Abstract
The present disclosure provides a multilayer electronic component which may improve a break down voltage (BDV) characteristic by adjusting a ratio of a content of an element included in a first or second region of a dielectric layer to reduce a difference in dielectric grain size dispersion and grain density in the first or second region.
Claims22
A multilayer electronic component comprising:
- a body having first and second surfaces opposing each other in a first direction, third and fourth surfaces connected to the first and second surfaces and opposing each other in a second direction, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other in a third direction, and including a dielectric layer and first and second internal electrodes alternately disposed in the first direction while having the dielectric layer interposed therebetween;
- and
- external electrodes respectively disposed on the third and fourth surfaces,
- wherein the body includes a capacitance formation portion in which the dielectric layer and first or second internal electrode overlap each other in the first direction, a first margin portion disposed on one surface or the other surface of the capacitance formation portion in the second direction, and a second margin portion disposed on one surface or the other surface of the capacitance formation portion in the third direction,
- a first region is a region of the dielectric layer that is included in the capacitance formation portion and a second region is a region of the dielectric layer that is included in the first margin portion,
- the first or second region includes manganese (Mn) and titanium (Ti), and
- a ratio of a content of manganese (Mn) to a content of titanium (Ti) in the second region is more than 1 time and 1.9 times or less compared to a ratio of a content of manganese (Mn) to a content of titanium (Ti) in the first region.
