Default Inductor or resistor

See attachment.

This blown component is connected to the output of a bridge rectifier on a SMPS.

It looks like a resistor (it has colored marking lines), but it is marked as L1 on the PCB, suggesting it is a coil. Which is it?

This is a very basic and cheap SMPS which I am analyzing for learning purposes.


PS: don’t worry, I know there are about 330V after that bridge rectifier IF powered and I take the necessary precautions.
