The different ceramic materials used for ceramic capacitors, paraelectric or ferroelectric ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies. But these mixtures hav…

Replacing Capacitors With Different Values Guide

When replacing a capacitor with a different capacitance value, it is important to take into account any other components connected to it that might be affected by the change in capacitance. For example, an increase in capacitance could cause an increase in output voltage from a power supply circuit, which could damage the device …
