Key Points for Selecting Ceramic Chip Capacitors (MLCC) 3

that the capacity change of the capacitor is nonlinear at this time

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

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  diode

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 capacitor has 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

Despite its unstable capacity, 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 other technical specifications of Z5U capacitor are as follows:

Working temperature range+10 ℃ -+85 ℃

Temperature characteristics+22% -56%

dielectric loss

Maximum 4%

Four Y5V capacitors

Y5V capacitor is a universal capacitor with certain temperature limitations, and its capacity can vary by+22% to -82% within the range of -30 ℃ to 85 ℃

The high dielectric constant of Y5V allows for the fabrication of capacitors up to 4.7 μ F in smaller physical dimensions

The other technical specifications of Y5V capacitors are as follows:   diode

Working temperature range -30 ℃ -+85 ℃

Temperature characteristics+22% ---82%

dielectric loss

Maximum 5%
