Identification method of true and false AVX tantalum capacitors

1. Welding feet. The welding feet of original AVX tantalum capacitor have positive pole and negative pole different.

2, you can go to tore AVX tantalum capacitor, home furnishings, and can be easily pulled off, label there is absolutely no problem, I don't know how to tear a in company, absolutely not bad), fake labels themselves up commonly, use paper is general, basic not to tear down, so the poster to tear up easily torn;

3. The goods of AVX tantalum capacitors can be disassembled to see the braiding inside. The word "AVX" is printed on the braiding belt at an interval of about 25CM.

Genuine: smooth surface, sharp edges and corners, uniform color of light red font;

Fake: frosted surface, laser marking, fonts with fine lines, burning feeling, even incomplete edges;

Genuine: the surface is reflective to light;

Counterfeit: frosted, micrometer thickness than the genuine 0.1mm;

Why to fabricate, very simple, 1 yuan a capacitor, after grinding the nominal tantalum poly, value-added 5 times!
