Hi forum.
Could You please tell me what kind of component is this?
A color coded capacitor? an inductor?
If I assume it is a capacitor it has color code 22pF +10% but the schematic does not help. It is placed at the positive input of an external DC 10V supply, so it should have no sense.... the 0V DC and the +10V DC are connected in the differential input of an opamp, and with the capacitor in series current can't flow...
If it is an inductor of 47uH it is in another place it shorts Vcc to ground...so I assume it could be a capacitor..but as above it has no sense.. Please help.
Any help really appreciated. Thank You very much.
sorry. upload did not work
The only thing that makes obvious sense to connect between Vcc and Gnd is a capacitor.
Are you sure your color-code reading is correct (possibly overheated color bars)?
That package is strange: looks like an old-school NP0 leaded part that makes little sense across Vcc.
The only thing that makes obvious sense to connect between Vcc and Gnd is a capacitor.
what about a bleeding resistor?
Thanks for the reply. The fact is that even an LCR tester does not recognize anything, except once it said a resistor with 89 ohm...
By the way. could a so small capacitor be destroyed by heating it up during normal desoldering process? the fact is that it is shorted for the tester... like a resistor as I said before..
Thank You
Thanks for your post.
Shouldn't be a bleeding resistor be a high value one?
and if yes, why not use same 1206 package as the one used nearby the opamp?
Now I would like to guess why use it to short Vcc to ground....
Are you sure thats what is shorting Vcc to ground? Maybe something else is shorted (Between the MELF and Vcc or between Vcc and gnd) and making it look like that when using an ohmmeter.
ie: How have you determined that one end of the MELF is supposed to be connected directly to Vcc?
