Hi! I’m trying to find the tracks within a PCB. But I’ve got no idea what are these components. Does anybody know what are they? Enviado desde mi iPhone utilizando Tapatalk |

Potentiometer. |

Trim pots to be more precise. They are adjusted by a small flat blade screwdriver via the slot in the middle. From the numbers on them, the resistance of each are: 103 = 10K ohm 202 = 2K ohm 503 = 50K ohm Edit: They are placed in circuits that need to be adjusted when they are first built and tested. Once adjusted, they should not need any further tweaking in normal service. Translation: Don't fiddle with them unless you know what you are doing and why. |

Like Brumby says. But in addition The first 2 numbers times the multiplier. 0 = 1 , 1=10 ,2=100,3=1000,4=10000 ,5 =100000. So the top left is 10 times 1000 or 10000 ohms or 10K Ohms.The top right is 20 X 100 or 2KOhms and so on |
