A tantalum capacitor is produced by AVX company, its market share is about 65%, it is precisely because of its in tantalum capacitor industry in a dominant position, resulting in AVX counterfeit products, counterfeit brand AVX tantalum capacitor, which is caused by the consequences of the introduction of AVX as can be imagined, the tantalum capacitor really how to fake identify:
1, welding pin, original AVX tantalum capacitor welding pin cathode is not the same as the negative, the positive electrode for the U model, which is concave into the, rather than with the negative is flat;
2, can go to tear off the AVX tantalum capacitor label, genuine original, can be easily torn off label, absolutely no problem (I don't know how much tear in the company, absolutely not bad), fake generally label themselves up, the paper is general, so put the basic tear down. It is easy to tear tear;
3, AVX tantalum capacitor can be opened to see the inside of the tape, with the above about each interval 25CM has a AVX of the words, fake tape generally did not play AVX.
Genuine: smooth surface, edges and corners, light red color uniform color uniform;
Fake: matte surface, laser marking, font has fine lines, there is a sense of burning, the edge will be incomplete;
On the light to see the surface is reflective;
Counterfeit: matte, with micrometer thickness than genuine thin 0.1mm;
Why to fake, it is very simple, 1 yuan a capacitor, after grinding nominal tantalum poly, 5 times the value of!
