Cemented wirewound resistors AC01/03/04/05/07/10/15/20
FEATURES DESCRIPTION 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. 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, method 215" and "IEC 60068-2-45".
* High power dissipation in small volume * High pulse load handling capabilities.
APPLICATIONS
* Ballast switching * Shunt in small electric motors * Power supplies.

PULSE LOADING CAPABILITIES
AC01/03/04/05/07/10/15/20
How to generate the maximum allowed pulse-load from the graphs composed for wirewound resistors of the AC-types. Single pulse condition; see Fig.3 1. If the applied pulse energy in Joules or Wattseconds is known and also the R-value to be used in the application; take the R-value on the X-axis and go vertically to the curved line. From this point go horizontally to the Y-axis, this point gives the maimum allowed pulse energy in Joules/ohm or Wattsec./ohm. By multiplying this figure with -value in use gives the maximum allowed pulse-energy in Joules or Wattsec. If this figure is higher than the applied pulse-energy the application is allowed. Otherwise take one of the other graphs belonging to AC-types with higher Pn. 2. If, contrary to the information above, the applied peak-voltage and impulse times ti are known. Calculate the pulse-energy (Ep) in Joules or Wattsec. by the use of the following formula: Vp Ep = --------- x ti (Vp = peak voltage; ti = impulse-time) R By dividing this result with the Rn-value of the R in use, gives the value Wattsec./ohm on the Y-axis. Draw a line horizontally to the curved line and at the intersection the vertical line to the X-axis gives the maximum allowed Rn-value to be used in the application. If this Rn-value is higher than the R-value to be used in the application, the application is allowed. If not, take one of the other graphs belonging to AC-types with higher Pn or change the Rn-value to be used.
2
Repetitive pulse condition; see Fig.2 With these graphs we can determine the allowed pulse-energy in Watts depending on the impulse- time ti and the repetition time tp of the pulses. The parameter is the Resistance Value. If the pulse shape is known (impulse-time ti and repetition time tp), draw a line vertically from the X-axis at the mentioned ti to the line of the involved R-value. From the intersection the horizontal line to the Y- axis indicates the maximum allowed pulse-load at a certain tp/ti. If the vertical line from the X-axis crosses the applied tp/ti before reaching the R-line, this tp/ti line gives the maximum allowed pulse-energy at the Y-axis. If the applied pulse-energy is known (in Watts) and the impulse-time ti also, draw a line horizontally from the Y-axis to the crossing with the pulse-line (ti) and find the possible R-value needed in this application. The horizontal tp/ti lines give the maximum allowed pulse-load till they reach the R-line, that point indicates the maximum allowed impulse-time ti at the horizontal axis.

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. Figures 27 to 34 show the lead length as a function of dissipated power and temperature rise.

TESTS AND REQUIREMENTS Essentially all tests are carried out in accordance with the schedule of "IEC publications 60115-1 and 60115-4", category 40/200/56 (rated temperature range -40 C to +200 C; damp heat, long term, 56 days). 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 60 068-1", subclause 5.3. Table 5 Test procedures and requirements IEC 60068 TEST METHOD
AC01/03/04/05/07/10/15/20
In Table 5 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.
