■½用上の注意 Precautions for Use
インダクタに強い力、過度の衝撃を加えると電気、磁気特性が変化することがありますので、搭載時及び搭載後に過度の衝撃が加わらないようにして下さい。
コイルボビンにフェライトを½用している½品のため、スイッチング周波数により、発熱量が異なるので½用温度が85℃以下になるようにご½用下さい。
●
Avoid strong pressure or excessive shock at mounting or after mounting because electric/magnetic characteristics may change if it is applied to the inductors.
●
Due to the products using ferrite for coil bobbins, use them 85 ℃ or under of inductor temperature because the volume of generating heat varies depending on
switching frequency.
