Open Mode Series
1. INTRODUCTION
WTC open-mode 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
open-mode pattern to prevent circuit leakage when focused to failure in a board flex situation.
2. FEATURES
b.
c.
d.
High voltage in a given case size.
Circuit open during product cracking.
High stability and reliability.
3. APPLICATIONS
a.
b.
c.
High current applications.
Power supply and related industries
The other mechanical stress concerned products.
