is: RC2512FK-0756RL.
NOTE
1. The “L” at the end of the code is only for ordering. On the reel
label, the standard CTC will be mentioned an additional stamp
“LFP”= lead free production.
2. Products with lead in terminations fulfil the same requirements
as mentioned in this datasheet.

CONSTRUCTION
The resistors are constructed out of
a high-grade ceramic body. Internal
handbook, 4 columns
metal electrodes are added at each
end and connected by a resistive
H
paste. The composition of the paste
is adjusted to give the approximate
I2
required resistance and laser cutting
of this resistive layer that achieves
Fig. 3 Chip resistor construction
tolerance trims the value. The
resistive layer is covered with a
protective coat and printed with the
resistance value. Finally, the two external terminations (pure Tin) are added. See fig. 3.

FUNCTIONAL DESCRIPTION
POWER RATING
RC2512 rated power at 70°C is 1 W
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)
