Understanding Chip Capacitors

Chip capacitors have thermal properties characteristic ceramic materials. Originally processed at high temperature, chips can withstand exposure to temperatures limited only by the termination material (which is processed at approximately 800°C). Of importance is the rate at which chips are cycled through temperature changes.
