UL94-V0
characteristics
Resistance Values
0.25Ω to 100KΩ
Resistance Tolerance
±10% Std., 5% available on request.
Temperature Coefficient
±150ppm/°C (others upon request)
Maximum Working Voltage
5,000V DC, higher voltage on request, not
exceeding max. power
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 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.

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.
The Ohmite CP4 (http://www.ohmite.com/cat/sink_cp4.
pdf) is an example of properly designed heat sink.
