Product Description

RC with resistor and capacitor

What is an RC capacitor? An RC capacitor refers to a capacitor that is charged by a power supply voltage V through a resistor R. It is also known as an RC filter, which is constructed from a resistor and a capacitor. RC filters can be classified as low-pass or high-pass filters, and the formula for calculating the cutoff frequency of an RC filter is: F(cutoff) = 1 / (2πRC). The cutoff frequency is the frequency at which the filter’s frequency response exhibits a turning point. This type of capacitor is manufactured by winding polypropylene film as the raw material and performing upstream processes, followed by gold-plating on both sides of the capacitor; it is then assembled with resistors of various resistance values to form either a series or parallel configuration.
