EYG-IGBT Graphite Sheets Panasonic EYG-IGBT Graphite Sheets are a thermal interface material (TIM) solution designed for use with IGBT modules. The EYG-IGBT series contributes to a long life and increased performance of power modules by providing high thermostability and reliability in thermally sensitive areas. These sheets are easy to install and offer high compressibility (40%, 600kPa) compared to standard PGS. This high compressibility reduces thermal resistance by following gap, warpage, and distortion of targets and substrates. Panasonic EYG-IGBT Graphite Sheets are ideal for the cooling / heat transfer of power modules and other electronic devices that generate heat.
