Type KHSA Series
Tyco are the leading European
supplier of standard and custom
designed
resistors for general-purpose use,
power supplies, power generation
and the traction industry.
The KHSA is a range of extremely
stable, high quality wire wound
resistors capable of dissipating high
power in a limited space with
relatively low surface temperature.
The power is rapidly dissipated as
heat through the aluminium housing
to a specified heat sink. The KHSA
offers increased dielectric strength
over the standard range of HS
resistors.
The resistors are made from quality
materials for optimum reliability and
stability. Tyco can test resistors to
conform to relevant international,
MIL or customer specifications.
Tyco are happy to advise on the use
of resistors for pulse applications
and to supply information for high
voltage
value, alternative mountings and
termination type.

For improvements in long-term stability, resistors must be derated as follows;
for 50% of stated ∆R maximum dissipation must not exceed 70% of rating;
for 25% of stated ∆R maximum, dissipation must not exceed 50% of rating
Dry: 10GΩ minimum. After moisture test: 1GΩ minimum.
Although the use of proprietary heat sinks with lower thermal resistance is
acceptable, up rating is not recommended.
The use of proprietary heat sink compound to improve thermal conductivity is
recommended for optimum performance
