Thick Film Nickel Barrier
Wraparound Surface Mount Chip
Resistors
The
ims
RXI series of thick film wraparound surface mount chip resistors is ideal
for most applications requiring an inexpensive, reliable chip resistor. The “X”
designation in the RXI series is a variable that describes the subgroup type (Low
ohm, Trimmable, etc). Please see the ordering information on the back for in-
structions. Thick film technology provides a stable resistor at a very affordable
price. The wraparound terminations include a nickel barrier layer which affords
excellent solderability and mechanical integrity. These chip resistors have the
following features:
• High stability thick film resistor element
• 96% Al

substrate material
• Nickel barrier layer for excellent solderability and mechanical integrity
• Trimmed to EIA standard values
• Tolerances to ± 0.5%
• Glass passivation of resistor element
• Available in bulk or on tape and reel
• 50 ppm available in RPI series only
