- Thermal impedance: 0.13°C-in[2] /W (@25 psi) 

- Field-proven polyimide film 

- excellent dielectric performance 

- excellent cut-through resistance 

- Outstanding thermal performance in an insulated pad 

Hi-Flow 300P consists of a thermally conductive 55°C phase change compound coated on a thermally conductive polyimide film.The polyimide reinforcement makes the material easy to handle and the 55°C phase change temperature minimizes shipping and handling problems. 

1) This is the measured thermal conductivity of the Hi-Flow coating. It represents one conducting layer in a three-layer laminate.The Hi-Flow coatings are phase change compounds.These layers will respond to heat and pressure induced stresses.The overall conductivity of the material in post-phase change, thin film products is highly dependent upon the heat and pressure applied.This characteristic is not accounted for in ASTM D5470. Please contact Bergquist Product Management if additional specifications are required. 2) The ASTM D5470 test fixture was used and the test sample was conditioned at 70°C prior to test.The recorded value includes interfacial thermal resistance.These values are provided for reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied. 

Hi-Flow 300P achieves superior values in voltage breakdown and thermal performance when compared to its competition. The product is supplied on an easy release liner for exceptional handling in high volume manual assemblies. Hi-Flow 300P is designed for use as a thermal interface material between electronic power devices requiring electrical isolation to the heat sink. 

## **Typical Applications Include:** 

- Spring / clip mounted 

- Discrete power semiconductors and modules 

## **Configurations Available:** 

- Roll form, die-cut parts and sheet form, with or without pressure sensitive adhesive 

Bergquist suggests the use of spring clips to assure constant pressure with the interface and power source. Please refer to thermal performance data to determine nominal spring pressure for your application.
