Nan pratik, filtè a ranplase CAPACITOR a 39pF, ak tèminal la tè santral la nan filtè a konekte sou tè a tablo PC. Se pou rezon sa gen yon twou ant 39pF mennen yo CAPACITOR. 39pF ak 3.3pF kondansateur yo ak 68nH ak 680nH endukteur yo ap Lè sa a, pa obligatwa, pandan ke se enduktansdèstokaj a 68nH ranplase ak yon lyen fil.

In practice, the filter replaces the 39pF capacitor, with the central earth terminal of the filter connecting to the PC board earth. That is why there is a hole between the 39pF capacitor leads. The 39pF and 3.3pF capacitors and the 68nH and 680nH inductors are then not required, while the 68nH inductor is replaced with a wire link.
