The appearance of the capacitor is generally not seen. The capacitor meter is measured to know. 1000000pf \\u003d 1000NF \\u003d 1UF, and the patch capacitance depends on the volume, that is, the size of the material, generally 0201, 0402, 0603, 0805, 1206.  
 
Many patch capacitors cannot be marked with their capacity due to the volume, so it is generally marked on the entire market during the production of the patch. If it is a single patch capacitor, use a capacitor tester to measure its capacity.  
 
If it is the same factory standard, in general, the color of the color is lighter than the color, and the brown gray\\u003e light purple\\u003e gray. Of course, the best way is to blow it off with a hot air gun. After cooling it, use the capacitor gear or capacitor meter with a digital table.
