CONSTRUCTION
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 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. 4.

Standard rated power at 70°C:
PF0603 = 1/10W
PF0805 = 1/8W
PF1206 = 1/4W
PF2010 = 1/2W
PF2512 = 1W
PF4527 = 2W
For detail power value, please refer to Table 2.
RATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V = √(P X R)
Where
V = Continuous rated DC or
AC (rms) working voltage (V)
P = Rated power (W)
R = Resistance value (X)
