Multilayer Ceramic Capacitors Approval Sheet MULTILAYER CERAMIC CAPACITORS Middle & High Voltage Series (200V to 4kV) 0402 to 1812 Sizes NP0, X7R & Y5V Dielectrics Halogen Free & RoHS compliance *Contents in this sheet are subject to change without prior notice. Page 1 of 13 ASC Middle & High Voltage 003AE Aug. 2018 Multilayer Ceramic Capacitors Approval Sheet 1. INTRODUCTION WTC middle and high voltage series MLCC is designed by a special internal electrode pattern, which can reduce voltage concentrations by distributing voltage gradients throughout the entire capacitor. This special design also affords increased capacitance values in a given case size and voltage rating. Chips size 1206 and larger to use on reflow soldering process only. Capacitors with X7R dielectrics are not intended for AC line filtering applications. Capacitors may require protective surface coating to prevent external arcing. 2. FEATURES 3. APPLICATIONS a. High voltage in a given case size. a. Snubbers in high frequency power converters. b. High stability and reliability. b. High voltage coupling/DC blocking. c. DC-DC converters. d. Back-lighting inverters 4.
