Type S Series
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 copper terminations for
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) manufacturing processes without
degradation.

How to Order
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.
