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 layer that is applied to the top surface of the substrate. The  
composition of the resistive layer is adjusted to give the approximate resistance required and the value is  
trimmed to nominated value within tolerance which controlled by laser trimming of this resistive layer.  
The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For  
environmental soldering issue, the outer layer of these end terminations is a Lead-free solder .

4-digits marking for 2512, 2010, 1210, 1206, 0805 size  
For E24+E96, each resistor is marked with a four digits code on the protective coating to designate the  
nominal resistance value. For values below 97Ω6 the R is used as a digit. For values of 100Ω or greater, the  
first 3 digits are significant, the fourth digit indicates the number of multiple to follow.

FUNCTIONAL DESCRIPTION  
Product characterization  
Standard values of nominal resistance are taken from the E192 & E24 series for resistors with a tolerance of  
±0.5%, ±0.25%, ±0.1%. The values of the E24/E192series are in accordance with “IEC publication 60063”  
Derating  
The power that the resistor can dissipate depends on the operating temperature; see Fig.2  
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.

SOLDERING CONDITION  
The robust construction of chip resistors allows them to be completely immersed in a solder bath of 260°C for 10  
seconds. 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 within lead-free solder bath. 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 Fig 3. and Table 1.
