Page 1 of 16 ASC Ultra HQ Low ESR (RF) 014AC AS Sep. 2017 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 RF 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 and have excellent conductivity internal electrode. Thus, WTC RF series MLCC will be with the feature of low ESR and high Q characteristics. 2. FEATURES 3. APPLICATIONS a. High Q and low ESR performance at high frequency. a. Telecommunication products & equipments: Mobile b. Ultra low capacitance to 0.1pF. phone, WLAN, Base station. c. Can offer high precision tolerance to 0.05pF. b. RF module: Power amplifier, VCO. d. Quality improvement of telephone calls for low c. Tuners. power loss and better performance. 4.
