QUICK REFERENCE DATA VALUE DESCRIPTION ARC241 Resistance range Resistance tolerance and E-series Temperature coefficient Absolute maximum dissipation per resistive element at T amb = 70 C Maximum permissible voltage Climatic category (IEC 60068) Basic specification R-Array overview TYPE ARC241 ARC242 ARV241 ARV242 TERMINATION TECHNOLOGY concave concave convex convex SIZE 4 x 0603 4 x 0603 4 x 0603 4 x 0603 5%; E24 series 200 x 10-6/K ARV241 ARC242 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, external end terminations are added. For ease of soldering the outer layer of these end terminations is a lead-tin alloy. ARC241/ARC242 ARV241/ARV242 handbook, 2 columns R1 R2 R3 R4 CCA862 R1 = R2 = R3 = R4.

For values of 100 or greater the first 2 digits apply to the resistance value and the third indicates the number of zeros to follow. Example MARKING 12R 124 000 4-DIGIT MARKING For values up to 976 the R is used as a decimal point. For values of 1 K or greater the first 3 digits apply to the resistance value and the fourth indicates the number of zeros to follow.

The testing also covers the requirements specified by EIA and EIAJ. The tests are carried out in accordance with IEC publication 60 068, "Recommended basic climatic and mechanical robustness testing procedure for electronic components" and under standard atmospheric conditions according to "IEC 60068-1", subclause 5.3. Unless otherwise specified the following values apply: Array chip resistors size 4 x 0603 Temperature: 15 C to 35 C Relative humidity: 25% to 75% Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar). In Table 4 the tests and requirements are listed with reference to the relevant clauses of "IEC publications 60 115-8 and 60068"; a short description of the test procedure is also given. In some instances deviations from the IEC recommendations were necessary for our method of specifying. All soldering tests are performed with mildly activated flux.
