CONSTRUCTION
The resistors are constructed using outstanding TCR level material, which makes Yageo P A 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.

FUNCTIONAL DESCRIPTION
OPERATING TEMPERATURE RANGE
PA2512 Range: –55°C to +170°C
POWER RATING
Standard rated power at 70°C:
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 =
(PxR )
Where
V = Continuous rated DC or
AC (rms) working voltage (V)
P = Rated power (W )
R = Resistance value (
Ω
)
