Ceramic capacitors have a dielectric made of ceramic materials. General specifications include configuration, capacitance type, and technology. There are two basic configurations for ceramic capacitors: leaded and surface mount. Leaded ceramic capacitors have leads for connections to circuits. Surface mount capacitors or chip capacitors do not. Ceramic capacitor technologies are categorized as monolithic, multilayer, or wound. Monolithic components use a dielectric made of a single layer. Multilayer devices are made of many layers and are small in size. They provide excellent temperature stability and frequency characteristics. Wound capacitors are built by winding foils, sometimes by hand. In terms of technology, there are two choices: fixed and variable. Fixed ceramic capacitors have a nonadjustable capacitance value. With variable ceramic capacitors, specific capacitance values are set with a potentiometer. |
Products & Services Related to Ceramic Capacitors
Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do not.
Capacitors
Capacitors are electronic components used for storing charge and energy. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric.
Chip Capacitors
Chip capacitors or surface mount capacitors do not have leads.
Film Capacitors
Film capacitors are insulated with polyester, polycarbonate, polypropylene, polystyrene, or other dielectric materials.
High Voltage Capacitors
High voltage capacitors are used for storing charge and energy in high voltage applications.
Tantalum Capacitors
Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics.
Ultracapacitors
Ultracapacitors store charges (energy) by physically separating positive and negative charges (unlike batteries which do so chemically). Very high power densities can be achieved by this method.
