The values of the E24/E96 series are in accordance with “IEC publication 60063” Derating The power that the resistor can dissipate depends on the operating temperature Max. dissipation in percentage of rated power as a function of the ambient temperature for WR12, WR08, WR06 & WR04 Mounting Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by automatic placement systems. Chip placement can be on ceramic substrates and printed-circuit boards (PCBs). Electrical connection to the circuit is by individual soldering condition. The end terminations guarantee a reliable contact.

Therefore, it is possible to mount Surface Mount Resistors on one side of a PCB and other discrete components on the reverse (mixed PCBs). Surface Mount Resistors are tested for solderability at 235°C during 2 seconds. The test condition for no leaching is 260°C for 30 seconds. Typical examples of soldering processes that provide reliable joints without any damage are given in Figure below. Infrared soldering profile for Chip Resistors For SnAgCu series solder pase
