PF
The resistors are constructed
using outstanding TCR level
material, which makes Yageo PF
resistors excellent for current
sensing application in battery
charger circuit & DC-DC
converter.
The composition of the resistive
2010 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 (Ni / matte Tin) are
added, as shown in Fig. 4.
