content: I've had these in my collection for a while now, and no idea what they are. They measure out at just under 4M?***Edit*** 4M-OHMS... Why doesn't this site display the ohm symbol? Of all the sites I've used the micro symbol (µ) and the ohm symbol (?), this is the only one that doesn't display them properly...I would have thought the nature of this site would have surely made sure these symbols didn't turn into question marks. They work everywhere else on the web, even Facebook!

content: Using the ALT code but doesn't work for me either it might have something to do with my system regional settings or how the browser interprets whatever character set is in use.Maybe Dave or one of the admins can confirm what encoding this forum is using then we might be able to get to the bottom of it. It appears to be using UTF-8.

content: It is an old bug, known for years. Somewhere the character encoding between what is used by the web pages (front end), and how SMF stores the data (back end) does not match.

content: It's just alt+Z for the Ohm symbol, and alt+M for micro symbol µ on mac. No fancy codes. It shows in the text box, but when you press 'Post' it turns into a ?...Anyway, back on topic, does nobody know what these parts are?

content: At a wild guess they are uncoated 4M resistors, with the value stamped on them. Likely they were intended to be used either potted or in vacuum operation.
