A multilayer ceramic capacitor includes a ceramic body including an active portion including dielectric layers and internal electrodes that are alternately stacked and a margin portion disposed on outer surfaces of the active portion; and external electrodes disposed on outer surfaces of the ceramic body. The margin portion includes an inner half adjacent to the active portion and an outer half adjacent to the edge of the ceramic body, and a porosity of the inner half is greater than a porosity of the outer half.

Multilayer ceramic capacitor and board having the same

A multilayer ceramic electronic component includes a ceramic body including dielectric layers and first and second internal electrodes disposed to face each other with respective dielectric layers interposed therebetween, and external electrodes disposed on outer surfaces of the ceramic body. Opposite edge portions of at least one or more of the first and second internal electrodes in a width direction of the ceramic body are thicker than a central portion thereof, and a ratio (T/T) of a thickness (T) of the edge portion to a thickness (T) of the central portion satisfies 1.0&#x3c;T/T&#x2266;2.0.

Multilayer ceramic electronic component

A low-temperature sintering dielectric composition contains barium titanate (BaTiO) as a main ingredient and accessory ingredients including 1.0 to 2.0 mol % of barium carbonate (BaCO), 0.5 to 1.0 mol % of at least one rare earth oxide selected from the group consisting of YO, HoO, DyO, and YbO, 0.1 to 1.0 mol % of manganese oxide (MnO), and 1.0 to 2.0 mol % of borosilicate based glass, based on 100 mol % of the main ingredient.

Low-temperature sintering dielectric composition and multilayer ceramic capacitor formed thereof

The present invention relates to borosilicate glass compositions for a sintering agent, dielectric compositions containing the borosilicate glass compositions and a multilayer ceramic capacitor using the dielectric compositions. Borosilicate glass compositions for a sintering agent according to an aspect of the invention include an alkali oxide, an alkaline earth oxide and a rare earth oxide, can sinter ceramic dielectrics at low temperatures and improve the hot insulation resistance of a multilayer ceramic capacitor. Correspondingly, dielectric compositions including these borosilicate glass compositions and a multilayer ceramic capacitor using the dielectric compositions can be sintered at a low temperature of 1100&#xb0; C. or less and have high hot insulation resistance, thereby ensuring high levels of reliability.
