Aluminium-housed power resistors

1 June 2005 Passive Components

Tyco Electronics is a leading European supplier of standard- and custom-designed aluminium housed resistors for general-purpose use, power supplies, power generation and the traction industry.

The company's HS type 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 No. 1773035 relevant international, MIL or customer specifications.

Tyco can also 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 types.

The type HS can handle up to 300 W with heatsink and up to 2,5 kV d.c. operating voltage. Temperature coefficient below 100 Ω is 50 ppm/°C while above 100 Ω, is 30 ppm/°C. Tolerance is 5% standard, and 10%, 3%, 2%, 0,5% and 0,25% is available. 10% tolerance is standard for values below 10 Ω.
