unlimitedfloorlifetimeat≤30°C/85%RH.TheT491standard

terminations are available in 100% matte tin and provide excellent

wetting characteristics and compatibility with today's surface

mount solder systems. Tin/lead (Sn/Pb) terminations are available

upon request for any part number. Gold-plated terminations

are also available for use with conductive epoxy attachment

processes. Standard packaging of these devices is tape and

reel in accordance with EIA 481. This system provides perfect

compatibility with all tape-fed placement units.
