1 Aluminium oused Power esistors Type S Series Key Features Established product with proven reliability eading the way with over 5 years of design and manufacturing experience 5 Watts to 3 Watts (5 Watt and 1 Watt versions available) argest range on the market Versatile product Bench mark in every industry Custom designs Windings, terminations, mountings - We have a solution for your application ow resistance, low inductance and higher voltage versions available Specialising the standard Applications Braking esistor Balancing esistor Capacitor Charging & Discharging Crowbar Filter Electrical achinery general use Available through Distribution 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 S 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, I 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.

2 Aluminium oused Power esistors Type S Series ong Term Stability: Insulation esistance: eat Dissipation: Specification: For improvements in long-term stability, resistors must be derated as follows; for 5% of stated Δ maximum dissipation must not exceed 7% of rating; for 25% of stated Δ maximum, dissipation must not exceed 5% of rating Dry: 1,Ω minimum. After moisture test: 1Ω 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 SC2, SC25 & SC3 Temperature coefficient below 1, 5ppm/ C Temperature coefficient above 1, 3ppm/ C Tolerance, 5% standard: 1%, 3%, 2%,.5% &.25% available Tolerance for values below 1, 1% standard Derating Curve SA5 to SA5 6 5 SA5 Power (W) SA25 SA1 SA eatsink Temp.
