TAP2000 Series
Ultra High Power Planar Resistor
CHARACTERISTICS
The Ohmite TAP2000 series offers
2000 watts of power dissipation when
properly heatsinked. The design of
the TAP series creates a constant
pressure to the cooling plate of
approximately 300 N for proper ther-
mal flow. The TAP2000 is ideal for
variable speed drives, power supplies,
control devices, robotics, motor con-
trol and other power designs.

Best results can be reached by using a thermal transfer compound
with a heat conductivity of at least 2.9 W/mK. The flatness of the cool-
ing plate must be better than 0.05 mm overall. Surface roughness
should not exceed 6.4 μm.

THIS PRODUCT IS DESIGNED FOR
USE WITH PROPER HEATSINKING.
Maximumbaseplatetemperatureoftheresistormust
be monitored and kept within specified limits to es-
tablish the power rating. Best technique is to attach a
thermocouple to the side of the base plate of the resis-
tor. Temperature of plastic housing or heat sink cannot
be used to establish rating of the resistor.
