High Reliability Commercial Off-the-Shelf (COTS)
T428 Series High Volumetric Efficiency Facedown MnO
2
Overview
The KEMET T428 Series was developed to provide the
volumetric efficiency of a conformally coated capacitor in a pick-
and-place friendly molded package. The planerity of the molded
package eliminates the “drops” associated with the conformally
coated tantalum surface mount devices. This new package
design offers the highest CV/cc of any molded leadframe product.
In addition, the facedown construction offers higher power ratings
per cc. The robust design features and testing protocol make this
part suitable for application in the telecommunications, industrial,
military and aerospace markets.
