Thanks to the appearance of many single board platforms dedicated to amateurs and hobbyists, minicomputers have become popular among enthusiasts of robotics and electronics. Check out other models available in Botland.
THT ceramic capacitors - a Capacitor is a passive electronic component consists of a guide przedzielonego dielectric. The ceramic capacitor is much less sensitive to damage than the equally popular electrolytic capacitor. The store offers a wide selection of ceramic capacitors, from the smallest capacitance (PF 6,8) to larger (470 NF). All components are manufactured from ceramic, with a very good performance.
The ceramic capacitor is made in one or several plates of ceramic materials. Applied ceramics offers different properties depending on the chosen type of material. Relative permittivity - from a few to tens of thousands times greater than the permeability of the vacuum. Thus, the high values allow you to build small components whose capabilities can match the characteristics they are offering electrolytic capacitors. A very big advantage of ceramic capacitors is the lack of polarization is their biggest advantage over capacitors elektrolitycznymi.
The principle of operation and application of ceramic capacitors
The effect of the capacitor can be compared to the buffer, which stores energy within, and at the time of disconnection from the power source some time giving her away. The action is better able to illustrate an example in which the led is connected to the battery, and the capacitor is installed in parallel in front of the diode. At the time of the circuit, the led will light up (and the capacitor is charged). After disabling the led does not go off immediately, but only after a few seconds. The reason for the “release” of stored energy in a capacitor. Very often used with the coils you build filters to purify the signal or voltage stabilization. Ceramic capacitors work well in systems where the voltage can change very often. It is also ideal for use in digital electronics, which is based primarily on the use of microcontrollers. Ceramic capacitors are especially well at filtering high frequencies. Unfortunately, worse cope with the low frequencies and electrolytic capacitors operate exactly the opposite, so you should use them together, combining the advantages and eliminating the disadvantages. It is worth remembering that the price of ceramic capacitors is lower than the electrolytic - this information may be important when you buy large amounts (e.g., mass production).
