A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
These are some limitations of ceramic capacitors: They offer less capacitance value to a few microfarads. The dielectric in them can be damaged over high voltages. They may have voltage-dependent capacitance changes. Due to the construction using a ceramic material, there is a risk of cracking or damage in case of mechanical loss.
They have capacitance values in the range of 10pF to 100μF. Ceramic Chip Capacitors: These ceramic chip capacitors are widely used in consumer electronics, communication devices, and also in different digital applications. Ceramic capacitors are categorized into multiple dielectric classes based on the type of dielectric material used.
Bear in mind that capacitors that are measured in nano farad and microfarad are simple to check. However, you will need a special type of multimeter to measure small ceramic capacitors (measured in picofarad). In this section, we will show you the straightforward and easiest way to test those capacitors.
So, grab your multimeter and follow the steps below. Disconnect your ceramic capacitor from the device and ensure it is fully discharged. Check its capacitance value that is displayed on the capacitor. Choose the capacitance mode on your digital multimeter. Connect the testing probes with the capacitor’s terminals.
Data sheets of ceramic capacitors only specify the impedance magnitude . The typical impedance curve shows that with increasing frequency, impedance decreases, down to a minimum. The lower the impedance, the more easily alternating currents can pass through the capacitor.
