Weird resistor color code
Hello there!
In one SMPS, I noticed a blown resistor with the following color code:
yellow (4)
Violet(7)
Gold(?)
Gold
Black.
I'm not sure what the value is.
The dimensions of the resistor are those of a conventional MF0207 metal film resistor.
I assume it's a fusible resistor in series with the ferrite transformer's primary, with a TinySwitch TNY268 on the opposite side.
What is the value of the primary resistor?
