ORDERING INFORMATION
TAP600 Series
600 Watt Heat Sinkable Planar
Ohmite’s TAP600 delivers 600
watts of reliable power to a
variety of power conditioning,
power transmission, and power
resistors can be designed for
liquid or air cooled heat sink
systems. Applications include
variable speed drives, power
supplies, robotics, motor con
-
trol, and other control devices.
FEATURES
• Dielectric Strength up to 12KV
• Special Design for Low
Inductance and Capacitance
Values
• Contacts allow for easy load
connection with M5 screws (not
included) available with M4 as
special request.
• Encapsulated with a special resin
filled epoxy casing with a large
creepage distance to mass, large
air distance between terminals,
and a high insulation resistance
(CTI 600).
• Materials meet the requirements
of UL94-V0
• High current version available:
0.1 to 0.2 ohms; 10% tol.

Power Rating:
600W at 70°C heat
sink temperature or 85°C bottom
case temperature. This value
is only valid by using a thermal
conduction to the heat sink R
th
-cs<0.025°C/W.
The value can be reached by
using thermal transfer com
-
pound with a heat conductivity
of 1w/mk. The flatness of the
cooling plate must be better than
0.05mm overall. The roughness
of the surface should not exceed
6.4µm.
