TYPE RESISTANCE RANGE TOL. (%) PAPER TAPE ON REEL 5000 UNITS 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. For ease of soldering the outer layer of these end terminations is a lead/tin alloy. 2003 Jul 24 Rev.5 SRC01 1 to 100 k 5 Ordering code (12NC) * The resistors have * a 12-digit ordering code starting with 2350 550. * The subsequent 2 digits indicate the resistor type and packing; see Table 1. * The remaining 3 digits indicate the resistance value: - The first 2 digits indicate the resistance value. - The last digit indicates the resistance decade in accordance with Table 2. 2 10 ...
