Resistor with "1:R2" printed on it.....what value should I read?

[Francesc V.]

Has this two dots any meaning? Because there are several and I would say they measure about 11 ohms.........however, my common sense tells me that they should be 1.2 ohms........right?

It's a 1210 SMD resistor, just if it helps.

Regards,
Francesc.

I would think the same as you. I don't recall ever seeing that marking style, though. Can you show us the whole PCB? Maybe we could infer an appropriate value by determining the functions of the resistors in the circuit.

It belongs to a Schneider Solar Inverter

It seems to me that the resistor should carry a reasonably high current, so 11 ohms doesn't make sense.

[Francesc V.]

These two dots, with a little bit of imagination turns into an 8 (eight)...............so I guess that these resistors might be 18R2 :-)
It makes sense as long as some in the circuit measure 18.4

What do you think?? Do we accept an eight? xDD

googles take on it ..
The image shows two surface-mount resistors, both marked with "18R2", which indicates a resistance value of 18.2 ohms. These resistors are likely metal foil resistors, known for their precision and stability, and used in applications requiring accurate resistance values.
Foil resistors are constructed with a thin metal foil mounted on a ceramic substrate, offering excellent heat conductivity. The markings "18R2" denote a resistance of 18.2 ohms, with the "R" acting as a decimal point. These components are typically used in circuits where precise current control or voltage regulation is needed.

Try to determine how much current those resistors are required to carry in that circuit, then calculate the wattages to see if they make sense.

FWIW, D10 is a 1A 40V Schottky Diode (VS-10BQ040-M3/5BT):

Thank you all for the responses and your time.
