Abstract
【解決手段】陽極部と誘電体被膜と陰極部とを有するコンデンサ素子と、陽極リードフレームと、陰極リードフレームと、該陽極及び陰極リードフレームの少なくとも一部と前記コンデンサ素子を被覆する外装樹脂と、を具える固体電解コンデンサであって、前記コンデンサ素子と導電性接着材を介して対向している陰極リードフレーム対向部には、コンデンサ素子側開口部と外装樹脂側開口部の間に他の部分とは直径が小さい絞り部を有している貫通孔が設けられ、該貫通孔に導電性接着材が形成されたことを特徴とする。
【選択図】図4
Description
[性能評価]
図3に示すように、陰極リードフレーム平行部4s1の中央部に貫通孔41を配し、さらにその周りに同心円状に4個(計5個)の同一形状の貫通孔41を配置した陰極リードフレーム4を備えた固体電解コンデンサを実施例1として30個作製した。滞留部41aの直径、絞り部41bの最狭部の直径、排気部41cの直径は、それぞれ0.6mm、0.2mm、0.4mmである。また、貫通孔41の延在方向における滞留部41a、絞り部41b、排気部41cの長さは、それぞれ0.02mm、0.02mm、0.07mmである。また、従来例として貫通孔41を設けていない陰極リードフレーム4を備えた固体電解コンデンサも30個作製した。
Claims (4)
