Resistance range RC04H RC14H RC24H 1206 (3216) 0805 (2012) 0603 (1608) 100 to 1 M; E24/E96 series 0.25% Resistance tolerance APPLICATIONS * Measuring instruments * Power supplies * EDP * Telecom. 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 high voltage 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. Temperature coefficient: 100 x 10-6/K 100 R 1 M Absolute maximum dissipation at Tamb = 70 C 0.125 W 0.10 W 0.063 W Maximum permissible voltage (DC or RMS) 200 V 150 V 50 V Climatic category (IEC 60068) Basic specification 55/125/56 IEC 60115-8 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. 2001 Apr 27 Rev.2 2 www.phycomp-components.com Phycomp Product specification High-precision chip resistors sizes 1206, 0805 and 0603 RC04H/RC14H/RC24H 0.25% ORDERING INFORMATION Table 1 Ordering code indicating resistor type and packing TYPE TOL.

The testing also covers the requirements specified by EIA and EIAJ. Relative humidity: 45% 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 60115-8 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. The tests are carried out in accordance with IEC publication 60068, "Recommended basic climatic and mechanical robustness testing procedure for electronic components" and under standard atmospheric conditions in accordance with "IEC 60068-1", subclause 5.3. All soldering tests are performed with mildly activated flux.
