High Heat Conduction Graphite Films

Small heat input areas or transient heat inputs require an especially well-conceived cooling concept with free convection. For efficient cooling of the electronic components, the existing heat must be absorbed quickly, e.g. through a heat sink and dissipated into the environment Here the heat contact of the components on the heat sink plays a crucial role. Fischer Elektronik expands its product portfolio with high heat conduction graphite films of the WLFG series, which also provide excellent solutions for this purpose and also heat spreading. These innovative heat conduction films consist of a highly compressed natural graphite with an application temperature range from -40°C +500°C. The anistrophy of the basic material allows very good heat conductivity in the x, y and z direction. Different models are available in the material strengths of 0.15 to 0.25mm, with an adhesive coating applied on one side for better attachment.
