Thick Film Wraparound Surface Mount
Chip Resistors for Epoxy and Solder Mount
The
ims
RCX, HCX Series of thick film
non-magnetic
wraparound surface mount chip resistors are ideal for
most applications requiring epoxy or solder die attachment methods. Thick film technology provides a stable
resistor at a very affordable price. 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.
These chip resistors have the following features:
• High stability thick film resistor element
• 96% Al²O³ substrate material
• Tolerances to ±1%
• Available in bulk, tape and reel and waffle pack
• Jumpers available (use value code JUMPR in part number)
