Multilayer Ceramic Capacitors Approval Sheet MULTILAYER CERAMIC CAPACITORS Middle & High Voltage Series (200V to 4kV) 0402 to 1812 Sizes NP0 & X7R Dielectrics Halogen Free & RoHS compliance *Contents in this sheet are subject to change without prior notice. Page 1 of 12 ASC_Middle & High Voltage Jul. 2023 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. 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. b. a. b. c. d. High voltage in a given case size. High stability and reliability.
