Resistor Value

autodeskguest

Hi,

I was analyzing the schematic attached and found the resistors R51 and R48

marked as "0R". What does that mean? Anybody understand this ?

    Hello Thiago

     

    It means zero ohms. As well 4R7 is 4.7 ohms, 1k2 is 1200 ohms and 6M8 is

    6800000 ohms.

  • generally these are fuses or ferrite bead.

    Sure image

     

    You have to mount only one of them. You can choose where you will get

    the power to. Maybe ...

     

    It would be better if you send us more informations. Now we can guess

    only image !

    I doubt that. I am 99% sure that this denotes a supply to both Vdd AND Vcc;

    a power distribution point. Means, 0R "bridges" in BOTH places. The reason

    may be that you can simply detach individual supplies, to facilitate

    debugging. These bridges can also be replaced by some low valued resistor in

    case there are noise problems.

    I would suggest that the designer has split power supplies. The rest of

    the circuit requires both Vcc and Vdd supplies. For one reason or

    another, these have not all been named as the same net. perhaps one is

    an analogue rail, the other digital. They are brought together where

    these resistors (jumpers really) are on the board. The same trick can be

    used to have split grounds.
