Application and Development Trend of Thin Film Capacitors
Film capacitors are mainly used in electronics, home appliances, communications, electric power, electrified railway, hybrid electric vehicles, wind power generation, solar power generation and other industries. The stable development of these industries has promoted the growth of film capacitor market.
What should be considered in designing capacitive touch screen system
In a traditional resistive touch panel, when the finger or stylus is sensed, the top layer of flexible transparent material is pressed down to contact the conductive material layer below; Projective capacitance screens have no moving parts.
Three Compositions of Supercapacitors
There are three common types of supercapacitors: series, parallel and series-parallel. Supercapacitor assembly in series: Since the single working voltage of the supercapacitor is not high enough to cover the voltage requirement range of the application condition, multiple monomers need to be connected in series to meet the voltage requirement of the application condition. However, due to the inherent differences between the single capacitors, the total voltage acting on the series components cannot be evenly distributed to different capacitors, which will lead to the asymmetry of voltage distribution.
