This was salvaged from a dead "Bush" branded "walkman" style product a few years ago and has been rattling around in my parts bin ever since. The marking on the back simply says "M7." with no other markings at all. The white material seems to be plastic. The blue area looks very similar to the surface of a PCB and the "traces" are raised from the surface and can be detected by a fingernail scratching the surface.
My meter tells me there is less than 1 ohm between the middle and left pins but does not measure anything on the other pin combinations.
I wondered if it might be a fancy resistor or some sort or perhaps an exotic inductor. The part was upright and freestanding when installed in the product, but was near to the AM/FM radio receiver circuits. Could it be an antenna even?
