Open Mode capacitors
X7R
Open Mode capacitors have been designed
specifically for use in applications where
mechanical cracking is a severe problem and
short circuits due to cracking are unacceptable.
Open mode capacitors use inset electrode
margins, which prevent any mechanical cracks
which may form during board assembly from
connecting to the internal electrodes.
When combined with Syfer’s FlexiCap™
termination, Syfer Open Mode capacitors
provide a robust component with the assurance
that if a part becomes cracked, the crack will be
unlikely to result in short circuit failure.
Open Mode capacitor - Untested
Open Mode capacitor - Qualification included cracking the
components by severe bend tests. Following the bend tests
cracked components were subjected to endurance / humidity
tests, with no failures evident due to short circuits.
Note: Depending on the severity of the crack, capacitance loss
was between 0% and 70%.
