WebCTR is defined as the ratio IC/IF (expressed as a percentage) of the output-side transistor collector current IC to the current IF flowing in the input-side LED. Figure 1.2 shows the … WebThe current transfer ratio (CTR) is also a function of temperature. For example, the current transfer ratio (CTR) can vary or change as the temperature (e.g., the operating temperature of the optocoupler system 100) changes. This variation in CTR due to temperature variations is referred to as a temperature coefficient or “tempco” of the CTR.
