This is a type of power resistor manufactured by Ohmite. It is a two-watt precision resistor with a thermally-sensitive, metal-glass composition housed in a × 0.15" package. It has resistance values from 20 to 10K ohms. It is designed for quick response and stability over long periods of time. It is used for accurate current and voltage monitoring, surge protection, load balancing, switching, linearizing and more.
