Comparison and application of tantalum capacitors and electrolytic capacitors

Tantalum electrolytic capacitor is the specific name of tantalum capacitor. Because tantalum metal is the medium of tantalum capacitor, tantalum capacitor does not need to use electrolyte as common electrolytic capacitor does. The capacity of tantalum capacitor is small, because tantalum capacitor has almost no inductance. In addition, tantalum capacitors are well suited to work at high temperatures because there is no electrolyte inside them. Would use the tantalum capacitor, so what kind of products for household electrical appliances product shape is compared commonly big, circuit board of the space also is enough big, so many household appliances are selected using price cheaper electrolytic capacitor, and in some high technology content, or shape small electronic products, due to the limitation of space, not put electrolytic capacitor, then can use tantalum capacitor instead of electrolytic capacitor, this is because if the electrolytic capacitor and tantalum capacitor to contrast, their capacity under the condition of the same, the volume of the electrolytic capacitor will be a lot larger than tantalum capacitor, tantalum capacitor use fixed number of year is long, but also high temperature resistant. However, tantalum capacitors are relatively expensive, so they are generally used in high-end products.

SLR cameras, SLR cameras, for example, typically on the market selling price will be higher, it is not only because its material is more expensive, but also for SLR camera functionality is very high, generally is a professional photographer or hobby photography people will buy the products, many of the functions of ordinary digital cameras are can't rival with SLR cameras, SLR cameras has the advantage of a lens is can the exchange of different specifications, 2 it is through the camera view. And most SLR cameras are sold separately in body and lens sizes. Customers who buy SLR cameras can choose matching lenses according to their different needs and actual situations. SLR cameras are also very powerful in sensing, which digital cameras can not be compared. If the SLR camera cannot be used frequently for some reasons, in addition to carefully cleaning the lens, fuselage and other important parts, but also pay attention to the maintenance of other parts and accessories.
