HEAT SINKING
When to Use a Heat Sink
The Palladium 100 does not require heat sinking in normal service. The
Palladium 250 should be attached to a heat sink or heat sinking surface if
the unit is to be installed in an enclosure, or in deployments where the
ambient temperature could exceed 50
o
C.
Typical Palladium Operating Temperatures
A wide range of variables can affect the temperature of electronic devices
including ambient temperature, air flow, heat sink and mounting consider-
ations.  In a typical test performed at room temperature, the Palladium
250 without a heatsink has been observed to have a baseplate operating
temperature of  40
o
C (104
o
F). The Palladium 100 has been observed to
have a baseplate operating temperature of 37
o
C (99
o
F) in a similar test.
Heat Sink Installation
To install the heat sink, complete the following steps:
1. Align the transmitter and heatsink, with the back of the transmitter
mating with the front, flat surface of the heatsink.
2. Secure the heatsink with four (4) 6-32 x 1” screws. Install the screws
from the transmitter side.
3. Make sure there is good contact between the transmitter and the
heatsink. They should be mounted flush to one another.
