DT-470-ET / DT-470-MT
DT-470-ET DT-470-MT
Both adapters are gold-plated copper hex head bolts with the SD package mounted in a slot on the adapter head. The
ET adapter screws into a ¼ inch deep, 6-32 threaded hole while the MT adapter screws into a 6 mm deep, 3x0.5 mm
threaded hole. Before assembly the threads should be lightly greased with Apiezon N Grease Do not over-tighten since
the threads are copper and can be easily sheared. Finger tight should be sufficient.
DT-470-BO
The BO adapter should be mounted in the same manner as the CU. The BO adapter
contains its own thermal anchor and is an epoxy free assembly.
DT-470-CO
The CO adapter is a spring-loaded clamp to attach the DT-470-SD package to a flat
surface. It maintains pressure on the SD package as the temperature varies. First,
remove the hold down cap which holds the three piece CO assembly together. The CO
assembly should appear as shown in the accompanying drawings. Bolt the assembly
into a 4-40 threaded hole. The stop on the brass screw should rest against the
mounting surface and it also prevents over-compressing the spring. Lift the edge of the
clip using a small pliers or screw driver. Slide the SD package into place underneath
the clip and gently lower the clip onto the lid of the SD package. Note that a slot is cut
underneath the clip to accept the SD package. Refer to the drawing for details. If the
device is to be used only below 325 K, apply a layer of Apiezon N Grease between the
SD package and mounting surface to enhance thermal contact.
