TG500 / T-gard 500 material supercedes Warth K177

For its transistor insulators, MECI now offers the TG500, or Tgard500, from Laird Tech, which is a medium thermal performance transistor insulator pad consisting of a ceramic - filled high temperature silicone rubber coated on an electrical grade fibreglass. The TG500 / T-gard 500 is seen as the natural successor to the now discontinued K177 material from Warth. TG500 / Tgard500 is designed for applications that require additional thickness to prevent electrical shorts from stamped aluminum heatsinks used in switching mode power supplies and debris from aluminum castings used in automotive motor controls. Laird's TG500 / Tgard500 is used in applications that require an interface of 2.5ºC/watt or higher on a TO-220 mounted at 50 psi pressure. Profiles are available for all the popular transistor packages, TO220, TO3 and TO3P, as well as the smaller TO126 size. The standard TG500 / T-gard 500 parts are non-adhesive, but adhesive backed versions are available to special order. Call on 01732 361335 or email info@mecint.co.uk
