T Metal Baseplate
T Low Thermal Impedance
for Improved Current Capability
Benefits:
T No Additional Insulation
Components Required
T Easy Installation
T No Clamping Components
Required
T Reduce Engineering Time
Applications:
T Bridge Circuits
T AC & DC Motor Drives
T Battery Supplies
T Power Supplies
T Large IGBT Circuit Front Ends
