THS503K3J

Aluminium Housed Power Resistors Type THS Series Type THS Series Characteristics - Electrical THS - 10 Watts to 75 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: 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 Temperature coefficient below 100R, 50ppm/°C Temperature coefficient above 100R, 30ppm/°C Tolerance, 5% standard Insulation Resistance: Heat Dissipation: Specification: Key Features ■ ■ ■ ■ ■ Braking Resistor Balancing Resistor Capacitor Charging & Discharging Crowbar Filter Electrical Machinery general use Available through Distribution Literature No. 1773277 Issued: 03-08 THS75 8 4.0 10 5.0 Dimensions THS10 - THS50 M L H T ■ 7 THS25, 50 U ■ L THS10, 15 P Applications Type L R ■ Product Specifications THS10 - THS75 J ■ Established product with proven reliability • Leading the way with over 50 years of design and manufacturing experience 10 Watts to 75 Watts Versatile product • Bench mark in every industry N ■ 2 x Mounting Hole THS10 - 2.4mm THS25 - 3.3mm THS15 - 2.4mm THS50 - 3.3mm Type H±0.3 J±0.3 L Max M Max N Max P Max R Min T±0.5 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.
