Electrical Isolation - Power Applications
Dielectrics are available in thicknesses from 0.003" (76µm) to 0.009"
(229µm), depending on your isolation needs. See “Electrical Design
Considerations” on pages 16-17 to help determine which thickness is
appropriate for your application.
Thermal Impedance Determines Watt Density
Thermal impedance is the only measurement that matters in
determining the watt density capability of your application because
it measures the temperature drop across the stack-up for each watt
of heat flow. Lower thermal impedance results in lower junction tem-
peratures.The lower the thermal impedance, the more efficiently heat
travels out of the components.

High Power Lighting Applications
HPL is a dielectric specifically formulated for high power lighting LED
applications with demanding thermal performance requirements. This
thin dielectric at 0.0015" (38µm) has an ability to withstand high tem-
peratures with a glass transition of 185°C and phenomenal thermal
performance of 0.30°C/W. For detailed information, call Bergquist
