Hi guys if i have a SM resistor that should measures 100K and only measures 4K inm circuit on a power supply, what would be the symptoms?
You just said that, the symptoms are that you are measuring 4K instead of 100K. The reason most likely is that there are other elements in the circuit which means you are not mesuring only the resistor but a whole bunch of other components as well. Try taking it out of the circuit and measuring again.
Ah! SM in this context means Surface Mount, not SMall... I've never seen them referred to as SM; only SMT and SMD...
Obviously lifting one end is not possible...
What is the code on the resistor?
There are several types of codes used:
Thanks; it's a SMT code 104
As everyone else mentioned - other components will conspire to give a low resistance reading in circuit.Hi guys if i have a SM resistor that should measures 100K and only measures 4K inm circuit on a power supply, what would be the symptoms?
If they are truly in parallel, then you should be getting the same measurement for both. Why? Because they are in parallel!thanks but if i take it out and it measures only 4K instead of 100K ?also i have another same 100k in parallel and it gets the right resistance which is about 100K

So it's pretty clear that they are NOT in parallel. What makes you think they are?
