X7R Capacitor

X7R capacitor

The X7R capacitor is known as a temperature stable ceramic capacitor. When the temperature is between - 55 ℃ and 125 ℃, the capacity change is 15%. It should be noted that the capacitor capacity change is non-linear at this time.

The capacity of X7R capacitors varies under different voltage and frequency conditions, and it also varies over time, varying by approximately 1% every 10 years Δ C. It shows a change of about 5% in 10 years.

X7R capacitors are mainly used in industrial applications with low requirements, and their capacity changes are acceptable when the voltage changes. Its main characteristic is that the electrical capacity can be relatively large in the same volume. The following table shows the selectable capacity ranges for the X7R capacitor.
