DESCRIPTION

Our accessory Thermal Mounting Pads (TMP) provide a simple and effective method of ensuring a low thermal resistance path between a DC/DC converter and its mounting plane. When placed between the converter and circuit board or heat sink, it will provide electrical isolation, fill small surface irregularities, and produce a 0.20°C in2/W (129°C mm2/W) thermal resistance path.

M ATERIAL

The Thermal Mounting Pads, made of silicon rubber and fiber-glass, are thermally stable and non-flammable. They are non-toxic, do not require grease and do not exhibit the cracking problems of ceramic materials. The pads may temporarily react to some cleaning agents (notably chlorinated hydrocarbons) by swelling, but are not damaged after the solvent is removed. They will tolerate soldering process temperatures.M OUNTING

For maximum thermal conduction from the converter through the thermal pad to the thermal plane, a mounting pressure of 300-600 lbs/in2is recommended. To achieve this level of mounting pres-sure, we recommend using our flanged models. The formula to calculate the recommended pressure is P=(T*N)/(0.2*D*A); where P=pressure in PSI, T=torque, N=number of fasteners, D=fastener diameter (in inches), A=contact surface area (in square inches).
