Nowadays resistors vary depending on their resistive element. For instance, it is possible to find a resistive element that is manufactured from bulk material. Wirewound ones, metal-strip, carbon composition and foil ones have this specific element. There is also a so-called film resistive element that is associated with the majority of modern types. Understanding the main advantages of film type resistors is very important for everyone who wants to make the right choice.
Modern ones may also vary. Among those one can find metal/metal oxide and carbon types. Of course, their technical characteristics are not the same and should be considered.
There are numerous reasons to make metal products your perfect choice. Their great stability is definitely one of them. The point is that high stability is required in a great variety of applications.
It should be also mentioned that metal ones can offer lower temperature coefficient in comparison to other types of resistor. Besides that, the tolerance is only about one percent. Another plus of these is that they provide a bit lower level of noise.
The best thing about carbon types is that they can withstand not only high voltages but also high temperatures. Many electronics constructors choose this type of resistor, because it can offer a wide resistance range. Besides that, it helps to avoid problems with outgassing.
When choosing any type of resistor, it is important to pay attention to electrical noise. It can be of two types: thermal noise and shot noise. The main thing to consider here is that thermal noise is fundamental to resistance. A good piece of news is that carbon ones have less of thermal noise.
It should be also noted that there are thin and thick film kinds. The important difference between them is a level of noise. The matter is that thick ones offer a much greater noise level than thin ones. This noise level is 10-100 times greater. Among the advantages of a thick resistor is the widest range of values. Besides that, they are much cheaper than the thin products. If to point out the benefits of using thin film resistor, high stability and a possibility of miniaturization should be mentioned.
You should consider not only advantages of film type resistors but also their disadvantages. It should be pointed out that all types of resistor have some disadvantages. It can help you decided upon the best one to use.
