Identification capacitor

Hello everybody, I searched the web without success, maybe someone in this forum can Help me. I would like to know:

brand/manufacturer

type of capacitor

what ist the meaning of "MIE”

I know M ist normally for the tolerance but IE is new for me.

Thanks for any help!

It should be a 0.47uF capacitor but not sure about the voltage.

Thank you Karl, I can’t even say if it is an ceramic capacitor or polyester or…? It was used in an Spectral amplifier (DMA180 S1), so late 80s I guess…

Unfortunately I cannot say for sure.
