RoHS compliant with complete lead free APPLICATION Medical equipments Testing & Measuring instruments Communication devices Base station, AP Router, Power supply & Server High end audio system DESCRIPTION The resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a resistive layer that is applied to the top surface of the substrate. The composition of the resistive layer is adjusted to give the approximate resistance required and the value is trimmed to nominated value within tolerance which controlled by laser trimming of this resistive layer. The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For environmental soldering issue, the outer layer of these end terminations is a Lead-free solder . Fig 1. Construction of Chip-R Page 2 of 8 ASC TF V02 Sep - 2014
