Default Help identifying resistor

Here is resistor that I need help identifying. The silver middle band is what is different. I can't find any charts with silver as a 3rd band on a 5 band resistor. It is R1 in a PS4 power supply ADP-200er is power supply-I think it was made by delta.

This looks like a coil to me,
What is the marking on the pcb ?
Just now i see....R1
0.16R?(current sensor)
is this connected to emitter of power transistor?

Yes it is. Has a fuse in series with it which obviously didn't do it's job.

I can't see any fuse..
Is this resistor open?
If you say about FB this is a ferrite bead.

Some resistors also mark the temp. coefficient. So I would read br 1, bl 6, silv-x0,01, gold tol. +/-5% , red temp. coeff. +/- 50 ppm/K. It makes sense, but Im not sure.

"If you say about FB this is a ferrite bead" yes this was what I was referring to. It measured very low so I assumed circuit protect fuse.

Went to a TV shop & owner matched colors to one on a TV board with only exception being last color band which probably temp like you said. It was .16 ohms. Thanks for all replys.

As has been said, bands are
1-brown=digit is 1
2-blue=digit is 6
3-silver=multiplier is 0.01
4-gold=tolerance is 5%
5-red= temp coefficient is 50 ppm/C

And it looks like a fusible resistor to me, with the chalky grey coating.

All mouser had was .15ohms. Would that be close enough?

That depends what it's purpose was.

If the resistor is supposed to be a current shunt then you need the .16 ohm.

If the resistor is there to for another purpose like help lowering surge current slightly, then you could change it's value slightly.

I think you should try to trace out the circuit enough to get an idea what it is there for.
