Thick Film Wraparound Surface
Mount Chip Resistors for
Epoxy and Solder Mount
Features
Thick film technology
Full Wraparound and
Single Wraparound with
Groundplane
Ideal for epoxy
attachment. Solder
coating also available
Resistance values from
1 ohm to 1000 Gigohm
Tolerances to 1 %
TCR to 100 ppm/oC
The
ims
RCX, HCX series of thick film wraparound surface mount chip resistors is ideal
for most applications requiring epoxy or solder die attaching methods. Thick film
technology provides a stable resistor at a very affordable price. The “X” designation in
each series is a variable that allows for specifying the termination metalization. Please
see the ordering information on the back for instructions. The wraparound terminations
use gold, platinum gold, platinum silver, or platinum silver with solder coating. These chip
resistors have the following features:
• High stability thick film resistor element
• 96% Al2O3substrate material
• Platinum silver(PtAg), platinum gold(PtAu), solder coated platinum silver, solder coated
platinum gold, or gold(Au) terminations
• Tolerances to ± 1%
• Passivated resistor element available where not standard
• Available in bulk, tape and reel, and waffle pack
SG - Single wrap
with groundplane
