Aluminium Housed Power Resistors
Type THS Series

Characteristics - Electrical
THS - 10 Watts to 75 Watts
Tyco are the leading European
supplier of standard and custom
designed
aluminium
housed
resistors for general-purpose use,
power supplies, power generation
and the traction industry.
The THS 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 heatsink.
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.

Characteristics Electrical
Long Term Stability:
For improvements in long-term stability, resistors must be derated as
follows; for 50% of stated ΔR maximum dissipation must not exceed
70% of rating; for 25% of stated ΔR maximum, dissipation must not
exceed 50% of rating
Dry: 10,000MΩ minimum. After moisture test: 1000MΩ 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 of all sizes
