TP400 Series Thermal Pad

TP400 elevates the thermal performance bar, achieving 4.0W/m.K while maintaining a hardness of 55 (shore 00). The low hardness in comparison to thermal conductivity proves that TP400 will meet the demands of your challenging design requirements.
Features: thermal conductivity: 4.0W/m.K, low silicone oil extraction.
Applications: LED lighting systems, power supplies and conversion, semiconductor packaging, IGBTs, automotive, wireless charging, advanced driver assistance systems (ADAS).
