Abstract
【解決手段】 積層型インダクタ1は、直方体の形状をなす素体7を備えており、素体7の寸法は、長手方向の長さ(L)、高さ方向の長さ(H)、幅方向の長さ(W)が、それぞれL≦0.6mm、H≦0.3mm、W≦0.3mmである。端子電極15a,15bは、素子7の頂点11を覆い、両端側の端面9bから側面13に回り込むように配設されている。この端子電極15a,15bの頂点の曲率半径Rは、H又はWの10%以上かつ20%以下とされている。
【選択図】 図1
Description
0603タイプ及び0402タイプの積層型インダクタについて、電極頂点の曲率半径Rを適宜調整して各曲率半径Rを有するサンプルを作製し、実装基板上にリフロー半田付けによって実装する試験を行った。
表1及び表2より、0603タイプ、0402タイプ共に、曲率半径Rが素子の幅(W)に対して20%を上回り、25%、30%となった場合にはチップ立ち不良が発生することが判る。
