Reference designator E

[Aggressive_Doughnut]

As if the HP custom markings weren't annoying enough (salvaged parts from a printer), I have a board with a handful of parts that look like inductors or capacitors in 1210 size that are marked E - there's even a couple arrays of E parts in 0603 next to a C-marked capacitor array.  Has anyone seen these before and knows what they are?

E is normally some notation for Resistor.

Usually you see like 200E which means 200R

I've seen E used for resistance but I don't think that's it in this case. Attached is an image of a section of the board containing parts with reference designators R (resistor), C (capacitor), and E (no idea).  There are plenty of L (inductors) as well, but it's hard to get them all in one shot.  Sicne there are R, C, and L, designators, it seems like E is meant to be something else, even though it looks to me like an inductor or capacitor.  Also since this is the beginner forum, I'll link in the wiki for standard deisgnators for readers who might not have seen it yet.

Those are ferrite chip beads for EMI, considered different than an inductor in the circuit's overall picture. So I see them get a different reference designator, not "L"

This explains why I don't get sensical readings from RLC measurements...

Ah, sorry, it is clearer with that picture, they are EMI suppression ferrites.
