Organic film capacitor use organic plastic film as the medium, and metal foil or metalized film as the electrode. They are made by winding (except for laminated structure). Among them, polyester film and polypropylene film are the most widely used. There are more than a dozen kinds of organic films used in the manufacture of capacitors. [...]
Reuters reported that, boosted by strong external demand, China's manufacturing recovered rapidly and the momentum exceeded expectations. Related factories are eager to fill the labor gap to complete export orders. Singapore’s "Lianhe Zaobao" stated that China’s exports have surged and the supply of containers has exceeded demand. China's latest export container shipping index hit a record high, [...]
Reasons that affect the capacity of film capacitors: The capacity of the film capacitor depends on the area of the film metal layer, so the decrease in capacity is mainly caused by the reduction of the area of the metal plating layer affected by external factors. In the capacitor manufacturing process, there is a trace of [...]
"The infectivity of new mutant strains has increased sharply" and "Britain upgrades epidemic prevention and control"... Since the outbreak of the new crown epidemic, the evolution of the virus has always been the focus of attention, and the latest mutated new coronavirus virus reported in the UK has caused public concern. Due to the recent emergence [...]
How to discharge an electrolytic capacitor 1. For small lead aluminum electrolytic capacitors, just short-circuit and discharge them directly, but generally we don't recommend them. 2. For the horn-type electrolytic capacitor with a little larger capacity, you can make a 220v/60-100w bulb, or use a resistor to discharge slowly. 3. For bolt-type high-voltage and large-capacity electrolytic [...]
