Ceramic capacitors, commonly referred to as ceramic caps or simply ceramics, are a type of fixed capacitor used in electronic circuits. They consist of two metal electrodes separated by a layer of ceramic material, typically made from barium titanate. This unique construction enables them to offer a range of benefits including stability, low cost, and compact size. The key characteristics of ceramic capacitors include: High capacitance values Low electrical losses Resistance to environmental factors such as temperature and humidity Ceramic capacitors are widely used in various applications due to their versatility. They can be found in everything from consumer electronics and automotive systems to medical equipment and industrial control circuits. The most common types of ceramic capacitors include: Class 1 (high quality, stable) Class 2 (medium quality, some instability at high temperatures) Class 3 (low quality, significant instability) Despite their widespread use, ceramic capacitors do have some limitations. They can be prone to cracking or breaking under mechanical stress and may experience a decrease in capacitance over time due to aging.
