Stick a technology to be changed to miniature as SMT, efficient change development, of all kinds and commonly used yuan of parts of an apparatus is smaller and smaller also. Stick a resistor commonly usedly, stick an inductance and stick a capacitance to also become on the appearance distinguish hard. How should distinguish quickly again so is commonly used SMT stuck piece yuan of parts of an apparatus? With respect to You Jingbang the technician of science and technology is the method that you introduce to distinguish quickly below. 1.

Stick an inductance and those who stick a capacitance is divisional: (1) see color (black) -- general black is to stick an inductance. Stick a capacitance to be brave in only accurate equipment sticks a tantalum capacitance mediumly just is black, other and common stick a capacitance basic not be black. (2) see model coding -- stick an inductance with L begin, stick a capacitance with C begin. From the appearance it is a circle preliminary judgement should be inductance, measure two upright resistor to be zero Europe, it is inductance. (3) detect -- stick an inductance average block value is little, do not have more " charge discharge " caused avometer index makes a round trip deflexion phenomenon. And stick a capacitance to have fill discharge phenomenon. (4) see internal composition -- it is OK to look for yuan of identical parts of an apparatus sliver yuan parts of an apparatus sees internal composition, those who have coil structure to stick an inductance. 2.

Stick an inductance and those who stick a resistor is divisional: (1) judge according to the appearance -- the appearance of inductance has polygonal state, and resistor is given priority to basically with the rectangle. Have polygon when appearance of yuan of parts of an apparatus with divisional need, especially when the circle, maintain commonly for inductance. (2) measure resistor numerical value -- the resistance of inductance is less, somes the resistance of resistor is relatively great. 3.

Stick a capacitance and those who stick a resistor is divisional: (1) see color -- stick a capacitance to be gray, green gray, yellow more, it is a bit more shallow than hard paper carapace yellow normally. Some sticks a capacitance to go up without lettering, basically be its are become through high temperature agglomeration, bring about cannot be in its surface lettering. (2) see a sign -- stick a capacitance to be in the symbol in circuit " C " , the symbol that sticks a resistor is " R " . (3) measure a way -- the block value that sticks a capacitance commonly is very great, and stick a resistor relatively lesser. Stick a capacitance to have fill discharge phenomenon, and stick a resistor. Should be familiar with only all sorts of yuan the function of parts of an apparatus and model, very can fast divisional yuan of parts of an apparatus of all sorts of appearance likeness.
