Internal metal electrodes are added at each end and connected by a resistive paste which is applied to the top surface of the substrate. The composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to within tolerance, by laser cutting of this resistive layer. The resistive layer is covered with a protective coating and printed with the resistance value. Finally, the two external end terminations are added. To guarantee optimum solderability the outer layer consists of a lead-tin alloy. 1999 Dec 02 VALUE 2 Philips Components Product specification Power chip resistor size 1218 PRC201 5%; 2%; 1% ORDERING INFORMATION Table 1 Ordering code indicating resistor type and packaging ORDERING CODE 2322 735 .....
