Contact UsWhat do "in-line" capacitors do?
The capacitor charges up to the difference between the DC value of the signal source and the DC value of the signal destination. For example, if an audio signal is centered about ground at its source, but the destination circuit has only a single power supply voltage so its input sits at its Vcc/2, maybe 6 Vdc for a 12 V circuit, then the capacitor will charge up to 6 V …
