One world. One KEMET

Overview

KEMET’s Ceramic Open Mode capacitor in X7R dielectric

is designed to significantly minimize the probability of a low

IR or short circuit condition when forced to failure in a board

stress flex situation, thus reducing the potential for catastrophic

failure. The Open Mode capacitor may experience a drop in

capacitance; however, a short is unlikely because a crack

will not typically propagate across counter electrodes within

the device’s “active area.” Since there will not be any current

leakage associated with a typical Open Mode flex crack,

there is no localized heating and therefore little chance for a

catastrophic and potentially costly failure event.

Driven by the demand for a more robust and reliable

component, the Open Mode capacitor was designed for

critical applications where higher operating temperatures and

mechanical stress are a concern. These capacitors are widely

used in automotive circuits as well as power supplies (input and

output filters) and general electronic applications.

Concerned with flex cracks resulting from excessive tensile

and shear stresses produced during board flexure and thermal

cycling? These devices are available with KEMET's Flexible

termination technology which inhibits the transfer of board

stress to the rigid ceramic body, therefore mitigating flex cracks

which can result in low IR or short circuit failures. Although

flexible termination technology does not eliminate the potential

for mechanical damage that may propagate during extreme

environmental and handling conditions, it does provide superior flex

performance over standard termination systems. When combined

with flexible termination technology these devices offer the ultimate

level of protection against a low IR or short circuit condition. Open

Mode devices compliment KEMET's Floating Electrode (FE-CAP)

and Floating Electrode with Flexible Termination (FF-CAP) product

lines by providing a fail-safe design optimized for mid to high range

capacitance values. These devices exhibit a predictable change in

capacitance with respect to time and voltage and boast a minimal

change in capacitance with reference to ambient temperature.

Capacitance change is limited to ±15% from −55°C to +125°C.
