Application Notes

Mounting notes:

Since the specified heat sink is required to operate a mounted Video Pack, we recommend the following mounting

technique. (See the thermal design item for details on the required heat sink.) In particular, since the package used for this

product is even more compact than that used in the earlier VPS series, the following points require special care. (These

are recommendations.)

1. A tightening torque of between 0.39 and 0.88 N-m is recommended.

2. The bolt hole spacing in the heat sink should match that of the IC. In particular, the bolt hole spacing should be pulled

in to be as close as possible, within the range that mounting is possible, to the dimensions A and B in the package

dimensions drawing, as shown below.

3. Use either the truss screws (truss bolts) or binding screws stipulated in the JIS standards as the mounting bolts. Also,

use washers to protect the IC case.

4. Foreign matter, such as machining chips, must not be left trapped between the IC case and the heat sink. If grease is

applied to the junction surface, be sure to apply the grease evenly.

5. Solder the IC leads to the printed circuit board after mounting the heat sink to the IC.

Note: The heat sink is absolutely required to operate this Video Pack. Never, in any situation, apply power to a Video

Pack as an independent device. The Video Pack may be destroyed.
