(.9 to .13 n*m). do not over torque. 5. install leads of the dut into the ms06 on the evaluation board. use #6 self-tapping screws to secure the evaluation board to the hs20 heat sink as shown in the assembly diagram (figure 1). parts list part # description quantity hs20 heatsink 1 eval11 pc board 1 ms06 mating socket 1 ox7r105kwn 1f ceramic capacitor 2 csr07 .1 1% resistor 2 two7 thermal washer 1 package hs22 heatsink 2 before you get started ? all apex ampli?ers should be handled using proper esd precautions. ? always use the heat sink and thermal washers included in this kit. ? always use adequate power supply bypassing. ? do not change connections while the circuit is powered. ? initially set all power supplies to the minimum operating levels allowed in the device data sheet. ? check for oscillations. ? power ground and signal ground must be separated to avoid switching noise in the dut. figure 1.
