High Pass Filter

This circuit will form a high pass filter, passing through high frequency signals through to output, while filtering low-frequency signals through the inductor. Since the formula for a high-pass RL filter is f= R/2πL, doing the math we get, f= R/2πL= 10KΩ/(2(3.14)(470mH))= 3,388 Hz, which is approximately 3.39KHz.

How to Calculate the Current Through a Capacitor

How to Calculate the Current Through a Capacitor. To calculate current going through a capacitor, the formula is: All you have to know to calculate the current is C, the capacitance of the capacitor which is in unit, Farads, and the derivative of the voltage across the capacitor.The product of the two yields the current going through the capacitor.

High-Stability Capacitors for High-Frequency Circuits

In terms of packaging, the MLCC (ceramic disc for through hole) has become far and away the package most associated with high-stability capacitors. The former is formed by a homogenous, powdered mixture of the majority para or ferroelectric material as well as any metals necessary to form the dielectric.
