Aluminium Housed Power Resistors Type THS Series Type THS Series Characteristics - Electrical THS - 10 Watts to 50 Watts Tyco 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 THS 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 relevant international, MIL or customer specifications.

After moisture test: 1000M 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 Temperature coefficient below 100R, 50ppm/C Temperature coefficient above 100R, 30ppm/C Tolerance, 5% standard Insulation Resistance: Heat Dissipation: Specification: Product Specifications THS10 - THS50 Type L 4.0 Established product with proven reliability * Leading the way with over 50 years of design and manufacturing experience 10 Watts to 50 Watts Versatile product * Bench mark in every industry THS15 15 8 R01 15K 265 1400 1 41500 1 2 hole Characteristics Electrical Key Features THS10 10 5.5 R01 10K 160 1400 1 41500 1 2 hole Dissipation @ 25C with Heatsink (Watts): Without Heatsink: Ohmic Value Min (Ohms): Max: Maximum Working Voltage (DC or ACrms) Volts: Dielectric Strength (AC Peak) Volts: Stability (% resistance change, 1000 hours) (%): Standard Heatsink - Area (mm2): Thickness (mm): Number of Mounting Holes: L THS10, 15 7 THS25, 50 10 5.0 Applications T U L H P M R Dimensions THS10 - THS50 J Braking Resistor Balancing Resistor Capacitor Charging & Discharging Crowbar Filter Electrical Machinery general use Available through Distribution N 2 x Mounting Hole Literature No. 1773277 Issued: 07-06 THS10 - 2.4mm THS25 - 3.3mm THS15 - 2.4mm THS50 - 3.3mm Type H0.3 J0.3 L Max M Max N Max P Max R Min T0.5 U Max THS10 11.3 12.4 17.0 30.0 17.0 9.0 1.9 3.4 2.5 THS15 14.3 15.9 21.0 36.5 21.0 11.0 1.9 5.2 3.2 THS25 18.3 19.8 29.0 51.8 28.0 15.0 2.8 7.2 3.2 THS50 39.7 21.4 51.0 72.5 30.0 17.0 2.8 7.9 3.2 Dimensions are shown for reference purposes only.
