As with radio control helicopters resistors,Capacitors and radio control helicopters systems Articles from a few commercially available discrete values is possible to obtain virtually any capacitance value we want, simply combining of two or more. There are two basic ways to do so, in series and parallel. This will make your rc heli work well.

Capacitors in series

The group is to link series radio control helicopters capacitors one after the other, as shown in the diagram of FIG. Thus, the current I flowing through them is the same. In fact, no current (at least in the direction of flow of electric charge) flows through a capacitor. However, since the loads on the trusses are always equal and opposite, the current entering one terminal is always equal to that emerges on the other, so for practical purposes we assume a current flow through the condenser.

Because of the way they behave armor and you have loads to the capacitors in this way, the total capacity of the array is calculated using a formula. Different systems are used to write the value of the capacitance of the capacitors, depending on the type of question. In the case of electrolyte directly expresses the ability with numbers, usually in uF, so no problem reading. Accompanying this maximum stress value which has been designed, and not to be overcome if we do not want to end the life of the radio control helicopters components.

In the case of ceramic capacitors, using a system similar to the resistors, but instead of using color bands, the value is expressed with numbers. It is common to find written on the body of these capacitors a 3-digit number, where the first two correspond to the units and tens, and the third the number of zeros. The capacity is in farads, so it may be necessary to make the conversion if you want to know the value in another unit. Thus, if the number is written, for example, 474 means that the capacity of Ceramic Capacitors

Ceramic capacitors are manufactured with relatively small capacity between 1 pF and 470 nF (0.47uF). The tolerance varies. Physically, they resemble a lentil with the two terminals coming from one of the radio control helicopters edges. They are capable of withstanding voltages between 50V and 100V, depending on the model, although there are specially made to support up to 10,000 V. Their identification is performed by an alphanumeric code.

They are mainly used in radio control helicopters circuits that require high stability and low losses at high frequencies. The manufacturing process consists basically of two-sided metallization of the ceramic material, which makes their cost is very small.
