1. The “L” at the end of the code is only for ordering. On the reel label, the standard CTC or 12NC 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.
3. Products with lead in terminations will be phased out in the coming months (before July 1st, 2006)

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

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
RC1206 rated power at 70°C is 1/4 W
R
ATED 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)
