Technology
Multi-layer Ceramic Capacitor constructed by depositing alternative layers of ceramic dielectric materials and internal metallic electrodes, by advanced ceramic manufacturing technology and co-firing into an indestructible homogeneous body, then completed with application of mta and terminations which are fired on to assure that permanent connection of individual internal electrodes are in parallel. The terminations also can be nickel-plated and then solder plated to give the chip capacitors nickel-barrier terminations which have much better leaching resistance during soldering.
Reliable performances are built-in through exact formulation of dielectric powders, preperation of conductive paste, advanced automatic manufacturing and strict quality control to assure excellent control in dielectric thickness, electrode integrity and electrode-to-termination continuity.
