Internal metal electrodes are added at each end and connected by a resistive paste. The composition of the paste is adjusted to give the approximate required resistance and laser cutting of this resistive layer that achieves tolerance trims the value. The resistive layer is covered with a protective coat and printed with the resistance value. Finally, the two external terminations are added.

Measure resistance at +25C or specified room temperature as R1, then measure at -55C or +155C respectively as R2. Determine the temperature coefficient of resistance from the following formula: Thermal Shock ACCEPTANCE STANDARD Formula Refer to table 2 R2-R1 T.C.R. = ------------------------- x106 (ppm/C) R1(t2-t1) Where t1=+25C or specified room temperature t2=-55C or +155C test temperature R1=resistance at reference temperature in ohms R2=resistance at test temperature in ohms At -553C for 2 minutes and at +1552C for 2 minutes as one cycle.
