CGA Conductive Epoxy Automotive-Rated MLCCs TDK CGA Conductive Epoxy Automotive-Rated MLCCs are conductive glue-mounted rather than solder-mounted, making them ideal for high-temperature environments that require high reliability, such as automotive applications. These AEC-Q200 devices allow for more flexibility during periods of expansion and contraction. The use of a non-solder attachment reduces the thermal expansion differences between the substrate, MLCC, and solder fillet. TDK CGA MLCCs are also used in applications that cannot be subjected to the heat of the solder paste mounting process, such as LCD panels, organic EL and LED displays, and CCD devices, which are especially sensitive to high temperatures.
