I’m building the * DN05017/D
- power supply from ON Semiconductor. This is the datasheet of the power supply with schematic and BOM So now while searching for the components, I noticed on the schematic and BOM list a resistor without a specific value; all it says is: “TBD”. R11 is the resistor that shows “TBD” Value. And also note under the “Manufacture Part Number”, that capacitors and resistors have “TBD” but under the “Value” they have noted their specific values. Just R11 has noted “TBD”.
I’m integrating this into a AC line monitoring project.
I have googled “TBD” but can’t find my answer.
A definition I found for TBD: “time to breakdown”, but it didn’t make sense in my case, because I need the value.
What does “TBD” mean in this case? Do I have to determine the value by myself?
