Philips Components Product specification Cemented wirewound resistors FEATURES * High power dissipation in small volume * High pulse load handling capabilities. APPLICATIONS * Ballast switching * Shunt in small electric motors * Power supplies. DESCRIPTION AC01/03/04/05/07/10/15/20 The resistor is coated with a green silicon cement which is not resistant to aggressive fluxes. The coating is non-flammable, will not drip even at high overloads and is resistant to most commonly used cleaning solvents, in accordance with "MIL-STD-202E" and "IEC 60068-2-45". The resistor element is a resistive wire which is wound in a single layer on a ceramic rod. Metal caps are pressed over the ends of the rod. The ends of the resistance wire and the leads are connected to the caps by welding. Tinned copper-clad iron leads with poor heat conductivity are employed permitting the use of relatively short leads to obtain stable mounting without overheating the solder joint.

MOUNTING The resistor is suitable for processing on cutting and bending machines. Ensure that the temperature rise of the resistor body does not affect nearby components or materials by conducted or convected heat. Figure 26 shows the hot-spot temperature rise of the resistor body as a function of dissipated power.

The testing also covers the requirements specified by EIA and EIAJ. 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 according to "IEC 60068-1", subclause 5.3. AC01/03/04/05/07/10/15/20 Unless otherwise specified the following values apply: Temperature: 15 C to 35 C 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 60115-1, 115-4 and 68" ; 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.
