Help Identifying a Component from a Power Conditioner Board

[jmurphy]

I was examining the guts of a power conditioner and came across a few components that I’m having trouble identifying. I've attached a photo of the components in question. It's an axial component, shaped quite like a diode, but it lacks any visible markings. There are several identical components and they all have labels that start with "BIT," and I'm curious about what this prefix might stand for.

They are ferrite beads for suppression of RF noise.

No idea what the "BIT" prefix stands for.

I found a Chinese company selling matching ferrite beads on eBay and the part number started with BIT.
Thanks!
