Insulating Material Guards PC Power Supplies April 2007 Issue Published Date: April 09, 2007
Designed for computer power supply applications, T-gard 20 is described as a high-performance, cost-effective electrically conductive insulating material. It features a 9-kVac dielectric breakdown voltage, said to be the contributing factor to the material's high electrical reliability. Producing the same thermal performance whether the device is screw or clip mounted, thermal impedance is 0.6°C-in.2/W. The phase change coating melts into a grease-like paste at 52°C and completely wets out the interface to accommodate rough and non-flat surfaces. Other features include a tensile strength of 30,000 psi. Price is less than $0.01 per square inch. LAIRD TECHNOLOGIES, St. Louis, MO. (800) 843-4556.
