Bill of Materials (Legacy TBR21 Current-Limit Support)
(All resistors are ±5% and capacitors ±20% tolerance unless indicated otherwise.)
Note 1: For optimal audio performance, C7 and C11 should have a 250V rating and be of 1206 size. This is especially important for
Note 2: C10 and C14 need to be NPO if V.90 modem performance is required. Otherwise, it is more cost effective to use X7R

applications where the PCB is less than the standard 0.062” thickness, because ceramic capacitors are slightly piezoelectric
and therefore sensitive to mechanical vibrations (microphonics). This effect is less pronounced with components of larger
size and higher voltage rating.
