please help identify a component
 

hi anyone,

i have a small electronic component that i can't identify. it looks like
a typical 1n4001 diode, similar size and shape with axial leads, but
there's no marking on it except for a single yellow stripe at the
midpoint.

i got a switch mode power supply and it has about a dozen of these
things in the circuit.

what are they?

thanx, louie

please help identify a component

it's near zero ohms, could be a small inductor.

that, it turns out, is what it is. ferrite inductor used to smooth out
the high frequency output of the transformer in a switching power
supply. thanx for the reply.
