Thick Film Wraparound
Extended Power
Surface Mount
Chip Resistors for Epoxy and Solder Mount
The
ims
Super (S) RCX Series of thick film
non-magnetic
wraparound surface mount chip resistors are ideal
for most applications requiring extra power density within the same footprint. Special processing allows for
twice
the power handeling of other resistors in the same size package. Thick film technology provides a stable
resistor at a very affordable price. These resistors are suitable for epoxy or solder die attachment methods. The
‘X’ designation in each series is a variable that allows for specifying the terminal metallization. Please see
ordering information on page two for instructions.
This series features
ims’
optional
non-magnetic
Ultra Leach Resistant (ULR) type terminals which offer added
performance over our standard leach resistant PtAg terminals and have been proven to maintain their integrity
in the most extreme solder reflow environments, including high temperatures and multiple reflows. They have
been shown to withstand up to 15 minutes in 60/40 solder at 260°C.
