TE Connectivity 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 HS 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. TE can
test resistors to conform to relevant international, MIL or customer specifications.
TE are 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.

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
Insulation Resistance: Dry: 10,000MΩ minimum. After moisture test: 1000MΩ minimum.
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 of all
sizes but essential for HSC200, HSC250 & HSC300
Specification: Temperature coefficient below 100R, 50ppm/°C
Temperature coefficient above 100R, 30ppm/°C
Tolerance, 5% standard: 10%, 3%, 2%, 0.5% & 0.25% available
Tolerance for values below R10, 10% standard
