600 Watt Heat Sinkable Planar
F e at u r e s
Ohmite’s TAP600 delivers 600
watts of reliable power to a
variety of power conditioning,
power transmission, and power
control applications. These resis-
tors can be designed for liquid
or air cooled heat sink systems.
Applications include variable
speed drives, power supplies,
robotics, motor control, and other
control devices.
• Dielectric Strength up to 12KV
• Special Design for Low Inductance and
Capacitance Values
• Contacts allow for easy load connec-
tion with M5 screws (not included)
available with M4 as special request.
Thread depth 7mm
• Encapsulated with a special resin filled
epoxy casing with a large creepage
distance to mass, large air distance
between terminals, and a high insula-
tion resistance (CTI 600).
• Materials meet the requirements of

State
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 Rth -cs<0.025°C/W.
The value can be reached by using thermal
transfer compound 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.
