FEATURES
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.
Applications:
• Input side filtering (power plane/bus)
• High current applications (battery line)
• Circuits that cannot be fused to open when
short circuits occur due to flex cracks
Markets:
• Automotive
- All applications connected directly to the battery
- Conversion to 42V power system
• Power Conversion
- Raw power input side filtering
