The number means that apr901v2 package measures 0. The resistor R5 and capacitor C5 connected across the pin 20 and pin 21 provides an additional cut-off to the low frequency end of the voice pass band. Note that the resistive element in an SMT resistor is exposed and colored, and it should face upward to dissipate heat.

The serial flash chip is a 3.


I think this circuit is enough for the purpose. The RCN series combines resistor and capacitor technology on a single chip to provide filtering capability together with excellent.
