What is this item found on a PCB?
upl8:
Found this attached to the PCB of a Tivo. It has small holes in the middle of the case and loose balls inside. It was face-down with only the white paper backing showing from above. The only identifier on it is W09.
Psi:
My guess is moisture absorber/ desiccate.
rstofer:
Maybe it provides weight.
ataradov:
Weight was my first guess, but TiVO is a set top box like thing. I doubt it needs any additional weight.
But if this was on the remote, for example, then it is probably a dummy weight to make it feel more balanced.
upl8:
It only weighs 1.5 grams. As ataradov said, the Tivo is like a set top box. It has a 3.5" hard disk in it, so no need for an extra 1.5 grams. The balls inside aren't attracted to a magnet, but they easily pick up a static charge.
