CAPACITOR ORDERING INFORMATION
OPEN-MODE INTERNAL DESIGN
KEMET’s Open Mode Ceramic Surface Mount Capacitor is designed to significantly minimize the probability
of a low IR or Short Circuit Condition when forced to failure in a board flex situation. This reduces the poten-
tial for causing catastrophic failures. This product is RoHS Compliant.
