PAC.. Series Vishay Draloric Cemented Wirewound Precision Resistors FEATURES High power dissipation in small volume Ideal for pulse application TCR ± 100 ppm/K Maximum permissible hot spot temperature is 275 °C Lead (Pb)-free Tolerance 1 % Compliant to RoHS Directive 2002/95/EC 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-inflammable, will not drip even at high overloads and is resistant to most commonly used cleaning solvents, in accordance with IEC 60068-2-45.
