LIke it says, it's a ferrite bead with six holes - presumably you wind wire through it to make an RF choke.

Have you tried a google search, have just searched for a VK200 ferrite and got a few results including retailers with stock, Karl.

It increases the inductance of a few turns of wire. You do know what inductance is for. Right?
