ESCRIPTION
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.
MERITEK
UQ series MLCC is used at high frequencies
generally have a small temperature coefficient of
capacitance, typical within the ±30ppm/ºC required for
NPO (COG) classification and have excellent
conductivity internal electrode. Thus,
MERITEK
UQ
series MLCC will be with the feature of low ESR and high
Q characteristics
