Aluminium Housed Power Resistors
Type HS Series
Characteristics - Electrical
Long Term Stability:
Insulation Resistance:
Heat Dissipation:
Specification:
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 but essential for HSC200, HSC250 & HSC300
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
