To suppress noise in the headphone connection, it is important to
minimize the GND’s noise level. The PCB’s GND and metal
case are screwed together to form a low-impedance connection at high
frequency.
The NFM21C Series (Chip Solid "EMIFIL®") capacitor is
then installed on the headphone lines so that their GND connection
has low impedance. More effective noise suppression can be achieved
by installing BLM Series (Chip Ferrite Bead) on the lines. |
