Axial film capacitor
s are also called audio capacitors, through-core capacitors. Axial film capacitors using polyester film can be used in filter circuits, so what role do axial film capacitors play in filter circuits? Let's first understand what a filter circuit is. The so-called filtering is simply the operation of filtering specific band frequencies in the signal, which is an effective means to suppress and prevent interference. A circuit that allows signals in a certain frequency range to pass through normally and losslessly, and prevents signals in another frequency range from passing through is called a filter circuit. Use this kind of filter circuit to extract useful signals. This kind of circuit was first used in the communication field. The reason why axial film capacitors can be used in this circuit is that the axial film capacitors in the filter circuit can eliminate the pulsation in the voltage, that is, it can absorb the peak of the voltage and eliminate the valley of the voltage, which is the so-called passing a certain frequency range Signal while blocking a certain frequency range signal.

When the axial film capacitor is used in the filter circuit, we should pay attention to how much the ripple frequency in the filter circuit is, how much mA is the ripple current, how much is the DC voltage, and how much is the AC voltage to ensure the selection Appropriate axial film capacitors are used in the filter circuit.
