SMC SERIES
METAL GLAZETM GENERAL PURPOSE
SURFACE MOUNT, COMPLIANT TERMINAL
·
Capped terminals provide mechanical compliance – relief from
·
board vs component TCE mismatch
Applications – Ideal for automotive and other
harsh thermal applications
Uncompromising MetalGlazeTM performance gives
excellent surge performance
Lead-free, RoHS compliant
Use standard IRC 2512, 3610 solder pads
