CO N STRUCTION Th e resistors are constructed using outstanding TCR level material, which makes Yageo PR 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. Marking is printed on the top side of the resistor. Finally, the three external terminations (Cu / Ni / matte Tin) are added, as shown in Fig. 5. www.yageo.com Aug. 22, 2014 V.0
