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 UF series MLCC is used at high frequencies generally have a small temperature coefficient of capacitance,
typical within the ±30ppm/°C required for NP0 (C0G) classification, Ultra-narrow tolerance of capacitance and have
excellent conductivity internal electrode. Thus, WTC UF series MLCC will be with the feature of low ESR and high Q
characteristics.
