What is a capacitor?

A capacitor is one of the most commonly used components in electronics and electrical engineering. It consists of two conductive covers that are separated from each other by a dielectric, a non-conductive material. This dielectric prevents the covers from coming into contact with each other. The covers are usually made of metal. If a DC voltage is applied, positive and negative charges collect on the covers. Even if the power supply is interrupted, the charges remain stored, which is referred to as a charged capacitor.

Ceramic capacitors: Important information

What is special about ceramic capacitors?

Ceramic capacitors are one of the most commonly used energy storage elements in electronics and electrical engineering. Unlike other capacitors, they are built up in layers, which is due to the brittle mechanical properties of ceramics. They have a relatively small capacitance, often in the range of a few picofarads to a few microfarads. Nevertheless, they are characterised by high temperature stability, long service life and reliable operation. Another advantage is their extremely low capacitive tolerance, which means that they store their nominal capacitance very accurately.

Advantages of ceramic capacitors

- High temperature stability: Ideal for applications with high temperature fluctuations.

- Low capacitive tolerance: High accuracy in capacitance.

- Low losses: Stored energy is retained over a longer period of time.

- Versatile applications: Particularly suitable for systems with high frequencies such as televisions and radios.

Applications of ceramic capacitors

Ceramic capacitors are used in many areas, including:

- Voltage filtering: They smooth out voltages in electronic circuits.

- High frequency applications: Ideal for devices such as televisions and radios.

- Various circuits: Ceramic capacitors can be connected in series and parallel, depending on the application.

Types of ceramic capacitors

Ceramic capacitors are available in various packages, including:

- Through-hole mounting (THT): For classic soldering methods.

- Surface mount (SMT): For modern SMD technology.

Specifications of ceramic capacitors

Here are some common specifications for ceramic capacitors and what they mean:

- Capacitance (470pF, 100nF, 82pF, 4.7pF, 8.2pF): This is the capacitor's ability to store electrical charge. The unit is farad (F), where pF (picofarad) and nF (nanofarad) are smaller units.

- Nominal voltage (50V): This is the maximum voltage the capacitor can withstand without being damaged.

- Tolerance (±10%): This indicates how accurate the capacitance of the capacitor is compared to its rated value. A tolerance of ±10% means that the actual capacitance can be up to 10% more or less than the nominal value.

- Mounting type (THT): This refers to the way the capacitor is mounted. THT (Through-Hole Technology) means that the capacitor is mounted through holes on the circuit board.

- Pitch (2.54mm): This is the distance between the capacitor's connection pins.
