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. High voltage in a given case size.
b. High stability and reliability.
a. Snubbers in high frequency power converters.
b. High voltage coupling/DC blocking.
c. DC-DC converters.
d. Back-lighting inverters
