Abstract
Description
[001]本出願は、2019年2月13日の出願日を有する米国仮特許出願第62/804,944号の出願利益を主張するものであり、その全体が参照により本明細書に組み込まれる。
[008]当業者にとっての本発明の最良の形態を含む、本発明の完全かつ実施可能な開示は、添付の図面を参照して、本明細書の残りの部分においてより具体的に記載される。
[0017]一般的に言えば、本発明は、回路板に取り付けるための表面実装積層セラミックコンデンサなどの積層セラミックコンデンサに関する。積層コンデンサは、複数の誘電層および複数の内部電極層を含み、内部電極層は、導電性ビアを使用してそれぞれの外部端子に接続される。本発明者らは、単一の本体またはパッケージ内の要素の特定の構成が、いくつかの利点を提供できることを発見した。例えば、以下にさらに論じられるように、本発明のコンデンサは、表面実装コンデンサとして回路板上に搭載されてもよく、回路板上により小さい接地面積を提供し得る。ひいては、これにより回路板のサイズの低減も可能にすることができる。
[0068]例えば、図1Aは、4×4構成のコンデンサ20を示す。したがって、コンデンサは、上面および底面の1次元に沿った4つの外部端子と、別の次元に沿った4つの端子とを含む(図示せず)。この点に関して、コンデンサは、合計して、上面に16個の外部端子32、24と、底面に16個の対応する外部端子とを含み、上面における外部端子32、34は、底面における対応する外部端子に、電気的に接続され得る。したがって、図1Aのコンデンサ20は、上面に少なくとも1つの第1の極性端子と、少なくとも1つの第2の逆極性端子とを含み得る。図示されていないが、底面はまた、少なくとも第1の極性端子および第2の逆端子を含み得る。
