High temperature operation capacitors. (At least +200C). High voltage capacitors. (Up to 10 kV for chip capacitors). Capacitors intended for gluing to PCB using conductive glue. Commonly they have silver-palladium or gold terminals). (lateral field capacitors). Capacitors for microwave applications Low ESR capacitors (reverse-geometry MLCCs). Forming the terminal electrodes along the long dimension of the device widens and shortens the current path between terminations, thus reducing inductance and resistance. comprise 2 or 4 capacitors and contribute in reduction of Chip capacitor arrays mounting cost of circuit assembly. 4-capacitors array may be as small as 2.01.251.0 mm. 4-capacitors arrays: ceramic multilayer (left) and film (right) The X2Y Circuit Architecture (Syfer Technology Ltd.) is a patented technology. It is characterized by presence of additional ground electrodes between the regular electrodes and works both as an a single X capacitor (line to line decoupler) and as two Y capacitors (line to ground filters) simultaneously. An application can use the X capacitor and the two Y capacitors together or separately in a circuit. The needs of the circuit designer determine the attachment or non-attachment of the appropriate corresponding ground terminations. Advantages: Replaces 2 or 3 capacitors with one device Matched capacitance line to ground on both lines
