T428 Series High Volumetric Efficiency Facedown MnO2
Overview
The KEMET T428 Series was developed to provide the volumetric efficiency of a conformally coated capacitor in a pickand-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.
Benefits
• High CV/cc • Taped and reeled per EIA 481-1 • SnPb termination finish • Laser-marked case • 100% surge current test available • Halogen-free epoxy • Capacitance values of 15 to 470 μF • Tolerances of ±5%, ±10% and ±20% • Voltage rating of 4 to 50 VDC • Extended range values • Pick-and-place friendly • RoHS Compliant and lead-free terminations available • Operating temperature range of -55˚C to +125˚C
Applications
Typical applications include decoupling and filtering in telecommunications, computer, industrial, defense and aerospace applications.
