with lead-free terminations made
by thick film process.
APPLICATIONS
All general purpose application
FEATURES
RoHS compliant
- Products with lead free
terminations meet RoHS
requirements
- Pb-glass contained in electrodes
- Resistor element and glass are
exempted by RoHS
Reducing environmentally
hazardous wastes
High component and equipment
reliability
Saving of PCB space
None forbidden-materials used
in products/production
Halogen Free Epoxy
ORDERING EXAMPLE
The ordering code of a RC1206
chip resistor, value 56 X with
±1% tolerance, supplied in 7-inch

NOTE
1. All our RSMD products meet RoHS
compliant. "LFP" of the internal 2D reel
label mentions "Lead Free Process"
2. On customized label, "LFP" or specific
symbol printed and the optional "L" at
the end of GLOBAL PART NUMBER /

CONSTRUCTION
The resistor is constructed on top
of a high-grade ceramic body.
Internal metal electrodes are added
on each end to make the contacts to
the thick film resistive element. The
composition of the resistive element
is a noble metal imbedded into a
glass and covered by a second glass
to prevent environment influences.
The resistor is laser trimmed to the
rated resistance value. The resistor
is covered with a protective epoxy
coat, finally the two external
terminations (matte tin on Ni-
barrier) are added. See fig.3

RC1206 rated power at 70°C is 1/4 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)
or max. working voltage whichever is less
Where
V=Continuous rated DC or
AC (rms) working voltage (V)
P=Rated power (W)
R=Resistance value (X)
