That starting is followed by one letter and 2 or more numbers. The letter which follows 2S markings tells what type of transistor it is: A = PNP small power general purpose B = PNP power C = NPN small power general purpose D = NPN power J = P-channel fet K = N-channel fet ---------------------------------------------------------------------------- Resistor color codes Color 1. 2. 3. 4. --------------------------------------------------- Black | 0 | 0 | - | Brown | 1 | 1 | 0 | Red | 2 | 2 | 00 | Orange | 3 | 3 | 000 | Yellow | 4 | 4 | 0 000 | Green | 5 | 5 | 00 000 | Blue | 6 | 6 | 000 000 | Magenta | 7 | 7 | | Gray | 8 | 8 | | White | 9 | 9 | | Gold | | | x 0.1 | 5 % Silver | | | x 0.01 | 10 % --------------------------------------------------- gold or silver colot bar to right start reading the colors form left to right. 5 color bars Color 1. 2. 3. 4. 5. --------------------------------------------------- Black | 0 | 0 | 0 | - | Brown | 1 | 1 | 1 | 0 | 1 % Red | 2 | 2 | 2 | 00 | 2 % Orange | 3 | 3 | 3 | 000 | Yellow | 4 | 4 | 4 | 0 000 | Green | 5 | 5 | 5 | 00 000 | Blue | 6 | 6 | 6 | 000 000 | Magenta | 7 | 7 | 7 | | Gray | 8 | 8 | 8 | | White | 9 | 9 | 9 | | Gold | | | | x 0.1 | Silver | | | | x 0.01 | --------------------------------------------------- put accuracy color bar (brown or red) to right start reading from left to right. Reading surface mount resistors Surface mount resistor have three numbers: first two digits being multiplied by third. third digit represents how many zeros surface mount resistor with code 1-0-5 mean 1Mohm. same coding used in surface mount capacitors. Capacitor base number is pF or pico farads. eg a capacitor labeled 2-2-3 has the value of 22 000pF. Bad Boys Ravage Our Young Girls, But Violet Gives Willingly.
