Basic specication IEC 60115-8 DESCRIPTION The resistors are constructed on a high grade ceramic body (aluminium oxide). 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 Feb 10 309Philips Components Product specication Power chip resistor PRC221 size 2512 5% 2% ORDERING INFORMATION Table 1 Ordering code indicating resistor type and packaging ORDERING CODE 2322 762 .....
