What is this? (Motherboard compnent question)

[Thanatos]

I have a ton of these on my motherboard and they tend to get quite warm... what are they?

the numbers on it pull up a MSDS for low stray capacitance inductors. I have no idea what they are though.

Darn wikipedia, I still don't get it. thanks though!

seems from that article that it is a static charge that builds up in circuits because of the proximity of them to each other and that it is unavoidable.

Here's where I got the picture from... apparently his caught on fire!

just guessing, I am far from an electrician, but I would guess that his got overpowered, resulting in heat above the burn point for that component. Assuming what we have found is the right thing, then they are responsible for stopping crosstalk between the circuits. So if one were to get far more energy, say from a power surge from the PSU, then it could theoritically fail. possibly?

Again, I am no expert, so just guessing.

Your guess is as good as mine.
