EVALUATION KIT
EK14 is an easy to use engineering platform for prototype
evaluation. Provided items include: PC board, heatsink rated
at 1.3°C/W, mating socket, thermal washers, two ceramic
bypass capacitors and two 0.15 ohm current sense resistors.
The amplifier is sold separately. Common hardware such as
screws, nuts and user’s preference for I/O connectors are
not provided.
HEATSINKS
The following heatsinks are mechanically compatible with
this amplifier. Thermal ratings are for optimum mounting in
free air.
HS20 1.3°C/W
The HS20 is designed to be fastened vertically to a PC
board with screws.
HS27 5.3°C/W
The HS27 is designed to be fastened vertically to a PC
board by soldering.
Many other heatsinks can be used with this amplifier if a
hole is drilled and deburred. Requirements for the potential
heatsink or chassis member are flatness of 2 mils per inch in
an area large enough to fit the package.
SOCKET
MS06
Part number MS06 consists of two strips of 20 connectors on
0.1” centers. The strip can easily be cut to desired length.
THERMAL WASHER
TW07
NOTES:
1. Base material is aluminum, 0.002” thick. Do not allow the
washer to touch pins of the amplifier.
2. For optimum thermal transfer, avoid abrasive handling
of washers which can damage their 0.5mil thick layer of
thermal compound with which each side is coated.
3. The dry thermal compound will flow filling header to heatsink
voids as soon as the material reached 60°C.
4. Do not store unused thermal washers above 40°C.
5. A new washer must be used for each mounting.
6. Part number TW07 consists of a package of 10 washers.
7. Thermal resistance is 0.1°C/W.
This data sheet has been carefully checked and is believed to be reliable, however, no responsibility is assumed for possible inaccuracies or omissions. All specifications are subject to change without notice.
