Page 1 of 11 ASC HQ Low ESR (HH) 006O AS Oct. 2012 Approval sheet High Q / Low ESR Series (HH) 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 HH 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 HH 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. Mobile telecommunication: Mobile phone, WLAN. b. Quality improvement of telephone calls for low b. RF module: Power amplifier, VCO. power loss and better performance. c. Tuners. 4.
