Need info about one obsolete Murata filter

[gaetan8888]

Hello

Anybody would have the specs or informations about this obsolete Murata filter, I did not found anything with Google.

It's a Murata filter, it's in a metal can and there is those writing:

Sony
273-21
Murata
R5N

There is 8 pins, 3 pins are not marked, one pin are the input, and there is those other pins: -12volt, out, gnd, +12volt, look at the image I've attached.

It's the output filter in a Sony CDP-70 cd player, one filter for each channel, there is no oversampling in this cd player.

Thank you

Bye
