Characteristics Electrical
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
styles
(Lo Ohm, Power, or Ultra Precision)
while
staying
within
the
new
standard circuit board land pattern

guidelines now accepted by the
wirewound resistor industry. Each
size offers low profile case design
with
flexible
tinned
terminations for
copper
reliable solder
joints. All styles utilise a fully
welded construction technique,
unlike other designs that rely solely
on tinned termination connections.
These
features
allow
the
S
Series to withstand the higher
temperatures
associated
with
reflow, vapour phase, or infrared
(IR)
