The OHMITE MANUFACTURING TFH85M51R0JE is a high-performance thick film resistor designed for demanding electronic applications. This through-hole resistor offers a robust 85-watt power rating at 25°C case temperature, making it suitable for power-intensive circuits requiring reliable thermal management.
Key Features
85 Watt power rating at 25°C case temperature
Non-inductive performance for precise applications
This product is designed for use with proper heatsinking. The maximum base plate temperature must be monitored and kept within specified limits to ensure reliable operation. The best technique is to attach a thermocouple to the side of the base plate of the resistor. The temperature of the plastic housing or heat sink cannot be used to establish the resistor’s rating.
For detailed specifications, please refer to the datasheet.
