Electrical The THS is a range of extremely stable, high quality wire wound Long Term Stability: For improvements in long-term stability, resistors must be derated as resistors capable of dissipating follows for 50% of stated R maximum dissipation must not exceed high power in a limited space with 70% of rating for 25% of stated R maximum, dissipation must not exceed 50% of rating relatively low surface temperature. The power is rapidly dissipated Insulation Resistance: Dry: 10,000M minimum. After moisture test: 1000M minimum. as heat through the aluminium Heat Dissipation: Although the use of proprietary heat sinks with lower thermal housing to a specified heatsink. resistance is acceptable, up rating is not recommended. The use of proprietary heat sink compound to improve thermal The resistors are made from quality conductivity is recommended for optimum performance of all sizes materials for optimum reliability and Specification: Temperature coefficient below 100R, 50ppm/C stability. Tyco can test resistors to conform to relevant international, Temperature coefficient above 100R, 30ppm/C MIL or customer specifications.
