Tyco introduces a range of surface
mount power resistors to meet
today's circuit design needs. One
design concept allows an engineer
to
choose
from
three
the
styles
new
(Lo Ohm, Power, or Ultra Precision)
while
staying
within
standard circuit board land pattern
guidelines now accepted by the
wirewound resistor industry. Each
size offers low profile case design
with
flexible
tinned
copper
terminations for
reliable solder

welded construction technique,
unlike other designs that rely solely
on tinned termination connections.
These
features
allow
the
S
Series to withstand the higher
temperatures
(IR)
associated
with
reflow, vapour phase, or infrared
manufacturing
processes
without degradation.

Cleaning Conditions
After soldering use cleaning solvents such as chlorosen, dyefreon, suitable aqueous or
semi aqueous cleaner.
Storage
To prevent damage to the electrode, be sure to observe the following cautions for storage.
• Store in 40°C maximum ambient temperature, and 70% maximum R.H.
• For maximum possible shelf life do not disturb polythene sleeve until you are ready to use.
• Store where there are no harmful gases containing sulphur or chlorine.
