Also, all are in the DIP-8 package so they may be easily plugged into a protoboard. All have CTR (current transfer ratio) ranging from 50% to about 500% –quite sloppy. 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. customer home page govqa.us
