Not even being an electron-made, ordinary problems with home appliances sometimes have to be solved independently: for the sake of saving money, time or simply in the name of self-development and interest. Very often to reanimate a home computer, for example, or other digital technique, it is enough to simply replace the non-working capacitor. It would seem that there may be a problem here, but the person who is not knowledgeable in this kind of affairs will certainly have any questions: and how to determine the non-working capacitor, and by what parameters should be selected by replacement, what else should I know? And all these problems are completely able to solve even yet far from the world of electronics to the user.
How to choose a type of condenser
Condenters, as in the popular song, are different. But in the widest understanding of us with you can be divided into ceramic and electrolytic. First of all, it affects their capacity, the ability to accumulate electric current. But there are other fundamental differences.
The electrolytic capacitor, due to the presence within the electrolyte, which can dry over time, has a limited expiration date, another thing is ceramics. True, it is electrolytic capacitors that are used everywhere, since they are not limited to electric containers, unlike their fellow, whose capacitive indicators are very modest.
The main electrical parameters of the condenser
The most important parameter that interests us in any condenser is its container, measured in micropraids. However, so that the product serves us the right and long service, it is worth paying attention to a number of other electrical characteristics:
- the limit level of voltage is measured in volts (the main thing is that it is higher than the network. Here, as they say, no porridge oil). But it is important to remember: the greater the limit voltage at the same capacity - the more dimensions of the product;
- electrical Type: Permanent or Variable. Moreover, in the DC network it is very important to observe the polarity of the plus and minus, otherwise the small, but very unpleasant fireworks is inevitable.
How to choose a capacitor capacitor
Having understood with the electrical parameters of the condenser, it is also worth it for the purpose of acquiring it. In the widest understanding, the capacitor is necessary to accumulate electrical energy. The greater the container - the more electricity it can absorb.
Modern electronics is unthinkable without the work of capacitors, where they are used in the operation of microcircuits, sound equipment, for smoothing current pulses and other things. In the AC network, condensers are often used as filters compensating for harmful network interference.
If we are talking about a simple replacement of a swollen or non-working capacitor - the easiest way to simply rewrite its nominal characteristics on a piece of paper and buy a similar component in the nearest electronics store. True, you will also have to master the skills of soldering.
We select a condenser for a computer
Very often because of the non-working capacitor may not include a home computer. This can also include sudden artifacts and glitches, such as a delay in the mouse, reducing performance, blue screen of death. In this case, it is necessary to disassemble the PC housing and explore the condensers for blinking.
A selection of a computer for a computer should not make special problems, because its characteristics are clearly indicated on the body of the product. It is very important to observe the polarity when soldering, otherwise the capacitor at the first inclusion will simply burn. Send the skills of soldering, in fact, not so difficult. The main thing is to remember that small electronic components should not overheat through the measure, including condensers.
In such a way as to correctly select a capacitor, you only need to know a number of electrical parameters as its voltage, the type of current and the container. It is not so difficult to visually determine the non-working electrolytic capacitor for its bloating and damage to the case. To replace the non-working component on the electronic board, you will also have to master the skills of the soldering.
