Siemens handsfree scheme

[asetyadi]

Dear all,

If we look at the "Siemens cell phones handsfree / headset / headphones scheme pinout" section, we found 3 pictures/scheme there.
In schemes A and B from pin 11 and 12 are connected to the mic (- and +) but before that there are two components that I am not sure what they are.
I ASSUME that the first component that connect pin 11 and 12 is CAPACITOR (C) and the second component in the pin 12 is INDUCTOR .
Please somebody correct me if I am wrong about that assumption AND also give me the value of those components.

Your reply is very much appreciated.

Thx n rgds,
Albert
