CONSTRUCTION
The resistors are constructed using outstanding TCR level material, which makes Yageo PR/PF/PH resistors
excellent for current sensing application in battery charger circuit & DC-DC converter.
The composition of the resistive material is adjusted to give the approximate required resistance and is
covered with a protective coating, which printed with the resistance value.
Finally, the three external terminations (Cu / Ni / matte Tin) are added, as shown in Fig. 4.
