■Internal electrode structure

  • Mid-voltage range (Straight structure)
    Secure break-down voltage margin with proper suitable dielectric thickness for each rated voltage.
  • Mid-voltage range (Dual cascade structure)
    Achieves high rated voltage by series connection of two capacitor units in one MLCC to divide applied
    voltage into two. Also, it has good protection against transient voltage.
  • Mid-voltage range (Triple cascade structure)
    Achieves high rated voltage by series connection of three capacitor units in one MLCC to divide applied
    voltage into three. Excellent safety against high voltage.

The multi cascade design prevents short circuit failure which results in excellent reliability. Specifications
