Chip capacitor classification
NPO capacitor
Two X7R capacitors
Three Z5U capacitors
Four Y5V capacitors
Differences: The main difference between NPO, X7R, Z5U, and Y5V is that they have different filling media. In the same volume, the capacity of the capacitor formed by different filling media is different, and the resulting dielectric loss, capacity stability, and the like of the capacitor are also different. Therefore, when using a capacitor, different capacitors should be used depending on the role of the capacitor in the circuit.
NPO capacitors

NPO is one of the most commonly used monolithic ceramic capacitors with temperature compensation. Its filling medium consists of lanthanum, cerium and some other rare oxides.
NPO capacitors are one of the most stable capacitors with dielectric and dielectric losses. The temperature change from -55°C to 125°C changes the capacity to 0±30ppm/°C, and the capacitance changes with frequency less than ±0.3°C. The drift or hysteresis of the NPO capacitor is less than ±0.05%, which is negligible with respect to the film capacitance greater than ±2%. Its typical capacity changes with the service life is less than ± 0.1%. NPO capacitors vary in capacitance and dielectric loss with frequency depending on the package type. Large package sizes have better frequency characteristics than small package sizes. The following table shows the range of capacities that can be selected for NPO capacitors.
Encapsulation DC=50V DC=100V
0805 0.5---1000pF 0.5---820pF
1206 0.5---1200pF 0.5---1800pF
1210 560---5600pF 560---2700pF
2225 1000pF---0.033μF 1000pF---0.018μF
NPO capacitors are suitable for oscillator, resonator tank capacitors, and coupling capacitors in high-frequency circuits.
X7R capacitor

The X7R capacitor is called a temperature-stabilized ceramic capacitor. When the temperature is between -55°C and 125°C, the capacity change is 15%. It should be noted that the capacity change of the capacitor is non-linear at this time.
The capacity of the X7R capacitor is different under different voltage and frequency conditions. It also changes with time, changes by 1% ΔC approximately every 10 years, showing a change of about 5% in 10 years.
The X7R capacitor is mainly used in less demanding industrial applications, and its capacity change is acceptable when the voltage changes. Its main feature is that the capacitance can be made larger under the same volume. The following table shows the range of capacities that the X7R capacitor can select.
Encapsulation DC=50V DC=100V
0805 330pF---0.056μF 330pF---0.012μF
1206 1000pF---0.15μF 1000pF---0.047μF
1210 1000pF---0.22μF 1000pF---0.1μF
2225 0.01μF---1μF 0.01μF---0.56μF
Z5U capacitor

Z5U capacitors are called "universal" ceramic monolithic capacitors. The first thing to consider here is the operating temperature range. The main thing for a Z5U capacitor is its small size and low cost. For the above three ceramic monolithic capacitors, the Z5U capacitor has the largest capacitance in the same volume. However, its electrical capacity is greatly affected by the environment and working conditions, and its aging rate can be reduced by up to 5% every 10 years.
Although its capacity is not stable, it has a wide range of applications due to its small size, low equivalent series inductance (ESL) and equivalent series resistance (ESR), and good frequency response. Especially in the application of decoupling circuits. The following table shows the range of values for the Z5U capacitor.
Encapsulation DC=25V DC=50V
0805 0.01μF---0.12μF 0.01μF---0.1μF
1206 0.01μF---0.33μF 0.01μF---0.27μF
1210 0.01μF---0.68μF 0.01μF---0.47μF
2225 0.01μF---1μF 0.01μF---1μF
The other technical specifications of Z5U capacitors are as follows:
Operating temperature range 10°C --- 85°C
Temperature characteristics 22% ---- -56%
Dielectric loss up to 4%
Y5V capacitor

The Y5V capacitor is a general-purpose capacitor with a certain temperature limit that can vary from 22% to -82% in capacity from -30°C to 85°C.
The high dielectric constant of Y5V allows up to 4.7 μF capacitors to be fabricated at smaller physical dimensions.
Y5V capacitor range as shown in the following table
Encapsulation DC=25V DC=50V
0805 0.01μF---0.39μF 0.01μF---0.1μF
1206 0.01μF---1μF 0.01μF---0.33μF
1210 0.1μF---1.5μF 0.01μF---0.47μF
2225 0.68μF---2.2μF 0.68μF---1.5μF
Other technical specifications of Y5V capacitors are as follows:
Operating Temperature Range -30°C --- 85°C
Temperature characteristics 22% ---- -82%
Dielectric loss up to 5%
