Type HSX Series
Tyco Electronics is 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 HSX range consists of extremely
stable, high quality wire wound
resistors capable of dissipating high
power in a limited space with
relatively low surface temperatures.
The power is rapidly dissipated as
heat through the aluminium housing
to a specified heatsink. The HSX
offers increased creep distance
by virtue of a remodelled
and extended nosecone.
The resistors are made from quality
materials for optimum reliability and
stability. Tyco Electronics can test
resistors to conform to relevant
international, MIL or customer
specifications.
Tyco Electronics is happy to
advise on the use of resistors for
pulse applications and to supply
information for high voltage use and
low-ohmic value, alternative
mountings and termination type.

Environmental Category: -55/200/56 -55/200/56 -55/200/56
Long Term Stability: 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
Insulation Resistance: Dry: 10GΩminimum. After moisture test: 1GΩminimum.
Heat Dissipation: 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.
Specification: Temperature coefficient below 100R, 50ppm/°C
Temperature coefficient above 100R, 30ppm/°C
Tolerance, 5% standard: 10%, 3%, 2%, 0.5% & 0.25% available.
