Capacitors

Capacitors are devices capable of accumulating energy through the electric field. They are the basis of what we know today as batteries. The basic capacitor consists of two plates separated by a dielectric material or vacuum, so the conductive plates accumulate electrical energy that can be released during the discharge period. Electrolytic capacitors have polarised terminals and are therefore not suitable for alternating current (reverse polarisation destroys the oxide which short-circuits and burns the capacitor). Our offer includes both electrolytic and ceramic capacitors. The most important characteristics of capacitors are their capacitance measured in Farads, maximum voltage and maximum temperature in case of ceramic capacitors.

  • Ceramics

    Ceramic capacitors, also called capacitors, are used to collect energy. They consist of two conductive faces divided by the dielectric (insulator). The main parameters of ceramic capacitors, as in the case of electrolytic capacitors, are the capacitance, i.e. the capacity to collect charge and the voltage between the covers. Unlike electrolytic capacitors, these are non-polarised capacitors, i.e. it does not matter how they are turned on in a circuit. Ceramic capacitors have a strictly defined temperature coefficient and are characterised by low losses. These capacitors are used in high-frequency circuits, where they act as elements of resonant circuits, as well as in flitting and blocking.

  • Electrolytics

    Electrolytic capacitors are polarised, i.e. the direction of their inclusion in the circuit is important for them. These elements have properly described outputs, most often in the housing there is a foot which must be connected to the circuit ground (i.e. "minus" of the battery). The inside of such a capacitor consists of two covers, which are interwoven with dielectric (i.e. with paper soaked in electrolyte). The whole assembly is tightly wound and pressed into an aluminium cup, which is sealed with a rubber stopper. The covers are different: one is a metal electrode and the other an electrolyte. Therefore, it is important which one is connected to a higher potential (to the "plus") and which one to a lower potential (i.e. "minus").
