Thick Film Chip Resistors Description: The resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a resistive paste that 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 coat. Finally, the two external end terminations are added. For ease of soldering the outer layer of these end terminations is a Tin (lead free) alloy.

The testing also meets the requirements specified by EIA, EIAJ and JIS. The tests are carried out in accordance with IEC publication 68, "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 value supplied : Temperature: 15°C to 35°C. Relative humidity: 45% to 75%. Air pressure: 86kPa to 106 kPa (860 mbar to 1060 mbar). All soldering tests are performed with midly activated flux. Test Electrical Characteristics JISC5201-1: 1998 Clause 4.8 Procedure / Test Method Requirement Resistor 0Ω - DC resistance values measurement - Temperature Coefficient of Resistance (T.C.R) Within the specified tolerance Refer to t1 : 20°C+5°C/-1 °C; t2 : -55°C or +155°C "QUICK REFERENCE
