MULTILAYER CERAMIC CAPACITOR

摘要

A multilayer ceramic capacitor whose external electrodes are each provided with a solder non-adhesion film made of material to which solder does not adhere, in a manner continuously covering the entire surface of the end face, and optionally the entire surface of the curved face thereof. The multilayer ceramic capacitor, with certainty, allows for suppression of noise accompanying electrostriction.

主权项

1. A multilayer ceramic capacitor comprising a dielectric chip made of dielectric ceramics and having a roughly rectangular shape, as well as external electrodes respectively positioned on opposing ends thereof, where ends of parts of multiple internal electrode layers built into the dielectric chip in a manner not contacting each other are connected to one external electrode, while ends of the other parts are connected to the other external electrode, wherein:
each of the external electrodes has an end face of roughly rectangular shape covering an end face of the dielectric chip, a side face of roughly quadrangular cylinder shape covering a part of four side faces of the dielectric chip, and a curved face of roughly arc cross-section present between the end face and side face; and each of the external electrodes has a solder non-adhesion film made of material to which solder does not adhere: (1) in a manner continuously and exclusively covering an entire surface of the end face and an entire surface of the curved face; (2) in a manner continuously and exclusively covering an entire surface of the end face and a part of the curved face; or (3) in a manner exclusively covering an entire surface of the end face.
