CONSTRUCTION
The resistors are constructed using outstanding TCR level material, which makes Yageo PR/PF 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 two external terminations (matte Tin) are added. See fig. 3.
