Capacitor marking

This appears to be a non-standard marking. Where did you find this? What is is out of? The 84 may be related to the cap value. Have you tried to measure it? I'm not sure about the "EG" part of it. This marking may be mfg specific, but the stand

Does anybody have the marking code for for a capacitor this one has "EG84" marked on it. I am getting a bit of list mainly for resistors, most capacitors are blank that we get. But dont have a "letter-letter-number-number" code

0603 marking

One of our board fab houses is asking (again) to eliminate the reference designators and polarity markings from boards. This isn't feasible for thru-hole, but what is the industry trend on surface mount assemblies?

HO what a BIG twit I am, for wasting your time (and a few hours myself trying many options on google). It is not EG84 it must be E684, (I will have another look next time I go back to work) you see I know the value, I thought it was a new secret co

Hello! I need some help! Does anyone know marking pen that is water soluble? I want to wash off marker in a cleaning machine using only hot water. I tried many different type of water soluble marking pen, but it did not come off easily.
