This type of circuit is often used to obtain non-isolated, low-current power at low cost. Its output voltage can usually be in the range of several volts to three tens of volts, depending on the Zener regulator used. The amount of current that can be supplied is proportional to the cu

Before editing, the article published in the Y capacitor voltage specifications has been eager to answer many readers, including one of the users asked "JY561K2FY5P" What does it mean? In fact, a series of numbers for the person who started to contact the capacitor is a code or other complex The thi

At present, there are tens of thousands of manufacturers engaged in the capacitance industry in China, forming a huge industrial system covering all the provincial capital cities, two cities and the county market. However, in such a prosperous and competitive market environment, there will be strong

Low level failure Mechanism of High Frequency Precision Capacitors. Mica is an ideal dielectric material for capacitors with high insulation, high temperature resistance, low dielectric loss and thickness of up to 25 microns. The main advantages of mica capacitor are low loss, good frequency stabili

Breakdown Mechanism of Ceramic Capacitor under High humidity. The breakdown failure of semi-sealed ceramic capacitors under high humidity is a common and serious problem. The breakdown can be divided into dielectric breakdown and surface arc breakdown. The dielectric breakdown can be divided into ea

Effect of moisture on deterioration of Electrical parameters. When the humidity in the air is too high, the water film is condensed on the surface of the capacitor shell, which can reduce the surface insulation resistance of the capacitor. Here, for a semi-sealed structure capacitor, moisture can al

Capacitance

Y2 capacitors: the foot distance is usually 7.5 mm; used to protect the earth from FG wire by crossing one side pair; rated voltage is 300VAC voltage up to 1800-2600VAC; it is basic insulation or additional insulation; not only that, the use of the two is also different. Y1 capacitor and Y2 capacito
