Tales from 80s Tech: If the opto is connected to some 5 volt logic gate or controller. You will have values well inside the spec of the opto. As regards the resistance of the transistor, which logic do i use? If you feel for it use two resistors in series to get close to the value.

No, create an account now. There is a simple formula to calculate the two resistor for each optocoupler?

Do you already have an account? I guess a 4. And the higher current. You do not need a value that is ohm. It should be easy now to get a picture of the resistor wattage.

May 11, 5, 1, In summary, hereafter you can see the formulas for resistors wattage: This will give you the LED voltage drop for a given current. Jan 16, 7 0. Jan 22, 7.

daatsheet Yes, my password is: Keep your kids engaged and get them excited about electrical engineering with these fantastic sites. You can use figure 2. Posted by rjjenkins in forum: Quote of the day. Jan 22, 8. And that is also important. But use a emitter resistor in the range of 4. Go for a LED current equal to 15mA. Jan 22, 5. The voltage drop in the transistor will be typical. This will show the voltage drop versus current. So the current in a 4. Jan 20, 2. Hello people, i’m new to electronic circuits.


Have you done any calculations on LEDs and transistors before? Jan 22, 3. By using a 4.

The higher Vce voltage drop. Your name or email address: Assume using figure 2 in the datashdet. We see that the Saturation voltage, collector emitter will be at typical. I will use a trimmer instead a resistor.
