Tgard 300 Series Thermally Conductive Insulators HIGH PERFORMANCE THERMAL INTERFACE PRODUCTS Tgard 300 is a medium thermal performance insulator pad consisting of a ceramic high temperature silcone rubber coated on electrical fiberglass. Tgard 300 is specifically designed for applications that require low component mounting forces. The unique formulation will enhance thermal performance which minimizes thermal resistance at low mounting forces. The uniqe coating formulation offers an excellent mating surface for low pressure clip mounting applications. FEATURES AND BENEFITS APPLICATIONS High breakdown voltage of 6,000 volts AC Switching mode power supplies Thermal resistance of 0.50 C-in2/watt at 50 psi Industrial equipment Unique coating formulation offers low mounting forces Motor controls Unifying benefits of thermal & electrical performance for general-purpose applications Americas: +1.847 839.6907 IAS-AmericasEastSales lairdtech.com Europe: +44.1628.858941 IAS-EUSales lairdtech.com Asia: ++86.21.5855.0827.127 IAS-AsiaSales lairdtech.com CLV-customerservice lairdtech.com www.lairdtech.com/thermalTgard 300 Series Thermally Conductive Insulators PROPERTIES TEST METHOD METRIC VALUES IMPERIAL VALUES ELECTRICAL PROPERTIES Dielectric withstand voltage ASTM D149 4,500 volts DC 4,500 volts DC 50mm probe for 30 sec Dielectric breakdown voltage Avg >6,000 Avg >6,000 ASTM D149 50mm probe volts AC volts AC 12 12 Volume resistivity ASTN D257 10 ohm-cm 10 ohm-in Dielectric constant 1Mhz ASTN D257 3.3 3.3 Electrical RTI temperature rating UL746D 150C 302F MECHANICAL PROPERTIES Thickness 0.23 mm 0.009 in Hardness ASTM D2240 75 Shore A 75 Shore A Tensile strength ASTM D412 10 Mpa 1.5 Kpsi Elongation 45 to warp/fill ASTM D412 20% 20% Elongation along width or length ASTM D412 5% 5% Operating temperature range -60 to 180C -76 to 356F Color Yellow Yellow UL flammability rating UL 94 V-0 V-0 PRESSURE UNITS 10 25 50 100 200 400 (69) (172) (345) (689) (1379) (2758) TOTAL THERMAL RESISTANCE 2 Modified ASTM D5470 C-in /watt 0.62 0.57 0.50 0.41 0.34 0.30 2 Modified ASTM D5470 C-cm /watt 4.00 3.68 3.09 2.65 2.19 1.94 T0-220 C/watt 1.17 0.92 0.83 0.81 0.80 0.76 Standard thickness: 9 mils (0.229 mm) Configurations available: Sheet form, roll form and die-cut parts Single-side, pressure-sensitive adhesive on request Standard options: Without adhesive (A0): 12 x 18 sheets, 12 x 65M, 12 x 30M roll or custom configuration With adhesive (A1): 11.75 x 18 sheets, 11.75 x 30M roll or custom configuration THR-DS-Tgard-300 032515 Any information furnished by Laird and its agents is believed to be accurate and reliable.
