Multilayer Ceramic Capacitors
Approval Sheet
1. INTRODUCTION
MLCC consists of a conducting material and electrodes. To manufacture a chip-type SMT and achieve
miniaturization, high density and high efficiency, ceramic condensers are used.
WTC RH series MLCC are used at high frequencies generally and have a small temperature coefficient of
capacitance, typical within the ±30ppm/°C required for X8G classification and have internal electrodes of excellent
conductivity. Thus, WTC RH series MLCC will have the feature of low ESR and high Q characteristics.
WTC RH series have high reliability characteristic, life test condition: 150℃ / 2000hrs / 2xRated Voltage.
