NPO capacitors are suitable for slot capacitors in oscillators and resonators, as well as coupling capacitors in high-frequency circuits.
Two X7R capacitors
X7R capacitors are known as temperature stable ceramic capacitors. When the temperature is between -55 ℃ and+125 ℃, the capacity change of the capacitor is 15%. It should be noted that the capacity change of the capacitor is nonlinear at this time. diode
The capacity of X7R capacitors varies under different voltage and frequency conditions, and it also changes over time, with a variation of approximately 1% Δ C every 10 years, resulting in a variation of approximately 5% over 10 years.diode
X7R capacitors are mainly used in industrial applications with low requirements, and their capacity changes under acceptable conditions when the voltage changes. Its main feature is that it can achieve a relatively large electrical capacity within the same volume. The following table provides the available capacity range for X7R capacitors.

Three Z5U capacitors
The Z5U capacitor is called a "universal" ceramic single-chip capacitor. The first thing to consider here is the temperature range of use. For Z5U capacitors, the main factors are their small size and low cost. For the three types of ceramic monolithic capacitors mentioned above, Z5U capacitors have the highest capacitance at the same volume. But its capacitance is greatly affected by the environment and working conditions, and its aging rate can decrease by up to 5% every 10 years.diode
