Unknown electret micro

[atferrari]

Yesterday I bought this electret micro. The guy at the counter did know nothing about it and couldn't supply any link to the datasheet.

In the invoice it is mentioned as EMC-30CTERM.

The small tab is connected to the metallic cover.

Can anyone help me with the datasheet or at least in identifying the pins?

Problem solved.

The tab and the pin next to it go to GND.

one pin is ground. It goes to the case. Of the other two, one is + supply., the other is output. 5 to 9 volts is good.
One way round it'll work, the other it wont. You wont hurt it by getting it wrong.
