the biggest difference between solid-state electrolytic capacitors and ordinary capacitors, i.e. liquid aluminum electrolytic capacitors, is the use of different dielectric materials. the dielectric materials of liquid aluminum capacitors are electrolyte, while the dielectric materials of solid-state capacitors are conductive polymer materials. so what type of electrolytic capacitor to buy depends on the actual demand, let's understand the characteristics and application range of solid-state electrolytic capacitor and liquid electrolytic capacitor.
solid state electrolytic capacitor
appearance: the shell is made of aluminum metal with specifications printed on the top, most of which have no explosion-proof wire.
volume: relatively small
impedance: relatively small
dielectric materials: conductive polymer materials
price: high cost
working frequency: suitable for high frequency
temperature characteristics: high and low temperature stability
应用范围：断路器型电力计、mdl power logger电能记录仪、摄影机、led广告牌、计算机、高阶服务器、ipc、主板cpu外围、lcd tv、绘图卡、游戏机、电信路由器。
application scope: circuit breaker type power meter, mdl power logger, camera, led billboard, computer, high-level server, ipc, main board cpu peripheral, lcd tv, drawing card, game machine, telecommunication router.
liquid electrolytic capacitor
appearance: the aluminum shell is mostly covered with plastic film, with explosion-proof wire above, and explosion-proof slot with "k" or " " shape.
volume: relatively large
impedance: relatively large
dielectric material: electrolyte
price: low cost
working frequency: suitable for low frequency
temperature characteristics: low temperature electrolyte solidification; high temperature electrolyte expansion, high pressure burst
application scope: consumer electronics, industrial applications, information electronics, communication products, automotive and other fields.
if you want to buy electrolytic capacitors, you must choose according to the industry and product characteristics of the enterprise. shandong hongbao electronics, as a leader in the capacitor industry, has provided a long-term and stable source of capacitor goods for many well-known large enterprises, with high cost performance.
