The component lead termination of this product range is lead- free compatible, therefore the converter can be soldered in a lead-free soldering process. The devices are fully compatible with CECC00802 to 280°C which allows them to be placed and reflowed with IC’s, thus reducing time and cost in production. Co- planarity of the lead positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged.
