The RK73H1ETTP11R3F is a surface-mount thick film resistor manufactured by KOA Speer. It has a resistance of 11.3ohms, a power rating of 0.1 watt, and a tolerance of 1%. The resistor is constructed using thick film technology which consists of a ceramic substrate coated with a thick film of resistive paste. This technology provides improved performance characteristics, such as greater temperature stability, greater accuracy, and superior power handling capabilities over carbon film resistors or other resistor types. It is an ideal choice for applications where a high degree of accuracy is desired, such as power supplies, electronic circuits, or other precision resistive applications.
